How Likely Is a Tornado in Otter Tail County, MN?
How likely is a tornado in Otter Tail County, MN?
Otter Tail County has recorded 89 tornado touches in NOAA's 76-year database, a rate of roughly one every 0.9 years - our High band. Put another way: Otter Tail County sees more tornado activity than 97% of US counties. Minnesota has 87 counties in this dataset; Otter Tail County ranks 1 of them by frequency.
Beyond the frequency band: violent history
3 tornados touching Otter Tail 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 Otter Tail County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Minnesota 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 Minnesota this pass.
What a direct hit isn't required for
60,884 people live in Otter Tail County, and a tornado outbreak's power loss usually reaches far more of Minnesota 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 Otter Tail County's number: it is county-wide, and it covers about 1,972 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. Otter Tail County has about 60,884 residents.
