The NOAA National Centers for Environmental Information (NCEI) Storm Events Database records every significant weather event in the US from 1950 to present — ~2.1M event records, 48 standardized event types (tornado, hurricane, flash flood, hail, winter storm, wildfire, and more), with property damage, crop damage, injuries, fatalities, and county-level geography. Bulk download at ncei.noaa.gov/pub/data/swdi/stormevents/csvfiles/ with annual gzipped CSVs; CDO API at www.ncei.noaa.gov/cdo-web/api/v2/. DAMAGE_PROPERTY field uses K/M/B suffix encoding requiring parsing. NOAA Billion-Dollar Disasters tracker covers 376 events since 1980 totaling $2.6T in CPI-adjusted damages; 2023: 28 events exceeding $1B each — a record. Tornado climatology: ~1,200-1,500 annually, EF0-EF5 scale, 2011 Super Outbreak 362 tornadoes/3 days, Dixie Alley shift. Hurricane damage: Harvey $125B, Ian $112B county-by-county in Storm Events. Flood events: deadliest weather type most years, ~88 fatalities/year average, AHPS stream gauge network. Climate change signal in increasing damage frequency and extreme precipitation. Here is event type taxonomy, data quality caveats, NCEI CDO API, Billion-Dollar Disasters methodology, tornado EF scale, hurricane storm surge vs. wind damage distinction, and a Python DAMAGE_PROPERTY parsing analysis by event type and state.
