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 Marion County and determined that it was consistent with an EF1 tornado, with maximum sustained winds near 90 mph. The tornado touched down just southeast of the intersection of County Road 13 and Grant Road. It rapidly intensified as it tracked northward and crossed County Road 13, where it uprooted dozens of pine trees and a few hardwoods. The tin was partially torn off a small barn and was deposited to the west of the path. Just as quickly as the tornado intensified, it dissipated just north of County Road 13 before reaching County Road 56.

The wider storm

A very potent storm system moved out of the Southern Plains States and into the Central Gulf Coast Region Saturday and into Sunday morning. This system produced widespread severe weather from Texas to Alabama, including numerous tornadoes. A line of severe storms moved into West Alabama shortly before midnight Saturday night and progressed eastward across all of Central Alabama. The line of storms produced pockets of damaging straight line winds, localized flooding, and several tornadoes.

Began near Shottsville (34.2415, -88.1425).
