Blaine County within Oklahoma. 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 829 storm events in Blaine County, Oklahoma, led by hail.

That is 89.3 events per 100 square miles, below the Oklahoma figure of 120.9, and 968.2 per 10,000 residents against 208.0 statewide.

30 events fall in the 12 months to 30 Jun 2026. NCEI attributes 2 deaths and 23 injuries to events in the county, with property damage estimated at $36M and crop damage at $8.3M.

Trend: 378 events in the 20 years to 2025 against 349 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.
