The path drawn at its surveyed width of 100 yards (0.06 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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 Perry County and determined that it was consistent with an EF0 tornado, with maximum sustained winds near 70 mph.

The tornado touched down in rural northwest Perry County near Willie Martin Road. This location is about 5 miles northwest of Heiberger. The tornado tracked due east and crossed Burlia Curb Road, and Jack Green Road. The tornado lifted just east of the intersection of Alvin Carter Road and Ironville Road. The tornado damage was limited to trees in this rural area. Numerous trees were snapped off and uprooted and a few trees blocked roadways.

The wider storm

A widespread severe weather event occurred across central Alabama aduring the afternoon and evening hours on Thursday, March 14th. The event began in the northwest counties and spread eastward all the way to the Georgia state line. A strong low level jet of 40-50 knots, combined with moderate instability (1000-1500 J/kg) and 0-6km bulk shear of 55-50 knots, produced an atmosphere favorable for severe thunderstorms and supercells.

Began near Morgan Spgs (32.7638, -87.3668).
