The dollar figure Flathead County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Montana 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 Montana this pass.
What a direct hit isn't required for
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.
What this number is, and is not
One caveat before relying on Flathead County's number: it is county-wide, and it covers about 5,087 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. Flathead County has about 114,527 residents.
