How Likely Is a Tornado in Sheridan County, ND?
How likely is a tornado in Sheridan County, ND?

Put another way: Sheridan County sees more tornado activity than 58% of US counties. North Dakota has 53 counties in this dataset; Sheridan County ranks 36 of them by frequency.
Beyond the frequency band: violent history

The dollar figure Sheridan County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. North Dakota 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 North Dakota this pass.
What a direct hit isn't required for
A direct hit is not required for Sheridan County to lose power - outbreak-wide outages across North Dakota regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
What this number is, and is not
One caveat before relying on Sheridan County's number: it is county-wide, and it covers about 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. Sheridan County has about 1,268 residents.
