Scioto County within Ohio. 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 708 storm events in Scioto County, Ohio, led by damaging wind.

That is 116.0 events per 100 square miles, in line with the Ohio figure of 126.7, and 96.5 per 10,000 residents against 44.0 statewide.

10 events fall in the 12 months to 30 Jun 2026. NCEI attributes 12 deaths and 85 injuries to events in the county, with property damage estimated at $26M and crop damage at $60K.

FEMA has designated the county in 18 federal disaster declarations since 1953; the most recent is Covid-19 Pandemic (major disaster, 31 Mar 2020).

National Flood Insurance Program policyholders in the county filed 318 claims since 1978, of which 256 were paid, totalling $2.7M (about $10K per paid claim). FEMA counts 221 residential flood policies in force.

Trend: 485 events in the 20 years to 2025 against 192 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.
