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

The tornado toppled farm equipment, collapsed outbuildings, damaged roofs of homes, and broke large branches out of trees. Straight line winds estimated to be up to 80 MPH produced additional damage 1 to 1.5 miles beyond the tornado path. (Tornado #5 of 7).
