1,065,296 | Debris Flow | CALIFORNIA | MADERA | 2023-01-10T21:11:00 | 2023-01-10T23:11:00 | A strong low pressure system moved through central California on January 9 and 10. This system picked up a deep moisture fetch of tropical origin while tracking rapidly eastward across the Pacific and produced widespread heavy precipitation across the area between the morning of January 9 and the evening of January 10 while the deep surge of moisture moved inland across central California. This storm produced widespread liquid precipitation totals of 3 to 6 inches in the Sierra Nevada. For much of this event, the snow level was around 7500 feet which resulted in heavy runoff of snow accumulations from recent colder storms. This runoff combined with rainfall of 2 to 4 inches in the Sierra foothills and 1 to 2.5 inches in the San Joaquin Valley to produce widespread flooding across the area with at least 150 separate incidents of flooding being reported to the Hanford NWS office. The flooding resulted in numerous roads being closed and several evacuations took place including the entire town of Planada in Merced County which was inundated with flood waters. In addition, Bear Creek overflowed it's banks and reached a new record peak flood of 26.2 feet at McKee Bridge east of Merced on January 10. Above the snow line, there were several reports of 2 to 4 feet of new snowfall above 7500 feet in the Sierra Nevada. This system also produced strong downslope winds on January 9 with several stations in the Tehachapi Mountains, West Side Hills and Sierra foothills measuring gusts exceeding 60 mph and resulting in several power outages across the area as power lines were blown down by the strong winds. Thunderstorms broke out across the much of the area on January 10 as colder air aloft moved over the area resulting in numerous issuances of Significant Weather Advisories along with a few warnings. The storm moved to the east of the area on January 11 with precipitation ending and winds diminishing. However, flooding continued across much of the area due to residual runoff from the heavy precipitation that fell over the previous two days. Several county Emergency Operations Centers were staffed by NWS personnel during this event do to the unusual severity with this storm as numerous warnings were issued for flooding, strong winds and heavy mountain snowfall. California Highway Patrol reported a mudslide on SR 41 at Road 415 in Coarsegold. | [

988,991 | Debris Flow | CALIFORNIA | TULARE | 2021-12-14T13:14:00 | 2021-12-14T16:14:00 | A strong low pressure system dropped southeast out of the Gulf of Alaska on December 12 and intensified off the Pacific Northwest coast on December 13 pulling up some deep moisture which was pushed into central California during the afternoon. The precipitation intensified during the evening of December 13 through the morning of December 14 as the low carved out a deep upper trough which pushed across California during the afternoon of December 14. This system produced 2 to 4 inches of liquid precipitation over the Sierra Nevada from Sequoia National Park northward and 1 to 3 inches of liquid precipitation south of Sequoia Park. The precipitation fell mainly in the form of snow above 5500 feet and several high elevation SNOTELs estimated 2 to 4 feet of new snowfall. The snow level lowered to as low as 1500 feet during the evening of December 14 as the cooler airmass behind the system pushed into central California. Much of the San Joaquin Valley picked up between 1 to 2 inches of rainfall while the Kern County Mountains picked up between 0.75 and 1.5 inches of liquid precipitation. The Kern County Desert areas only picked up between a quarter and a half inch of rain at most locations due to rain shadowing. The storm produced widespread minor nuisance flooding in the San Joaquin Valley and Sierra foothills with a few rock slides noticed. Several roads were closed as a precaution and chain restrictions were implemented on some roads in the Sierra Nevada. The storm also produced strong winds over the West Side Hills as well as in the Grapevine and Tehachapi areas in Kern County. Several stations in these areas measured wind gusts exceeding 50 mph with a few locations near the Grapevine measuring brief gusts exceeding 70 mph. California Highway Patrol reported mud, rock and dirt covering most of North Plano St. near Lynch Dr. | [

931,869 | Debris Flow | ALASKA | HAINES BOROUGH | 2020-12-01T22:00:00 | 2020-12-03T12:00:00 | A large plume of concentrated moisture or Atmospheric River (AR) with an associated low-pressure system moved across the Pacific Ocean and transported tropical moisture from the southwest which impacted Southeast Alaska (SEAK) from December 1st through December 2nd. This event brought widespread significant, and sometimes historic record setting rainfall to locations across Southeast Alaska. There were multiple waves along the main front to produce a quasi-stationary front and allowed heavy precipitation to persist over the panhandle for a long duration. Rainfall amounts were as high as over 15 at Little Port Walter with most other locations reporting 5 to 12 over the 2 days. Juneau, Skagway and Haines airports broke their all time daily precipitation record on December 1st along with the all time 2 day total when both days are combined. Rainfall intensity recurrence intervals ranged from a 50 to 200 year event when looking at 6,12,24,48 hour time periods. In some locations the precipitation started out as snow, minor accumulations but then changed quickly over to moderate/heavy rain. Significant snowfall did occur mainly at high elevations and along the Haines and Klondike highways before transition to rain as temperatures rose above freezing all the way up to 6000 feet with the impacting warm front. Snow accumulations were very impressive from December 1st into the 2nd with 18 at 800 feet near the Haines US customs border station and a staggering 59 at 2560 feet on Mount Ripinski above Haines. There was persistent precipitation that occured the previous weeks to keep the soils on the wet side. The heavy precipitation and warm temperatures melted snow that had already accumulated on the ground at sea level then as the snow level climbed above the mountain top this increased the amount of runoff significantly from the mountains. All the excess runoff resulted in significant and in places record flooding of roads and homes, erosion that damaged roads and infrastructure, and widespread mass wasting events such as landslides and debris flows. Most of these impacts were reported to have started in the early morning hours of December 2nd and persist into December 3rd or longer. The northern half of Southeast Alaska saw most if not all of these impacts with a few specific rivers, Salmon River in Gustavus and Jordan Creek in Juneau, seeing record river stage values. Widespread damaging debris flows impacted Juneau, Skagway and Haines that took out roads, destroyed homes and caused 2 fatalities in Haines. ��To go along with the heavy precipitation there was also very strong damaging winds as the waves moved along the front over the panhandle. These strong winds damaged power lines from falling trees.��In total there were about 7 communities (Haines, Juneau, Skagway, Gustavus, Hoonah, Tenakee Springs, and Hyder) that declared a disaster from this event. As the atmospheric river moved over the far north central inner channels of Southeast Alaska it produced significant amount of precipitation from December 1st-2nd. Heavy to moderate rainfall persisted over 48 hours with the highest amounts coming during the afternoon hours of December 1 through late morning of December 2nd. By mid morning on December 1st, near 2 of precipitation already fell. The snow levels were low at the start of the event with a few inches at sea level in Haines but as much as 12 was reported at 800 feet by the Haines40NW COOP and 20 at the 2500 foot Flower Mt SNOTEL site by the morning of December 1st. Closer to Haines, the Ripinski ridge weather station at 2560 feet reported an estimated snow accumulation of near 59 from before the warm air moved into the area. The snow level rose rapidly through the evening of December 1st to be above the mountain tops by the early morning hours of December 2nd. This warming at elevation melted the fresh snow that fell with Ripinkis Ridge losing close to 30 and Flower Mt losing near 20 by the afternoon of December 2nd. By the end of December 1st the Haines airport reported a 24 hour precipitation amount of 5.49 which was a 25 to 50 year event and broke the all time daily precipitation record from 1946. The Haines COOP reported at 7am AKST on December 2nd a 24 hour amount of 6.62 which also broke the all time daily precipitation record from 2005. Haines40NW COOP along the Haines Hwy reported at 7am AKST on December 2nd a 24 hour precipitation amount of 5.23 a new all time daily precipitation record beating out 1999 and a 25 year event. From December 1st to the 2nd precipitation amounts from the downtown Haines COOP were 8.54���, Haines Airport 10.26��� a 200-500 year event, and the Haines40NW COOP 8.12��� a 50-100 year event, were all time 48 hours precipitation records. From December 1st to 3rd 10 to 10.50 of precipitation fell from downtown Haines to the Haines border with a 100 to 200 year event. All of this heavy rainfall and snow melt produced significant impacts in the Haines area. In the early hours of December 2 after all-time record rainfall, saturated soils, and a deep snowpack, a second impulse of heavy precipitation moved over the area, and the snow level rose above 2500ft. The rising snow level began to melt the fresh snowfall at high elevation to produce significant amount of runoff that overwhelmed drainage ditches and culverts. The intense runoff began to erode the roads at the base of Ripinski Ridge and by day break there was significant infrastructure damage to all roads near Ripinski ridge which left Piedad Rd, Cathedral View Dr, Allen Rd, Comstock Rd, 4th ave,Young Rd to name a few that were impassable as the roads were washed away from erosion. There was also significant flooding away from the steep terrain from poor drainage not keeping up with the amount of runoff. Up to 4 feet of water flooded the Haines Hitch-Up RV park along with flooding across places at the Haines airport essentially closing it down to flights. To go along with the major road infrastructure damage there were a number significant major debris flows from the intense precipitation, super saturated soils and strong winds to help trigger the slides that blocked roads and damaged homes near steep terrain. Haines was cut off from the Canadian Border and the airport due to debris flows blocking the Haines Hwy. There were also multiple debris flows along Lutak Rd that damaged the Lutak fuel Dock, blocked the road in multiple locations and isolated residence in a subdivision at the end of the road. A few homes at the end of Lutak Rd we significantly damaged from debris flows coming down behind their homes with one getting pushed off its foundation, another with debris in the house and another with minor damage. Mud Bay Rd was blocked by a debris flow which isolated another part of town. A large avalanche came down into Chilkat Lake out the Haines Hwy that damaged a few homes. Residence in the affected areas and other locations near steep terrain were evacuated to emergency shelters throughout the morning of December 2. Heavy rain continued into the afternoon hours and around 130pm AKST a massive landslide occurred along Beach Rd that took out a 200 yard section of the road, destroyed 2 homes while causing major damage to another. One of the destroyed homes was not occupied but the other had to 2 people inside. The 2 people perished from the landslide or what the geologist are calling a geologic mass wasting event. There were about a half dozen homes on the south side of the slide that were evacuated due to the threat of another very large landside. It continued to be very wet with freezing levels going up and down to keep increase runoff not just from the precipitation but also from snow melt for the next week with a 7 day total of 14.85 which is a near 150 year event. The continue precipitation on the super saturated soils kept the threat of more debris flows high through December 7th. There was some minor movements of a home near an old landslide from 2012 called the slump area. This was one of the most impactful flooding and debris flow event since 2005 or ever and the data backups extreme impacts. The city of Haines declared a disaster for this event from the widespread and extensive infrastructure damage, 2 homes destroyed, 7 homes with major damage, 16 homes with minor damage with another 12 home adversely affected from the area damage and the 2 deaths. The governor of Alaska also declared a disaster emergency for Southeast Alaska from the impacts of this event. | [

Numerous trees were uprooted as a result of the strong winds. Temperatures plummeted on February 22 leading to low-elevation snow and cold-core thunderstorms.||The second, and highly impactful, next wave of the storm system enveloped Southern California starting on February 23. This is the period of heaviest snowfall, and a first-ever Blizzard Warning issued by NWS San Diego was in effect for the San Bernardino County Mountains. Heavy snowfall persisted through early morning on February 26, resulting in FEET of snowfall in the mountains, with many locations in the San Bernardino County Mountains seeing over 50 of snowfall. This resulted in hard closures of many highways in the San Bernardino County Mountains and left people trapped in their homes. Snow levels once again fell on February 25, with snow levels as low as 1000-2000 feet in the Inland Empire and inland Orange County. Widespread heavy thunderstorms occurred leading to local flooding, especially across San Diego County, inland Orange County and portions of the Inland Empire, as well as produced pea size hail.||The impacts of this system, especially in San Bernardino County, would be further exacerbated by an additional significant storm system that would hit only days later, leading to additional FEET of snow. The Department of Highways reported a vehicle stuck in mud on Cleghorn Road off of SR-1138. Search and rescue in place at midnight. | [

798,028 | Debris Flow | CALIFORNIA | TULARE | 2019-02-13T09:00:00 | 2019-02-13T12:00:00 | A deep moisture plume moved through central California on February 13 and 14 as a strong low pressure system approached the area. Heavy rainfall and strong southerly winds impacted the area as this moisture moved through the area. Several reports of winds gusts exceeding 60 mph were reported and snow levels rose to near 9000 feet which resulted in widespread flooding in the area and several road closures from flooding and debris flows were reported. A strong cold front pushed through the area during the morning of February 15 which resulted in snow levels plummeting to around 5000 feet. Thunderstorms broke out in the colder and unstable post-frontal airmass and several reports of small hail were observed in the San Joaquin Valley. In addition, a small EF 0 tornado briefly touched down n ear Yosemite Lakes and funnel clouds were observed in the San Joaquin Valley. A colder system moved into the area on February 16 and snow levels lowered further down to 1500 feet. Low elevation snowfall on February 16 and 17 resulted in numerous road closures and travel delays and there were several reports of 10 to 20 inches of new snowfall reported in the Southern Sierra Nevada between the evening of February 15 and the evening of February 17. Rainfall totals between February 13 and February 17 were generally between 3 and 7 inches of liquid precipitation in the higher elevations of the Southern Sierra Nevada with 2 to 5 inches in the adjacent foothills. Much of the San Joaquin Valley picked up between a half inch and an inch and a half of rainfall during this period while the Tehachapi Mountains generally picked up between 1 to 2 inches of liquid precipitation during the 5 day period. The Tulare County Emergency Manager reported a mudslide at the intersection of Bear Creek Road and Balch Park Road. | [

1,005,323 | Debris Flow | KENTUCKY | CLAY | 2022-01-01T11:00:00 | 2022-01-01T11:00:00 | The second warmest December on record for Eastern Kentucky finished with a warm and moist air mass in place on New Year's Eve. A developing warm front slowly lifted northward out of the Tennessee Valley during the early morning hours on New Year's Day 2022 and stalled near the the Hal Rogers/Highway 80 corridor. The combination of strong lifting and near record atmospheric moisture levels for this time of year led to a line of training showers and thunderstorms, some with frequent lightning and intense downpours. The heaviest rainfall occurred from about 4 to 8 AM and led to many instances of flash flooding from Rockcastle County east northeast through Jackson, Owsley, Breathitt, Floyd, and Pike counties. By midday, locations affected by this activity had received 2 to 4 inches of rainfall. ||A temporary lull in the showers followed as the front shifted further to the north during the late morning and early afternoon. This allowed temperatures to surge into the 60s across the northeast Kentucky and into the lower to middle 70s closer the Kentucky/Tennessee border. ||Strong to severe thunderstorms developed in a high shear, low instability environment during the afternoon as a cold front swept from northwest to southeast across the area. While these storms mainly produced damaging wind gusts, one storm produced a brief spin-up tornado in far northwest Estill County. Impacts did not end with the passage of the cold front though; the excessive rainfall from earlier in the day quickly found its way into the mainstem rivers, sending multiple locations along the Kentucky and Red Rivers into flood stage. The most significant river flooding of the event ��� Moderate flood ��� was attained along the Kentucky River at Ravenna, the Red River at Clay City, and the South Fork Kentucky River at Booneville. A few other locations surpassed Minor flood stage. Clay County 911 reported a mudslide along KY-1350 about 5.5 miles up, near the community of Sexton's Creek. | [

801,346 | Debris Flow | CALIFORNIA | KERN | 2019-03-06T03:32:00 | 2019-03-07T12:00:00 | A strong and very moist upper low pressure system approached the central California coast on March 5. This system pulled up a deep fetch of moisture of sub-tropical origin which pushed into the area during the evening of March 5 then stalled over the southern portion of central California during the morning of March 6 as a strong southwest upper jet was overhead. This resulted in widespread heavy precipitation over Kern County with moderate to locally heavy precipitation further north over an already saturated ground producing widespread flooding, debris flows, rock slides and mud slides across the area. Several roads were closed as a result of the flooding. Thunderstorms broke out during the afternoon producing additional moderate to locally heavy rainfall. Much of the Southern Sierra Nevada picked up between 2 and 4 inches of liquid precipitation with the snow level running between 8000 and 8500 feet for much of the event. Between 1 to 3 inches of rain fell in the adjacent foothills and across the Kern County Mountains. Kelso Creek to the southeast of Lake Isabella filled up that a potential levee breach led to an evacuation of the communities of Weldon Valley Ranchos, Valley Estates and Power Tracts within the town of Kelso Creek. State Route 178 was closed in Kern Canyon for two days due to a rock slide. Much of the San Joaquin Valley and Kern County Deserts picked up between a half inch and an inch of rain while locally heavier amounts fell in the south end of the San Joaquin Valley and across the Indian Wells Valley, and as a result road flooding was widespread in Kern County. California Highway Patrol reported a rock slide in the area of Burlando Rd. and Kernville Rd. in Kernville. | [

Between 1 to 3 inches of rain fell in the adjacent foothills and across the Kern County Mountains. Kelso Creek to the southeast of Lake Isabella filled up that a potential levee breach led to an evacuation of the communities of Weldon Valley Ranchos, Valley Estates and Power Tracts within the town of Kelso Creek. State Route 178 was closed in Kern Canyon for two days due to a rock slide. Much of the San Joaquin Valley and Kern County Deserts picked up between a half inch and an inch of rain while locally heavier amounts fell in the south end of the San Joaquin Valley and across the Indian Wells Valley, and as a result road flooding was widespread in Kern County. California Highway Patrol reported rocks in the traffic lanes if Interstate 5 at the intersection of Fort Tejon Rd. near Lebec. | [

The combination of all the heavy rainfall led to significant flooding across a good portion of central and east Kentucky. For some areas, this was the most significant flooding in the last 50 to 60 years, or more. FEMA estimates that this event cost $350-400 million dollars in damages, including both individual and public infrastructure. This is now the costliest event in Kentucky to date.||The first round of heavy rain came through on the morning of Saturday, February 27th. This early rainfall targeted areas along the Hal Rogers Parkway, including Laurel, Clay, Perry, and Knott counties. Flash flooding let to some closed roads for a short time in these areas. ||The second round of rainfall occurred late Saturday night as a warm front lifted northward across east Kentucky. The heavy rain stalled out over portions of Powell and Menifee Counties, leading to flash flooding into the early morning hours of Sunday.||Finally, the third round of heavy rain started late Sunday afternoon and continued through Sunday night. Given that much of the area had already received significant amounts of rain from the past two events, the ground was very saturated, and this last round caused widespread flash flooding across much of east Kentucky. As water made it's way to the larger creeks and rivers, these began to flood as well. River levels on the Kentucky river were some of the highest readings ever recorded, namely at Booneville and Ravenna. Clay City, Heidelberg, Jackson, Paintsville, and Salyersville also saw significant river flooding of which hadn't been seen in 40 to 50 years. ||The periods of heavy rain and flooding led to numerous water rescues and mud/rock slides. Many areas were cut off or blocked due to the flooding. Power outages were also noted and reached as high as 12,000 during the peak of the flash flooding Sunday night. A mudslide is blocking one lane on KY-1499 at mile marker 3. | [

The system then turned inland and moved through southern California during the evening of December 25 through the morning of December 26 bringing moderate to heavy precipitation to much of Kern County with lighter amounts further north. Between 1 and 2 inches of liquid precipitation fell across much of Kern County with the snow level between 2500 and 3000 feet. Above the snow line, 1 to 2 feet of new snowfall was reported at several stations and the heavy snowfall resulted in the closure of several highways (including Interstate 5 south of Grapevine) for an extended period of time during a period of normally heavy holiday traffic after several vehicle either slid off of the highway or spun out. One truck driver was killed after being stranded along Interstate 5 for several hours. Across the Kern County Deserts and in the San Joaquin Valley from Bakersfield southward, heavy rainfall resulted in several roads being closed for a few hours with several reports of nuisance flooding reported by the Emergency Managers office or by law enforcement. There were also several reports of strong wind gusts and some reports of minor wind damage in the Fort Tejon and Tehachapi areas. Further north precipitation amounts were significantly lower although parts of Kings County picked up between a quarter and three quarters of an inch of rainfall. The remainder of the area generally picked up a quarter of an inch or less of liquid precipitation before the system moved to the east of the area during the evening of December 26.

A developing warm front slowly lifted northward out of the Tennessee Valley during the early morning hours on New Year's Day 2022 and stalled near the the Hal Rogers/Highway 80 corridor. The combination of strong lifting and near record atmospheric moisture levels for this time of year led to a line of training showers and thunderstorms, some with frequent lightning and intense downpours. The heaviest rainfall occurred from about 4 to 8 AM and led to many instances of flash flooding from Rockcastle County east northeast through Jackson, Owsley, Breathitt, Floyd, and Pike counties. By midday, locations affected by this activity had received 2 to 4 inches of rainfall. ||A temporary lull in the showers followed as the front shifted further to the north during the late morning and early afternoon. This allowed temperatures to surge into the 60s across the northeast Kentucky and into the lower to middle 70s closer the Kentucky/Tennessee border. ||Strong to severe thunderstorms developed in a high shear, low instability environment during the afternoon as a cold front swept from northwest to southeast across the area. While these storms mainly produced damaging wind gusts, one storm produced a brief spin-up tornado in far northwest Estill County. Impacts did not end with the passage of the cold front though; the excessive rainfall from earlier in the day quickly found its way into the mainstem rivers, sending multiple locations along the Kentucky and Red Rivers into flood stage. The most significant river flooding of the event ��� Moderate flood ��� was attained along the Kentucky River at Ravenna, the Red River at Clay City, and the South Fork Kentucky River at Booneville. A few other locations surpassed Minor flood stage. Clay County 911 reported a mudslide onto the Hal Rogers Parkway around mile marker 11 in western Clay County. | [

This system had an atmospheric river associated with it which contained a deep fetch of moisture of tropical origin resulting in widespread moderate to heavy precipitation across the area with the snow level ranging between 7000 and 8000 feet for much of the event. Several stations above 8000 feet picked up 18 to 30 inches of new snowfall from this storm. Many stations in the Sierra Nevada picked up an inch and a half to three inches of liquid precipitation while the adjacent foothills picked up 1 to 2 inches of rain and the San Joaquin Valley received around a half inch to an inch from Fresno County northward and a quarter to a half inch further southward. This rainfall came on top of already saturated soils from the late December storms resulting in widespread nuisance flooding across the area. The Tehachapi Mountains generally picked up between a quarter to a half inch of rainfall while rain shadowing effect limited rainfall in the Kern County Deserts to a tenth of an inch or less at most stations. This system also produced very strong winds across much of the area with several stations in the Kern County Mountains and West Side hills measuring gusts in excess of 60 mph with several ridge top stations in Kern County reporting peak gusts in excess of 75 mph. Several reports of wind damage were received by WFO Hanford during this event. Tulare County Sheriffs reported a small rock slide on Pleasant Oak Dr. near the intersection with SR 190. | [

This system had abundant moisture associated with it as it pulled up a deep fetch of moisture of tropical origin. This system brought widespread moderate to heavy precipitation to the area between the early morning until the early evening of December 27. The heavy rainfall produced a rockslide in Yosemite National Park which resulted in two fatalities. The precipitation tapered off by the early morning of December 28. Much of the higher Sierra Nevada picked up between an inch and a half and three inches of liquid precipitation with the precipitation mainly falling as snow above 7500 feet where many stations picked up between 18 and 30 inches of new snowfall. The snow level briefly lowered to around 6000 feet during the evening of December 27 and some light snowfall was observed between 6000 and 7500 feet. The Sierra foothills generally received between 1 to 2 inches of rain while 0.75 to 1.5 inches of rain fell in the San Joaquin Valley and the Tehachapi Mountains. Several reports of nuisance flooding were reported by law enforcement and on social media. Rain shadowing effects limited precipitation in the Kern County Deserts to a quarter inch or less. This system also brought some strong wind gusts to the mountains as several stations measured gusts exceeding 40 mph and a few low impact stations had brief gusts above 60 mph. Yosemite National Park employees reported two people were killed by a rockslide near the intersection of SR 140 and Big Oak Flat Road in Yosemite National Park. | [

1,116,689 | Debris Flow | CALIFORNIA | KERN | 2023-08-20T11:02:00 | 2023-08-20T14:02:00 | A strong surge of moisture associated with Hurricane Hillary pushed northward into central California on August 19. This moisture surge resulted in the development of showers and thunderstorms mainly the San Joaquin Valley during the afternoon and evening hours with the most noticeable impact being outflow wind gusts. Hillary weakened into a Tropical Storm and moved into southern California on August 20 resulting in moderate to heavy rainfall across the mountains and deserts of Kern County with several stations picking up between 3 and 5 inches of rainfall with a few stations receiving more than 5.5 inches of rainfall. Much of the Sierra Nevada south of Kings Canyon picked up between 1 and 3 inches of rainfall while the south San Joaquin Valley measured between a half inch and an inch. Further north, rainfall amounts were lower, but many new daily rainfall records were set for August 20. Numerous reports of flash flooding and road closures were observed in Kern County during the afternoon of August 20 through the early morning of August 21. The rains dissipated during the morning of August 21, but an offshore trough provided for enough instability for thunderstorms to break out over the area during the afternoon of August 21 which produced locally heavy rainfall. The trough lifted northeast on August 22 resulting in the moisture being pushed out of our area and drier conditions prevailed for the remainder of the week. California Highway Patrol reported a large rock on Interstate 5 south of Lebec. | [

932,435 | Debris Flow | CALIFORNIA | MONTEREY | 2021-01-27T05:30:00 | 2021-01-27T06:30:00 | A plume of moisture from the tropical Pacific brought an Atmospheric River to the Bay Area January 26th-29th. This system generated heavy rain rates causing flooding and debris flows over area burn scars as well as 15 to 20 inches of rain in the Santa Lucia Mountains. Mudflows near the River Fire burn scar in Monterey County caused damage to homes, covered roadways, and trapped animals at local ranches. Debris flows near the Dolan Fire burn scar caused an entire section of Highway 1 near Rat Creek to collapse into the Pacific Ocean. This was an unusually cold system for an Atmospheric River resulting in lower snow levels and allowing for accumulating snow as low as 1300 feet in elevation. Additionally, strong south to southeast winds gusted to 60-70 mph across area peaks with Mt Diablo reaching 80 mph. Valley locations were gusting up to 40 mph. Numerous trees fell across the region including into homes and onto cars. Multiple power outages were also reported. It is estimated that the storm caused millions of dollars in damage across Santa Cruz County https://www.ksbw.com/article/emergency-declaration-made-in-santa-cruz-county-for-millions-in-damages/35400060.

This system had a deep fetch of tropical moisture associated with it which resulted in a period of moderate to heavy precipitation along with widespread flooding across much of the area on December 31. Numerous reports of flooding and debris flows were reported by law enforcement with several roads being briefly closed as a result of flooding. The system also produced strong wind gusts across the area between the afternoon of December 30 and the morning of January 1 with several stations in the West Side Hills and Tehachapi Mountains reporting gusts exceeding 60 mph. Several stations in the Sierra Nevada below 7500 feet picked up between 4 and 7 inches of rainfall while the adjacent foothills picked up 2 to 4 inches of rainfall. Rain shadowing effects limited precipitation in the San Joaquin Valley to between half an inch and an inch of rain at most locations while many stations in the Tehachapi Mountains also picked up between half an inch and an inch of rain. Several higher elevations SNOTEL stations picked up 18 to 30 inches of new snowfall adding to the heavy snowpack which had already accumulated earlier in December. California Highway Patrol reported a lot of rocks and mud in the roadway on SR 216 at Dry Creek. | [

This event brought in very high amounts of moisture, winds and very warm temps through September 27th. These warm temps rose the freezing levels to be above 9 thousand feet to increase the amount of melt from glacier in headwaters of the Taiya River. Rain amounts from this event ranged from 3 to 5 inches in 36 hours. The heavy rain and high freezing levels produced significant amounts of runoff to cause moderate flood along the Taiya River near Skagway in Dyea and around the Jordan Creek area near Juneau from mid morning on September 26th through the morning of September 27th. ||As the front moved through the area there was a wind shift in the afternoon hours of September 26th and with the ground very wet from the heavy rain caused a tree to fall which triggered a shallow landslide in downtown Juneau to damaged 3 homes. The heavy rain also triggered a landslide near mile marker 26 along the Haines Highway Monday afternoon and 2 near mile marker 31 along Glacier Highway in Juneau one around 1700AKST and then again in the early morning of September 27th. During the early morning hours of September 26th a large landslide came down along the Haines Highway around 23 mile and blocked the highway. AKDOT was on site by day break to assess the situation and begin to clear the material. The highway was reopened by the afternoon. Six hour rainfall amounts ranged from 0.50 to as much as 1.75 at higher elevation. This is after the area had been experiencing heavy rainfall. | [

909,901 | Flash Flood | LOUISIANA | CADDO | 2020-08-27T10:00:00 | 2020-08-27T11:15:00 | Major Hurricane Laura tracked north northwest across the Central and Northern Gulf of Mexico from the Central Carribean Sea near Cuba, making landfall in Southwest Louisiana near Cameron around 1 am on August 27th as a strong Category 4 hurricane with maximum sustained winds near 150 mph, and a minimum central pressure of 938 mb. Laura remained a hurricane as it tracked north across Southwest and Central Louisiana and into Natchitoches Parish, before weakening to a tropical storm as it moved northeast across North-central Louisiana and South-central Arkansas. A combination of observed and estimated wind gusts ranged from 50-90+ mph, resulting in numerous to widespread downed trees and power lines over these areas throughout the morning and early afternoon, before winds weakened by mid-afternoon with the departure of Laura into Southern Arkansas. Widespread rainfall amounts of 2-6 inches was observed across North Louisiana, with higher amounts of 6-8+ inches recorded across Southern and Western DeSoto, Sabine, Natchitoches, Western Grant, Winn, Jackson, and Eastern Bienville Parishes. Flooding was mostly confined to Natchitoches and Western Caddo Parishes.||Here are the peak wind gusts at various automated stations across the affected areas of North Louisiana: ||Gum Springs RAWS (Winn Parish), 70 mph (Incomplete data due to power failure) |Natchitoches (Natchitoches Parish), 66 mph (Incomplete data due to power failure)|Shreveport Regional Airport (Caddo Parish), 66 mph |Monroe (Ouachita Parish), 62 mph (Incomplete data due to power failure)|Ouachita Christian School (Ouachita Parish), 62 mph |Benton (Bossier Parish), 61 mph|Mansfield (DeSoto Parish), 59 mph |Shreveport Downtown Airport (Caddo Parish), 58 mph|Red River Research Station (Bossier Parish), 58 mph |Catahoula RAWS (Grant Parish), 56 mph (Incomplete data due to power failure)|The University of Louisiana-Monroe, Hanna Hall (Ouachita Parish), 55 mph |Bossier City, Barksdale Air Force Base (Bossier Parish), 55 mph |South Bossier City, LSU Research Station (Bossier Parish), 48 mph|Ruston (Lincoln Parish), 44 mph (Incomplete data due to power failure) ||During the peak of the widespread power outages shortly after Laura's center of circulation exited North Louisiana during the afternoon of the 27th, 136,000 customers were without power in Western Louisiana, East Texas, and Southwest Arkansas, with nearly 108,000 Entergy customers without power across North-central and Northeast Louisiana, as well as South-central Arkansas.||Preliminary damage estimates from the LSU AgCenter indicate that Hurricane Laura caused $525.4 million in damage to Louisiana farmers, and $1.1 billion to the Louisiana timber industry, more than Hurricanes Katrina and Rita combined in 2005. Grant Parish alone was 4th in the state with the amount of timber lost, with over $111 million. Entergy reported that Hurricane Laura caused $1.7 billion to its infrastructure throughout Louisiana. ||Here are the known damage across various parishes affected in North Louisiana: ||Caddo Parish: Numerous trees and power lines down parishwide, including the city of Shreveport. Homes were sporadically damaged across the parish from fallen trees. A large tree fell on a home on Ratcliff Drive in Shreveport, causing extensive structural damage and injuring one person.

Some trees fell on homes in West Monroe and Monroe. The awning at a Chevron gas station in West Monroe was significantly damaged. The damage and power outages led to the cancellation of classes at the University of Louisiana-Monroe for the following week. ||Jackson Parish: Numerous trees were down across the parish, particularly across the southern portion of the parish and to exposed areas along Caney Creek Reservoir in the Jimmie Davis State Park. One tree fell into a single wide mobile home and killed a 51 year old male on Ayres Loop in Jonesboro. The sustained winds bent trees and the brief stronger winds gusts helped contribute to the tree snaps in the Jimmie Davis State Park. The tree falls generally ranged from the southwest to west-southwest. Power outages to nearly 100 percent of parish residents. ||Caldwell Parish: Multiple trees and power lines down on Highway 4 West between Wiles Road and Mount Pleasant Road, as well as others areas throughout the parish. ||Winn Parish: Scattered to widespread tree damage across the parish, particularly across the central and western portions of the parish which were impacted by the eastern edge of Laura's center of circulation.

The most concentrated tree damage (and related home and electrical infrastructure damage related to tree fall) occurred between Dry Prong and the Bentley community along Rob Wallace Road. The tree fall ranged from the west through the northeast, suggesting wind damage was occurring both preceding and in wake of Laura's center of circulation. Power outages to nearly 100 percent of parish residents. ||Natchitoches Parish:Scattered to widespread tree damage in the parish, particularly across the southern and eastern portions of the parish which were impacted by the northern and eastern edge of Laura's center of circulation. The most concentrated damage observed was in Cloutierville and Natchez and locations between these communities along the Cane River. In Cloutierville, hardwood and softwood trees were snapped and uprooted around many homes. In Natchez, most trees were uprooted, while some were snapped. The roof was blown off of the Police Dept. in Robeline. Interstate 49 was closed near Highway 174 due to a fallen tree across the interstate at mile marker 154. Power outages to nearly 100 percent of parish residents. Widespread flooding was reported across much of the parish. Widespread flooding was observed across many areas of the parish. ||Sabine Parish: Scattered tree damage across most of the parish with more widespread damage across the southeastern corner of the parish and exposed areas to the open waters of Toledo Bend Reservoir in the far southwest part of the parish. Damage included snapped trees, roof damage to an apartment complex, and clusters of uprooted trees. The tree fall throughout the parish ranged from south to south-southeast. Power outages to nearly 100 percent of parish residents. I-20 at Exit 5 was covered in high water. | [

1,000,078 | Debris Flow | CALIFORNIA | SANTA CRUZ | 2021-12-13T10:40:00 | 2021-12-13T11:40:00 | A low pressure system descended from the Gulf of Alaska southward along the entire Pacific Coast and tapped into sub-tropical moisture originating from the Central Pacific to drop heavy rain throughout the state. A stalled frontal boundary over the Santa Cruz Mountains along with strong southerly winds from a coastal low-level jet, enhanced orographic rainfall over this region, leading to rainfall totals over a 2 day period (Dec 12th-13th) of up to ten inches in the coastal mountains. The stalled boundary was reinvigorated by a secondary boundary bringing in a cold unstable airmass that set off convective showers and lowered snow levels below 2000 ft. A wind advisory, later upgraded to a high wind warning was issued for the southern half of the region from the SF Peninsula down to the Big Sur Coast including the inland zones due to the coastal jet bringing sustained winds up to 40 mph with gusts up to 55 mph. A high surf advisory was issued for the entire coast due to the arrival of a strong NW swell train, along with Gale Warning throughout the coastal waters. A flash flood watch was issued for the Santa Lucia Mountains and Dolan Burn Scar area, where up to 12 inches of rain fell. Video, https://www.youtube.com/watch?v=4LFZJqrqidw, of rapid debris flow in Boulder Creek area, 200 ft from where Foreman Creek crosses under SR236. Creek runs through part of the CZU burn scar area. | [

1,062,419 | Debris Flow | CALIFORNIA | KERN | 2022-12-31T21:29:00 | 2022-12-31T23:59:00 | A large upper trough moved slowly through California on December 30 and 31. This system had a deep fetch of tropical moisture associated with it which resulted in a period of moderate to heavy precipitation along with widespread flooding across much of the area on December 31. Numerous reports of flooding and debris flows were reported by law enforcement with several roads being briefly closed as a result of flooding. The system also produced strong wind gusts across the area between the afternoon of December 30 and the morning of January 1 with several stations in the West Side Hills and Tehachapi Mountains reporting gusts exceeding 60 mph. Several stations in the Sierra Nevada below 7500 feet picked up between 4 and 7 inches of rainfall while the adjacent foothills picked up 2 to 4 inches of rainfall. Rain shadowing effects limited precipitation in the San Joaquin Valley to between half an inch and an inch of rain at most locations while many stations in the Tehachapi Mountains also picked up between half an inch and an inch of rain. Several higher elevations SNOTEL stations picked up 18 to 30 inches of new snowfall adding to the heavy snowpack which had already accumulated earlier in December. California Highway Patrol reported a mudslide at the intersection of Lebec Rd. and Landslide Rd. | [

1,065,767 | Debris Flow | CALIFORNIA | KERN | 2023-01-14T15:53:00 | 2023-01-14T17:53:00 | Another strong low pressure system impacted central California as it moved eastward across northern California on January 14. The deeper moisture associated with this system arrived during the evening on January 13 and the precipitation continued across the area until the evening of January 14 when it finally tapered off. Strong upper jet dynamics associated with this system produced a period of widespread heavy precipitation across the area during the afternoon of January 14. Between 2 and 4 inches of liquid precipitation fell over the Sierra Nevada while 1.5 to 3 inches of rain fell over the adjacent foothills. Most of the San Joaquin Valley only picked up between a quarter of an inch and three quarters of an inch of rain due to rain shadowing effects. Several higher elevation SNOTEL stations picked up between 1.5 and 3 feet of new snowfall above 6000 feet with a few inches of snow falling as low as 4500 feet in the Sierra Nevada as cooler air pushed into the area during the evening of January 14. The main impacts from this system came from flooding which was a result of significant rainfall taking place over already saturated soil and continued runoff from previous storms. California Highway Patrol reported the roadway washed out with several vehicles stuck on SR 33 between Brown Material Rd. and SR 46. | [

962,305 | Flash Flood | ARKANSAS | PULASKI | 2021-06-06T19:00:00 | 2021-06-06T22:00:00 | Hit and miss thunderstorms ramped up on the 6th. Two to more than three inches of rain was measured at Cane Creek State Park (Lincoln County), Fordyce (Dallas County), Monticello (Drew County), Nashville (Howard County), and Pine Bluff (Jefferson County). Several roads were under water between Avilla (Saline County) and Ferndale (Pulaski County), and also at Monticello (Drew County).||During the predawn hours of the 7th, thunderstorm winds downed a tree on Highway 53 just south of Gurdon (Clark County). This caused a log truck to overturn. In the afternoon, more trees were toppled in Camden and East Camden (both in Ouachita County). A chapel roof was damaged just southwest of Cummins (Lincoln County), and part of a roof was blown off close to Sorrells (Jefferson County).||At least a dozen Tornado Warnings were issued in portions of Calhoun, Clark, Cleveland, Dallas, Garland, Hot Spring, Montgomery, Ouachita, and Pike Counties. A funnel cloud was spotted by law enforcement at Gum Springs (Clark County). There was a brief tornado reported (rated EFU, where U is unknown because there was no damage to evaluate) to the west of Calion (Union County) at 426 pm CDT. The tornado apparently did little more than kick up some dust.||On the 8th, there was a life threatening deluge in southeast Arkansas. Showers and thunderstorms became widespread, and moved over the same areas for several hours.||Too much rain flooded roads at Star City and Varner (both in Lincoln County), Pine Bluff (Jefferson County), Stuttgart (Arkansas County), and also at Dumas and McGehee (both in Desha County). Water got into many homes. Crop and road damage (washouts) was reported in Bradley County. A creek was out of its banks just southeast of Timber Ridge (Pulaski County).||There was high water along Highway 114 between Calmer and Rison (both in Cleveland County), Highway 425 near Yorktown (Lincoln County), Highway 293 east of Garrett Bridge (Lincoln County), Highway 46 not far from Ebb (Grant County), Highway 276 on the south side of Stuttgart (Arkansas County), and Highway 1 at Kelso (Desha County). These highways were eventually closed temporarily.||The situation was the most serious in Desha and Drew Counties, and a Flash Flood Emergency was issued for the communities of Dumas, Pickens, Rohwer (all in Desha County), and Winchester (Drew County) at 1142 am CDT on the 8th. Radar estimated 10 to more than 15 inches of rain, and there was water everywhere. Some folks indicated (through social media) they had never witnessed flooding of this magnitude.||From an historic perspective, Rohwer (Desha County) received 9.25 inches of rain in the twenty four hour period ending at 700 am CDT on the 8th. This was the most rain in one day at the site, and the fourth largest one day total across the state in June. If that was not enough, 9.97 inches of liquid was measured the next day! Adding the numbers, the whopping 19.22 inches on the 8th/9th was the second biggest two day amount in Arkansas. It was just behind the 21.45 inches at Danville (Yell County) on December 3-4, 1982.||Relentless cloudbursts continued to start the 9th in eastern Arkansas. A rain gauge near DeValls Bluff (Prairie County) completely filled (to six inches) between 400 am and 700 am CST. Buildings were flooded and cars were stalled in Clarendon (Monroe County). It was the same story in Humnoke (Lonoke County), and sandbags were ordered to stop the water.||It was just getting worse in Stuttgart (Arkansas County), with one picture showing more water in a home than ever before (in the life of the photographer/42 years). That claim was likely true because the 7.50 inches of rain that caused the problem easily surpassed the previous one day June record of 4.07 inches on the 29th in 1939. At least fifteen homes were impacted by flooding at Altheimer (Jefferson County). Highway 302 from Highway 17 to Highway 79 was shut down in Monroe County, as was Highway 15 near Sherrill (Jefferson County), Highway 33 east of Tollville (Prairie County), and Highways 85 and 318 near Oneida (Phillips County).||As the weather calmed down in the east by the afternoon of the 9th, temperatures warmed well into the 80s to around 90 degrees across the northern and central counties. Heating and lots of humidity were enough to fuel isolated strong to severe storms toward evening.||Just after 700 pm CDT, a video showed a tornado (rated EFU) that lasted two minutes in a field near Blakemore (Lonoke County). Between 700 pm and 800 pm CDT, there was quarter size hail just east of College Station (Pulaski County). Little Rock (Pulaski County) got a quick 1.10 inches of rain. Trees were blown down at Cave City (Sharp County). At 805 pm CDT, there was a brief weak tornado (rated EF0) a few miles southeast of England (Lonoke County).||The focus shifted back to the southeast early on the 10th. You guessed it...the sky was falling again. Rain plus runoff from the soaking on the 8th/9th in northern and central Desha County inundated farms toward Halley (Desha County) in the south. At 200 pm CDT, an irrigation canal east of Pickens (Desha County) was breached, and adjacent farmland became a lake. The canal was patched by evening. At Florence (Drew County), residents were forced to use boats to get around. Water threatened structures at Dermott and Eudora (both in Chicot County), and sandbagging was in progress. It was clear that assistance was needed, and Arkansas Governor Asa Hutchinson declared a state of emergency. ||All was quiet quiet in Little Rock (Pulaski County) on the 10th, and the sun was out. For the first time in 2021, the temperature touched 90 degrees (the high was 92 degrees), and it was three weeks late (it normally happens by May 18th). Toward evening, it got loud toward Pinnacle Mountain (Pulaski County). A severe storm pumped out quarter size hail, winds strong enough to push over a few trees, and up to six inches of rain in less than two hours. The terrain accentuated the flow of water across roads and into neighborhoods. A picture on social media showed water moving across a neighborhood road in Ferndale. | [

1,087,202 | Flash Flood | ARKANSAS | SCOTT | 2023-03-02T21:06:00 | 2023-03-03T00:06:00 | March certainly roared in like a lion across the state with back to back severe weather events on March 1st and 2nd into the 3rd. Storms on these days led to a few tornadoes as well as hail as large as 3 inches in diameter. Very heavy rainfall was noted across the area as well which led to flash flooding and widespread river flooding. One fatality occurred because of the flooding in Scott County on March 2nd. ||As the air heated up, and the atmosphere destabilized, severe thunderstorms were triggered by the front during the late afternoon and evening. The storms produced very large hail, and also caused spotty wind damage. Hail slightly larger than baseballs was reported at Woodlawn (Cleveland County), with ping pong ball size stones near Benton (Saline County) and west of Stuttgart (Arkansas County), and half dollar size hail a few miles north of Norman (Montgomery County). At Rison (Cleveland County), wind gusts up to 85 mph ripped the roof off of a church and a strip mall. Part of a brick facade was removed from latter structure. Trees were also toppled, with one tree blocking Highway 79.||The front on the 1st advanced toward the Louisiana border and stalled. The front was followed by cooler air. On the 2nd, all eyes were on a powerful storm system in the southern Rockies. In response to the approaching system, the front began lifting back to the north. By 400 pm CST, the front cleared the southern counties, and temperatures warmed into the 70s. However, readings north of Little Rock (Pulaski County) were mostly in the 50s.||As the system neared in the late afternoon, it interacted with the front and round two of thunderstorms commenced from central/northeast Texas into southeast Oklahoma. Eventually, storms congealed into a line and raced toward Arkansas. As the storms progressed into the state after dark, it was clear that severe weather (including tornadoes) was most likely south of the front (in mild air), with mainly heavy to excessive rain farther north (where cooler conditions existed).||Between 900 pm and 1000 pm CST, trees were pushed over by straight-line winds west of Y City (Scott County). About this time, rain was coming down in buckets across Scott and Yell Counties, and numerous roads were flooded/about to flood. At Boles (Scott County), there was a report of people surrounded by water and unable to leave their home.||As the night wore on, the Poteau River at Cauthron (Scott County) rose 15 feet in a hurry. The same swollen river swept a pickup truck off of Highway 80 on the east side of Waldron (Scott County). Tragically, the driver (a grandfather trying to visit his grandson) drowned. A traffic camera (provided by the Arkansas Department of Transportation) along Highway 71 south of Boles (Scott County) showed the Fourche La Fave River almost as high as the bridge over the tributary. Eventually, the pavement was inundated and became impassible. As roads turned into lakes, a vehicle stalled at Parks (Scott County), and two individuals were rescued. Similar rescues were ongoing in Yell County, and one person was transported from Corinth to a hospital in Danville (both in Yell County).||Shortly before 1100 pm CST, a tornado (rated EF2) was spawned just to the north of Kirby (Pike County). A few mobile homes were heavily damaged (resulting in three injuries). One mobile home was rolled and obliterated. Miraculously, two of the four occupants only had minor injuries. Several homes suffered roof damage, and two chicken houses were destroyed.||A couple of hours later, thunderstorm winds downed/snapped trees along Highway 229 about four miles north of Carthage (Dallas County). A few minutes before 200 am CST on the 3rd, a brief weak tornado (rated EF0) touched down in open fields east of Altheimer (Jefferson County). The tornado took out some trees along Highway 58.||Elsewhere, a weak tornado (rated EF1) was identified west of Fouke (Miller County). More trees were blown down southwest of Hope (Hempstead County) and northeast of Nashville (Howard County). Wind gusts as high as 70 to 80 mph roughed up barns, outbuildings, and signs between Damascus (Faulkner/Van Buren Counties) and Rose Bud (White County). A recreational vehicle was crushed by a fallen tree at Enola (Faulkner County).||As far as rain, there was a lot of it. Two to more than four inches of rain was common across the northern half of the state in the twenty four hour period ending at 600 am CST on the 3rd. Waldron (Scott County) had 4.90 inches of precipitation, with 4.88 inches at Blue Mountain Dam (Yell County), 4.72 inches at Danville (Yell County), 4.45 inches at Abbott (Scott County), 4.22 inches at Dardanelle (Yell County), 3.87 inches at Booneville (Logan County), 3.70 inches at Mountain View (Stone County), 3.65 inches at Gilbert (Searcy County), 3.57 inches at Calico Rock (Izard County), 3.54 inches at Mena (Polk County), 3.50 inches at Damascus (Van Buren County), 3.47 inches at Marshall (Searcy County) and Morrilton (Conway County), and 3.40 inches at Conway (Faulkner County).||Given so much rain, there was a landslide near the intersection of Highways 103 and 215 west of Oark (Johnson County). Before dawn on the 3rd, the Spring River at Hardy (Sharp County) went up six feet in two hours, was in danger of reaching a level of 14 feet (four feet above the flood stage). As a precaution, folks in homes near the river were asked to evacuate. ||The rain on the 2nd/early on the 3rd was in addition to the precipitation that fell on the 1st, especially from central into southeast Arkansas. In this part of the state, two or more inches of liquid was measured in places. This included Cane Creek State Park (Lincoln County), Keo (Lonoke County), Marianna (Lee County), Pine Bluff (Jefferson County), Sheridan (Grant County), and Stuttgart (Arkansas County).||On the 3rd, there was moderate to major flooding on the Petit Jean River, and minor to moderate flooding on the Black, Cache, Fourche La Fave, Little Red, Ouachita, Saline, Spring, and White Rivers. Concerns were growing that river levels could go even higher if a wet pattern continued into early spring. Numerous roads have been flooded throughout Scott County. However, in Boles there was a report that some people were isolated in their home due to rising flood waters. A man was found drowned the next day when flood waters began to recede, so the timing of death is uncertain. His age is unknown, but he was likely an older adult as he was described as a grandfather. He likely drove into floodwaters and got washed off the road sometime between the night of the 2nd and the morning of the 3rd. | [

Two to more than three inches of rain was measured at Cane Creek State Park (Lincoln County), Fordyce (Dallas County), Monticello (Drew County), Nashville (Howard County), and Pine Bluff (Jefferson County). Several roads were under water between Avilla (Saline County) and Ferndale (Pulaski County), and also at Monticello (Drew County).||During the predawn hours of the 7th, thunderstorm winds downed a tree on Highway 53 just south of Gurdon (Clark County). This caused a log truck to overturn. In the afternoon, more trees were toppled in Camden and East Camden (both in Ouachita County). A chapel roof was damaged just southwest of Cummins (Lincoln County), and part of a roof was blown off close to Sorrells (Jefferson County).||At least a dozen Tornado Warnings were issued in portions of Calhoun, Clark, Cleveland, Dallas, Garland, Hot Spring, Montgomery, Ouachita, and Pike Counties. A funnel cloud was spotted by law enforcement at Gum Springs (Clark County). There was a brief tornado reported (rated EFU, where U is unknown because there was no damage to evaluate) to the west of Calion (Union County) at 426 pm CDT. The tornado apparently did little more than kick up some dust.||On the 8th, there was a life threatening deluge in southeast Arkansas. Showers and thunderstorms became widespread, and moved over the same areas for several hours.||Too much rain flooded roads at Star City and Varner (both in Lincoln County), Pine Bluff (Jefferson County), Stuttgart (Arkansas County), and also at Dumas and McGehee (both in Desha County). Water got into many homes. Crop and road damage (washouts) was reported in Bradley County. A creek was out of its banks just southeast of Timber Ridge (Pulaski County).||There was high water along Highway 114 between Calmer and Rison (both in Cleveland County), Highway 425 near Yorktown (Lincoln County), Highway 293 east of Garrett Bridge (Lincoln County), Highway 46 not far from Ebb (Grant County), Highway 276 on the south side of Stuttgart (Arkansas County), and Highway 1 at Kelso (Desha County). These highways were eventually closed temporarily.||The situation was the most serious in Desha and Drew Counties, and a Flash Flood Emergency was issued for the communities of Dumas, Pickens, Rohwer (all in Desha County), and Winchester (Drew County) at 1142 am CDT on the 8th. Radar estimated 10 to more than 15 inches of rain, and there was water everywhere. Some folks indicated (through social media) they had never witnessed flooding of this magnitude.||From an historic perspective, Rohwer (Desha County) received 9.25 inches of rain in the twenty four hour period ending at 700 am CDT on the 8th. This was the most rain in one day at the site, and the fourth largest one day total across the state in June. If that was not enough, 9.97 inches of liquid was measured the next day! Adding the numbers, the whopping 19.22 inches on the 8th/9th was the second biggest two day amount in Arkansas. It was just behind the 21.45 inches at Danville (Yell County) on December 3-4, 1982.||Relentless cloudbursts continued to start the 9th in eastern Arkansas. A rain gauge near DeValls Bluff (Prairie County) completely filled (to six inches) between 400 am and 700 am CST. Buildings were flooded and cars were stalled in Clarendon (Monroe County). It was the same story in Humnoke (Lonoke County), and sandbags were ordered to stop the water.||It was just getting worse in Stuttgart (Arkansas County), with one picture showing more water in a home than ever before (in the life of the photographer/42 years). That claim was likely true because the 7.50 inches of rain that caused the problem easily surpassed the previous one day June record of 4.07 inches on the 29th in 1939. At least fifteen homes were impacted by flooding at Altheimer (Jefferson County). Highway 302 from Highway 17 to Highway 79 was shut down in Monroe County, as was Highway 15 near Sherrill (Jefferson County), Highway 33 east of Tollville (Prairie County), and Highways 85 and 318 near Oneida (Phillips County).||As the weather calmed down in the east by the afternoon of the 9th, temperatures warmed well into the 80s to around 90 degrees across the northern and central counties. Heating and lots of humidity were enough to fuel isolated strong to severe storms toward evening.||Just after 700 pm CDT, a video showed a tornado (rated EFU) that lasted two minutes in a field near Blakemore (Lonoke County). Between 700 pm and 800 pm CDT, there was quarter size hail just east of College Station (Pulaski County). Little Rock (Pulaski County) got a quick 1.10 inches of rain. Trees were blown down at Cave City (Sharp County). At 805 pm CDT, there was a brief weak tornado (rated EF0) a few miles southeast of England (Lonoke County).||The focus shifted back to the southeast early on the 10th. You guessed it...the sky was falling again. Rain plus runoff from the soaking on the 8th/9th in northern and central Desha County inundated farms toward Halley (Desha County) in the south. At 200 pm CDT, an irrigation canal east of Pickens (Desha County) was breached, and adjacent farmland became a lake. The canal was patched by evening. At Florence (Drew County), residents were forced to use boats to get around. Water threatened structures at Dermott and Eudora (both in Chicot County), and sandbagging was in progress. It was clear that assistance was needed, and Arkansas Governor Asa Hutchinson declared a state of emergency. ||All was quiet quiet in Little Rock (Pulaski County) on the 10th, and the sun was out. For the first time in 2021, the temperature touched 90 degrees (the high was 92 degrees), and it was three weeks late (it normally happens by May 18th). Toward evening, it got loud toward Pinnacle Mountain (Pulaski County). A severe storm pumped out quarter size hail, winds strong enough to push over a few trees, and up to six inches of rain in less than two hours. The terrain accentuated the flow of water across roads and into neighborhoods. Video showed flash flooding near Cantrell Rd. and Chenal Parkway. | [

885,254 | Flash Flood | ARKANSAS | SCOTT | 2020-05-15T15:30:00 | 2020-05-15T18:30:00 | On the 15th, the focus was mainly to the west of Arkansas. Showers and thunderstorms became widespread across the southern Plains surrounding a storm system wobbling this way from the southwest. Some of the fireworks managed to work into western sections of the state during the afternoon and evening.||Rain was very heavy in places, with many streets covered by water in and around Waldron (Scott County). Strong to damaging thunderstorm winds toppled trees a few miles northwest of Murfreesboro (Pike County). There was quarter size hail at Bismarck (Hot Spring County). ||In the northwest, it rained at Harrison (Boone County). As rain departed to the southeast between 300 pm and 500 pm CST, the pressure dropped quickly. Temperatures warmed up and the air dried out. This was a sure sign that a small area of low pressure was forming in the wake of the exiting precipitation (a wake low). Winds kicked up and gusted as high as 50 mph. ||On the 16th, conditions were expected to go downhill locally. Widespread precipitation was in the forecast, especially in central and western Arkansas.||Given plenty of water to wring out of the clouds, flash flooding was a concern. Between 500 pm and 1000 pm CST, high water problems were realized as a deluge unfolded.|Water flowed across roads in Conway and Greenbrier (both in Faulkner County) and surrounding areas. Barricades had to be used in some cases. It was the same story at Shirley (Van Buren County) and south of Mount Ida (Montgomery County), and creeks were out of their banks. Five miles west and southwest of Arkadelphia (Clark County), Highways 8 and 26 were impassible due to flooding. Highway 71 at Y City (Scott County) was closed for the same reason.||There were quick rises on the Buffalo, Eleven Point, Fourche La Fave, Little Missouri, Petit Jean, Saline, and Spring Rivers, with minor flooding occurring in spots. The Ouachita River also came up fast, and this was due to the rain and releases at Remmel Dam. There was enough water to keep the Black, Cache, and lower White Rivers elevated, which was the norm for much of the year up to this point.||Storms in southeast Arkansas were very isolated, but popped up in a hurry where they managed to develop. Weak rotation in the clouds was stretched as clouds mushroomed. Rotation tightened after being extended leading to a brief landspout just north of Sherrill (Jefferson County) not long after 530 pm CST. This was unlike most springtime tornadoes that are usually associated with mesocyclones (strong persistent circulations that extend thousands of feet into the atmosphere).||The turning motion around the incoming system increased chances of isolated tornadoes southwest of Little Rock (Pulaski County). Numerous Tornado Warnings were issued in the far southwest, and there was damage in places.||Other spotty wind damage was reported. Metal roofing was removed from boat docks and at least a dozen trees were uprooted at a resort just northwest of Crystal Springs (Garland County). Trees and power lines were downed at Leola (Grant County).||The system gradually weakened once it arrived with a cold front on the 17th. Precipitation became more scattered and was not as heavy.||Three to more than five inches of rain dumped at quite a few locations in the western half of the state in the seventy two hour period ending at 600 pm CST on the 17th. This included Alexander (Pulaski/Saline Counties), Benton (Saline County), Booneville (Logan County), Conway (Faulkner County), Damascus (Van Buren County), DeGray Lake State Park (Clark/Hot Spring Counties), Delight (Pike County), Fairbanks (Van Buren County), Fordyce (Dallas County), Harrison (Boone County), Hot Springs (Garland County), Marshall (Searcy County), Mena (Polk County), Menifee (Conway County), Mountain Home (Baxter County), Mount Ida (Montgomery County), Murfreesboro (Pike County), and Waldron (Scott County).||For the month (through the 17th), there was more than the usual precipitation in central/western Arkansas, and it was drier than normal in the east. Surpluses of liquid were over an inch at Harrison (Boone County). Many roads were covered in water throughout the city and surrounding areas. | [

859,907 | Flash Flood | NEW YORK | HERKIMER | 2019-10-31T21:00:00 | 2019-10-31T23:59:00 | A strengthening low pressure system moving from Ohio to Lake Ontario drew anomalous warmth and moisture northward on Halloween, with temperatures surging into the 60s and 70s over eastern New York and western New England. Showers across the southern Adirondacks and Mohawk Valley became steadier and heavier during the evening ahead of a strong cold front as the low continued to strengthen. Strong winds aloft mixed down to the surface as an intense line of showers developed along the front, resulting in sporadic wind damage and scattered power outages over eastern New York.||A large swath of rainfall totaling 2-5 inches, with isolated areas as high as 7 inches, occurred over the Mohawk Valley and southern Adirondacks, resulting in reports of flash flooding. The runoff caused rapid rises on area creeks and streams, with river gauges reaching record levels along the Mohawk River at Little Falls, the West Canada Creek at Hinckley and Kast Bridge, and the Sacandaga River at Hope. Moderate flooding also occurred on the Hudson River at Fort Edward, Hadley, and North Creek; the Schroon River at Riverbank; and the Mohawk River at Delta Dam. Although river rises and some impacts occurred prior to midnight, the crests occurred on 1 November, and impacts persisted into the first week of November in some areas (see also November StormData). The flooding was extensive over portions of the area, damaging and destroying numerous roads and structures and resulting in water rescues. Between 150 and 200 people were evacuated in Herkimer County. The number of dwellings damaged by the flooding was 344, of which 135 sustained major damage, and 18 were destroyed. There was one fatality as a result of the flooding as a man was swept away by flood waters when he exited his vehicle. ||As a result of the flooding, a major disaster for the state of New York was requested by Governor Cuomo and approved by the President. The monetary damages for public infrastructure requested for the Mohawk Valley and southern Adirondacks totaled around $17 million ($1.2 million for Fulton County, $3.0 million for Hamilton County, $8.8 million for Herkimer County, $0.5 million for Montgomery, $1.6 million for Saratoga, and $1.9 million for Warren). Actual damage amounts were estimated to be even higher by county emergency managers. A state of emergency was declared for Dutchess, Herkimer, Hamilton, Saratoga, and Warren Counties, and boil water notices were issued in Herkimer, Hamilton, and Warren Counties due to floodwater inundation of private and public water systems. The American Red Cross opened shelters to house those displaced by flood damage. ||Other impacts from the flooding and high winds included the cancellation of Amtrak service between Syracuse and Albany due to high water encroaching on train tracks, and portions of the Adirondack Park backcountry becoming impassable due to bridge washouts, high water at stream crossings, and downed trees and debris on trails and at trailheads. Water was flowing over the West Main Street bridge, prompting the village of Frankfort to issue a state of emergency. | [

The American Red Cross opened shelters to house those displaced by flood damage. ||Other impacts from the flooding and high winds included the cancellation of Amtrak service between Syracuse and Albany due to high water encroaching on train tracks, and portions of the Adirondack Park backcountry becoming impassable due to bridge washouts, high water at stream crossings, and downed trees and debris on trails and at trailheads. Route 5 was closed between Newport Road and Millers Grove Road due to flooding. | [

Linking Events to Time Series
The ts_dict_index field in event_report.jsonl contains a list of line indices (0-based) pointing to rows in mmts.jsonl. These identify the weather station time series samples spatially and temporally associated with each event.
import json
with open("mmts.jsonl") as f:
mmts = [json.loads(line) for line in f]
with open("event_report.jsonl") as f:
for line in f:
event = json.loads(line)
related_ts = [mmts[i] for i in event["ts_dict_index"]]
