What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A tornado touched down in Iron Mountain causing tree damage and minor roof damage before moving northeast. From there, the tornado moved northeast causing similar damage on Highway N and severely damaging a home's roof on Lake Avalon Road. The tornado dissipated shortly after.
