Natural disaster risk in Washington

How disaster-prone is Washington?

Washington (WA) sits at a moderate level of federally recognized natural-disaster risk, with 94 FEMA disaster declarations on record — including 12 Major Disaster declarations (DR) that triggered full federal individual and public assistance. The dominant declaration type is Fire, followed by Flood (4), Severe Storm (3), Biological (1). Declaration counts at the state level reflect the cumulative federal footprint: large multi-county events count once per state, but repeat hazard patterns across decades are visible in the breakdown below.

NOAA's Storm Events Database adds the near-term severe-weather lens. Between 2015 and 2025, Washington recorded 4,604 individual storm events, causing 97 fatalities and 154 injuries, with combined property and crop damage estimated at $3.9B. The most frequent event types in the state are Heavy Snow (1,736 events), High Wind (647 events), Wildfire (337 events). Across the state's 39 analyzed counties, FEMA's National Risk Index flags 5 as high-risk, with an average county composite risk score of 70.0/100.

NFIP claims data is limited or absent for this state in the current extract, which usually indicates low flood-policy penetration rather than zero flood risk. The highest-Expected-Annual-Loss hazard across the state is Earthquake, estimated at $2.5B annually. Drill into individual counties for localized risk, read FEMA's hazard-specific briefings, and review insurance and flood-zone designations — state-level averages can mask sharp county-to-county differences in exposure and resilience.
