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 first touched down just south of Highway 18 and tracked east northeast to County Road 421, then into Alabama. Hundreds of trees were snapped and uprooted. A roof to a house was damaged, two outbuildings were heavily damaged and a deer stand was destroyed. Maximum winds were around 110 mph. Total path length across MS/AL was 15.6 miles.
