Cochise County, Arizona

County storm and disaster record · FIPS 04003 · population 125,169 · 6,210 sq mi

NOAA's Storm Events Database holds 1,250 records for Cochise County, Arizona from 1950 through June 30, 2026, on 749 days; the most frequent are drought records (250 records). 634 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 August 6, 1997 flash flood: 6 deaths. FEMA has issued 14 declarations naming the county since 1970, 12 of them for natural hazards; the latest for a natural hazard was “Lizard Fire” on June 11, 2017.

Heat in the 2020-26: 78 records against 20 in the decade before, 78 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 Cochise County days with a record above.
