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 briefly touched down in the Albritton Road and Sparks Drive area near Warrior. Several large hardwood trees were uprooted, and several pines were snapped. Some of the trees fell onto and caused damage to houses. Several other homes in the area lost roof shingles.

The wider storm

An upper level disturbance and a nearby stationary front combined to produce numerous severe thunderstorms across Central Alabama, that included damaging winds, large hail, and several tornadoes.
