Cache County, Utah
County storm and disaster record · FIPS 49005 · population 133,078 · 1,165 sq mi
NOAA's Storm Events Database holds 713 records for Cache County, Utah from 1950 through June 30, 2026, on 547 days; the most frequent are winter storm records (482 records). 587 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. The deadliest single record is the January 11, 1997 blizzard, filed for the forecast zone Wasatch Mountains I80 North, which covers the county: 3 deaths. FEMA has issued 7 declarations naming the county since 1977, 5 of them for natural hazards; the latest for a natural hazard was “Severe Winter Storms and Flooding” on April 21, 2017.
