Sanpete County, Utah

County storm and disaster record · FIPS 49039 · population 28,408 · 1,590 sq mi

NOAA's Storm Events Database holds 989 records for Sanpete County, Utah from 1950 through June 30, 2026, on 639 days; the most frequent are winter storm records (768 records). 942 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 10 declarations naming the county since 1977, 8 of them for natural hazards; the latest for a natural hazard was “Flooding” on December 23, 2023.
