How Likely Is a Tornado in Oneida County, WI?
How likely is a tornado in Oneida County, WI?
Oneida County has recorded 22 tornado touches in NOAA's 76-year database, a rate of roughly one every 3.5 years - our Moderate band. Put another way: Oneida County sees more tornado activity than 55% of US counties. Wisconsin has 72 counties in this dataset; Oneida County ranks 42 of them by frequency.
Beyond the frequency band: violent history
1 tornado touching Oneida 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 Oneida County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Wisconsin 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 Wisconsin this pass.
What a direct hit isn't required for
Power loss after a tornado outbreak in Wisconsin often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What this number is, and is not
One caveat before relying on Oneida County's number: it is county-wide, and it covers about 1,114 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. Oneida County has about 38,175 residents.
