Clark County, Nevada
County storm and disaster record · FIPS 32003 · population 2,260,510 · 7,892 sq mi
NOAA's Storm Events Database holds 2,054 records for Clark County, Nevada from 1950 through June 30, 2026, on 1,103 days; the most frequent are high wind and dust records (519 records). 1,117 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 July 3, 2024 excessive heat, filed for the forecast zone Las Vegas Valley, which covers the county: 42 deaths. FEMA has issued 14 declarations naming the county since 1981, 12 of them for natural hazards; the latest for a natural hazard was “Carpenter 1 Fire” on July 5, 2013.

Heat in the 2010s: 152 records against 33 in the decade before, 152 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 Clark County days with a record above.
