Blanco County within Texas. 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 392 storm events in Blanco County, Texas, led by hail.

That is 55.3 events per 100 square miles, in line with the Texas figure of 63.3, and 329.8 per 10,000 residents against 56.0 statewide.

15 events fall in the 12 months to 30 Jun 2026. NCEI attributes 5 deaths and 14 injuries to events in the county, with property damage estimated at $61M and crop damage at $220K.

FEMA has designated the county in 21 federal disaster declarations since 1953; the most recent is Flooding (emergency, 18 Jul 2026).

National Flood Insurance Program policyholders in the county filed 43 claims since 1978, of which 32 were paid, totalling $2.5M (about $78K per paid claim). FEMA counts 84 residential flood policies in force.

Trend: 223 events in the 20 years to 2025 against 118 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.
