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

Ooltewah-to-Cleveland Tornado. An EF1 tornado continued its path to the northeast from Hamilton county almost parallel to I-75 into western Bradley County. The tornado path showed a slight right bend at near 35.140N/84.993W, then continued to the northeast into the north side of Cleveland. The 90 mph wind downed numerous trees and slightly to moderately damaged several roofs throughout its path. A 56 year old man was killed due to flying debris and trees landing on the vehicle he was driving.
