Franklin County within Missouri. 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.

The NCEI record lists 882 events for Franklin County, Missouri, between 1950 and 2026; damaging wind account for the largest share.

That is 95.6 events per 100 square miles, in line with the Missouri figure of 106.7, and 83.8 per 10,000 residents against 118.9 statewide.

23 events fall in the 12 months to 30 Jun 2026. NCEI attributes 6 deaths and 121 injuries to events in the county, with property damage estimated at $108M and crop damage at $11K.

FEMA has designated the county in 24 federal disaster declarations since 1953; the most recent is Severe Storms, Straight-Line Winds, Tornadoes, And Wildfires (major disaster, 21 May 2025).

National Flood Insurance Program policyholders in the county filed 1,097 claims since 1978, of which 975 were paid, totalling $32M (about $33K per paid claim). FEMA counts 156 residential flood policies in force.

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

Trend: 456 events in the 20 years to 2025 against 322 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.
