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 Dallas County and determined that it was consistent with an EF0 tornado, with maximum sustained winds near 75 mph.

This tornado was a continuation of a track from Perry County. The tornado entered Dallas County about one-half mile north of County Road 54. It lifted shortly after entering the county producing mainly tree damage.

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 Blalock (32.3538, -87.4226).
