How Likely Is a Tornado in Clinton County, OH?
Clinton County, OH: what NOAA's tornado record says
Clinton County has recorded 36 tornado touches in NOAA's 76-year database, a rate of roughly one every 2.1 years - our Elevated band. Put another way: Clinton County sees more tornado activity than 76% of US counties. Within Ohio alone, Clinton County ranks 4 of 88 counties for tornado frequency.
Beyond the frequency band: violent history
1 tornado touching Clinton 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 Clinton 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
Tornado outbreaks routinely knock out power across Ohio for days, separately from any single house getting hit. A portable battery bank keeps a fridge, phone chargers and a radio running through that gap - cheaper and faster to set up than a generator.
What this number is, and is not
One caveat before relying on Clinton County's number: it is county-wide, and it covers about 409 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. Clinton County has about 42,019 residents.
