How Likely Is a Tornado in Iron County, MI?
How likely is a tornado in Iron County, MI?
Iron County has recorded 8 tornado touches in NOAA's 76-year database, a rate of roughly one every 9.5 years - our Low band. Put another way: Iron County sees more tornado activity than 23% of US counties. Within Michigan alone, Iron County ranks 58 of 83 counties for tornado frequency.
Beyond the frequency band: violent history
7 weak and 1 significant tornadoes make up Iron County's 8-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Iron County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Michigan 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 Michigan this pass.
What a direct hit isn't required for
Power loss after a tornado outbreak in Michigan 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 Iron County's number: it is county-wide, and it covers about 1,166 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. Iron County has about 11,709 residents.
