Paying for it, if Chouteau 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 Montana 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
Power loss after a tornado outbreak in Montana often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Chouteau County covers about 3,973 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. Chouteau County has about 5,880 residents.
