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

Numerous large trees were felled or snapped by the tornado, including several trees landing on and near mobile homes. Another tree fell on the rear portions of a car. A barn suffered minor roof damage to a carport attachment, with debris strewn downwind.
