Benewah County, ID: Tornado Risk and Shelter Cost
Benewah County, ID: what NOAA's tornado record says
NOAA's Storm Prediction Center has no recorded tornado touching Benewah County in the 76 years of the database, 1950 through 2025. That is a real result, not a gap in the data - most of the Northeast and Pacific coast reads this way. Against the rest of the country, that is the 2nd percentile for frequency. Among 44 Idaho counties in this dataset, Benewah County ranks 43 for how often a tornado touches down.

Paying for it, if Benewah County's history says you should
A storm shelter or in-residence safe room typically runs $2,890-$13,280 nationally, around $7,645 for a common single-family installation. No state-administered rebate program specific to Idaho was confirmed for this site - FEMA's own Hazard Mitigation Assistance grants fund 75% of an approved safe room nationwide, but only some states currently run a homeowner-facing application on top of that.
The gap a shelter does not cover
A direct hit is not required for Benewah County to lose power - outbreak-wide outages across Idaho regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Benewah County covers about 777 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. And records from before the 1990s, NOAA notes, undercount weaker tornadoes in areas with less storm-spotting coverage at the time. Benewah County has about 10,529 residents.
