Bridgedeck — NOAA Storm Events (2000–2023)

Part of the bridgedeck dataset collection for US bridge deck deterioration research.

Overview

County-level severe weather event counts and damage totals for all US counties, 2000–2023. Derived from the NOAA National Centers for Environmental Information (NCEI) Storm Events Database.

Events are grouped into 5 categories relevant to bridge deterioration: flood, wind, hail, winter storms, and tornadoes. Includes single-year counts and 5-year rolling sums to capture cumulative storm exposure.

Schema

One row per (county_fips, year). Primary key: (county_fips, year).

Column	Type	Description
county_fips	str	5-digit FIPS county code (state_fips + county_fips)
year	int	Year (2000–2023)
flood_count	float	Flood, Flash Flood, Heavy Rain, Storm Surge events
wind_count	float	Thunderstorm Wind, High Wind, Hurricane events
hail_count	float	Hail events
winter_count	float	Ice Storm, Blizzard, Winter Storm, Heavy Snow events
tornado_count	float	Tornado, Waterspout events
storm_damage_total_usd	float	Total property damage from all storm events (USD)
storm_damage_max_usd	float	Maximum single-event property damage (USD)
flood_count_5yr_sum	float	5-year rolling sum of flood events
wind_count_5yr_sum	float	5-year rolling sum of wind events
hail_count_5yr_sum	float	5-year rolling sum of hail events
winter_count_5yr_sum	float	5-year rolling sum of winter storm events
tornado_count_5yr_sum	float	5-year rolling sum of tornado events
storm_damage_total_usd_5yr_sum	float	5-year rolling sum of total damage (USD)
storm_damage_max_usd_5yr_sum	float	5-year rolling sum of max single-event damage (USD)

Join Key

Join to NBI bridge data on county_fips = state_code.zfill(2) + county_code.zfill(3).

Processing Notes

• County-level events (CZ_TYPE='C') are joined directly via FIPS code.
• Winter storm events are almost exclusively reported at NWS forecast zone level (CZ_TYPE='Z'). These are expanded to counties using the NWS Zone-County Correlation File (nws_zone_county.dbx), downloaded automatically during ETL.
• 5-year rolling sums use min_periods=3 (NaN for years 2000–2001).
• Property damage strings (e.g. "1.5K", "2M") are parsed to USD floats.
