Washington County within Utah. Dots: HailTornadoFloodWind event locations in the kept record. Boundaries: US Census Bureau.

NCEI notes that Storm Data is compiled from a variety of sources including the National Weather Service, other federal, state and local agencies, the media and the public; that property and crop damage figures are estimates; and that some events are recorded by NWS forecast zone rather than by county. FEMA notes that NFIP claim records are redacted and aggregated to protect the privacy of policyholders. NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 1 Oct 2026; NFIP claims as of 8 Sep 2026.

The NCEI record lists 426 events for Washington County, Utah, between 1950 and 2026; floods and flash floods account for the largest share.

That is 17.5 events per 100 square miles, in line with the Utah figure of 14.7, and 22.3 per 10,000 residents against 36.2 statewide.

15 events fall in the 12 months to 30 Jun 2026. NCEI attributes 26 deaths and 26 injuries to events in the county, with property damage estimated at $51M and crop damage at $63K.

FEMA has designated the county in 14 federal disaster declarations since 1953; the most recent is Forsyth Fire (fire management assistance, 20 Jun 2025).

National Flood Insurance Program policyholders in the county filed 64 claims since 1978, of which 36 were paid, totalling $1.2M (about $34K per paid claim). FEMA counts 250 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively Moderate" and its expected annual loss as "Relatively Moderate" ($148M a year across 18 hazards).

Recorded events in Washington County by decade and hazard group. HailTornadoFloodWindLightningOther NCEI recorded only tornadoes, hail and thunderstorm wind before 1996.

Trend: 320 events in the 20 years to 2025 against 97 in the 20 years before. Reporting practice changed in 1996 and again with automated reports in the 2000s, so decade totals measure the record as much as the weather.
