title: US Storm Events - every severe-weather event with damages & casualties (NOAA, 2000→present), cleaned
description: The official U.S. record of severe weather, cleaned into one fat events table: tornadoes, hail, floods, hurricanes, winter storms, heat, wildfire - every event since 2000 with the human and financial toll. NOAA/NCEI ships the Storm Events Database as one gzipped ~50-column CSV per year, with property and crop damage encoded as strings like '1.50M'; we assemble every year, parse the damages to real USD numbers, and keep the fields that matter - timing, state, hazard type, injuries and deaths (direct & indirect), property & crop damage in USD, magnitude, tornado F/EF scale, and a begin geocode. One row per event, keyed by NOAA event id. The open, authoritative alternative to CC-BY-NC EM-DAT. Public domain.
