Fresno County within California. Dots: HailTornadoFloodWind event locations in the kept record. Boundaries: US Census Bureau.

NCEI notes that Storm Data is compiled from a variety of sources including the National Weather Service, other federal, state and local agencies, the media and the public; that property and crop damage figures are estimates; and that some events are recorded by NWS forecast zone rather than by county. FEMA notes that NFIP claim records are redacted and aggregated to protect the privacy of policyholders. NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 1 Oct 2026; NFIP claims as of 8 Sep 2026.

Between 1950 and 2026, NCEI recorded 863 storm events in Fresno County, California, led by floods and flash floods.

That is 14.5 events per 100 square miles, below the California figure of 26.2, and 8.5 per 10,000 residents against 10.4 statewide.

4 events fall in the 12 months to 30 Jun 2026. NCEI attributes 7 deaths and 29 injuries to events in the county, with property damage estimated at $30M and crop damage at $259M.

FEMA has designated the county in 20 federal disaster declarations since 1953; the most recent is Severe Winter Storms, Straight-Line Winds, Flooding, Landslides, And Mudslides (major disaster, 3 Apr 2023).

National Flood Insurance Program policyholders in the county filed 278 claims since 1978, of which 162 were paid, totalling $2.2M (about $14K per paid claim). FEMA counts 921 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively High" and its expected annual loss as "Relatively High" ($557M a year across 18 hazards).

Trend: 636 events in the 20 years to 2025 against 209 in the 20 years before. Reporting practice changed in 1996 and again with automated reports in the 2000s, so decade totals measure the record as much as the weather.
