Winter Storm in the United States

How dangerous are Winter Storm events in the U.S.?

NOAA's Storm Events Database has catalogued 37,855 winter storm events across 51 states and territories between 2015 and 2025. The cumulative human toll is 239 fatalities and 656 injuries, and the financial footprint reaches $393.6M in combined property ($391.0M) and crop ($2.5M) damage. On a per-fatality basis this places winter storm events at a very high severity tier relative to other tracked hazard types in the NOAA catalog.

Geographic exposure is heavily concentrated in a handful of high-severity states. The three states absorbing the largest share of events are WY (2,460 events, 1 fatalities), MN (1,943 events, 2 fatalities), MI (1,850 events, 4 fatalities), reflecting both physical geography (coastal exposure, plains corridors, terrain) and dense population sitting directly in harm's way. At the other end, states such as FL, DC, HI report far fewer events, a genuinely rare event outside the leading states, not merely an underreported one.

The year-to-year record shows real volatility around a high baseline. The peak year on record was 2022, logging 7,288 events and $29.0M in property damage in a single calendar year. The most recent year in the dataset is 2025 with 6,021 events recorded. Across the full 11-year window, annual event counts reflect seasonal climate cycles (ENSO phases, active vs. quiet severe-weather years) and long-term shifts tied to a warming climate both help explain the swings.
