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 400 events for Putnam County, Ohio, between 1950 and 2026; damaging wind account for the largest share.

That is 82.9 events per 100 square miles, below the Ohio figure of 126.7, and 116.6 per 10,000 residents against 44.0 statewide.

7 events fall in the 12 months to 30 Jun 2026. NCEI attributes 4 deaths and 5 injuries to events in the county, with property damage estimated at $12M and crop damage at $610K.

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

Trend: 197 events in the 20 years to 2025 against 163 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.
