How Likely Is a Tornado in Benton County, TN?
Benton County, TN: what NOAA's tornado record says
Benton County has recorded 26 tornado touches in NOAA's 76-year database, a rate of roughly one every 2.9 years - our Elevated band. Put another way: Benton County sees more tornado activity than 62% of US counties. Tennessee has 95 counties in this dataset; Benton County ranks 21 of them by frequency.
Beyond the frequency band: violent history
1 tornado touching Benton 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 Benton County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Tennessee 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 Tennessee this pass.
What a direct hit isn't required for
16,173 people live in Benton County, and a tornado outbreak's power loss usually reaches far more of Tennessee 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 Benton County's number: it is county-wide, and it covers about 394 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. Benton County has about 16,173 residents.
