How Likely Is a Tornado in Putnam County, OH?
Putnam County's tornado history, by the numbers
Putnam County has recorded 28 tornado touches in NOAA's 76-year database, a rate of roughly one every 2.7 years - our Elevated band. Put another way: Putnam County sees more tornado activity than 66% of US counties. Ohio has 88 counties in this dataset; Putnam County ranks 15 of them by frequency.
Beyond the frequency band: violent history
1 tornado touching Putnam County reached violent (EF4-5) strength since 1950. That single fact carries more weight for the shelter decision than the county's overall frequency band.
The dollar figure Putnam County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Ohio has no state rebate program confirmed here; FEMA's underlying 75% cost-share exists nationwide, but applying through a state program is what usually makes it real, and none was found for Ohio this pass.
What a direct hit isn't required for
34,206 people live in Putnam County, and a tornado outbreak's power loss usually reaches far more of Ohio than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What this number is, and is not
One caveat before relying on Putnam County's number: it is county-wide, and it covers about 483 square miles, so a single touch counts the same as one in a county a fraction of that size. Weaker pre-1990s tornadoes are also documented as undercounted in NOAA's own record. Putnam County has about 34,206 residents.
