Cook County, MN: Tornado Risk and Shelter Cost
Cook County's tornado history, by the numbers
NOAA's Storm Prediction Center has recorded 4 tornado tracks touching Cook County since 1991 - about one every 18.9 years on average. That puts it in our Minimal band nationally. Against the rest of the country, that is the 13th percentile for frequency. Among 87 Minnesota counties in this dataset, Cook County ranks 87 for how often a tornado touches down.
Has Cook County ever had a violent tornado?
Nothing violent in Cook County's file: 4 tracks total, topping out at significant (EF2-3) strength on 1 of them, zero at EF4-5.
Paying for it, if Cook 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 Minnesota 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
The storm that misses Cook County outright can still take its power out - outbreak-scale outages across Minnesota are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Cook County covers about 1,453 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. Cook County has about 5,571 residents.
