Duchesne County, Utah

County storm and disaster record · FIPS 49013 · population 19,596 · 3,236 sq mi

NOAA's Storm Events Database holds 544 records for Duchesne County, Utah from 1950 through June 30, 2026, on 380 days; the most frequent are winter storm records (369 records). 445 of them are forecast-zone records, which the National Weather Service files once per zone: a county covered by several zones receives each one, so a single storm can add several records on the same day.

FEMA has issued 8 declarations naming the county since 1977, 6 of them for natural hazards; the latest for a natural hazard was “Dollar Ridge Fire” on July 2, 2018.

High wind and dust storms in the 2010s: 22 records against 7 in the decade before, 22 of them forecast-zone records. Cells marked z rose mostly through zone records. The local National Weather Service office files these once per forecast zone, so a change in how it draws its zones or splits a storm into records moves this count as much as the weather does; read it beside the Duchesne County days with a record above.
