The path drawn at its surveyed width of 25 yards (0.01 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

A National Weather Service storm survey determined that a second brief tornado touched down associated with the same supercell thunderstorm as the Haralson County tornado. The tornado touched down near railroad tracks just south of Coots Lake Road where some trees were uprooted. From this point the tornado traveled to the north-northeast. The most damage occurred in a wooded area 0.3 miles north of where the tornado touched down. At this point approximately 50 trees were snapped and about 25 trees were uprooted. The tornado dissipated in an open area just short of a residence. Damage was confined to trees.

The wider storm

A well-defined upper shortwave pushed through the Deep South in late on the 11th.

Numerous showers and thunderstorms developed ahead of the front, with several reports of large hail, including a couple of reports of up to baseball sized hail and several reports of golfball sized hail. Three weak tornadoes occurred as well, two EF-1s and an EF-0.
