McLennan 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 1,302 storm events in McLennan County, Texas, led by hail.

That is 125.6 events per 100 square miles, above the Texas figure of 63.3, and 49.5 per 10,000 residents against 56.0 statewide.

36 events fall in the 12 months to 30 Jun 2026. NCEI attributes 129 deaths and 660 injuries to events in the county, with property damage estimated at $78M and crop damage at $1.7M.

FEMA has designated the county in 25 federal disaster declarations since 1953; the most recent is Severe Winter Storms (major disaster, 19 Feb 2021).

National Flood Insurance Program policyholders in the county filed 393 claims since 1978, of which 307 were paid, totalling $6.7M (about $22K per paid claim). FEMA counts 770 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively Moderate" and its expected annual loss as "Relatively Moderate" ($84M a year across 18 hazards).

12 tropical storm or hurricane tracks in the HURDAT2 record passed within 100 miles of the county's centre at tropical-storm strength or more, 1 of them within 50 miles at hurricane strength.

Recorded events in McLennan County by decade and hazard group. HailTornadoFloodWindWinterHeatColdDroughtWildfireLightningFogOther NCEI recorded only tornadoes, hail and thunderstorm wind before 1996.

Trend: 631 events in the 20 years to 2025 against 468 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.
