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

National Weather Service meteorologists surveyed damage in northwest Winston County near Forkville and determined that the damage was consistent with an EF-1 tornado, with maximum winds estimated near 105 mph.

The tornado touched down about 5 miles east northeast of Haleyville. At initial touch down along Chicken Foot Road, there were a few trees that were blown down and minor damage to a garage roof. The tornado continued northeastward where it snapped several power poles, one home suffered roof damage, and some garage doors were blown in. A metal pole and rafter barn was destroyed and the debris was scattered across a field. Toward the end of the path, several tree trunks were snapped off.
