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

A tornado developed along Bethel Road about two miles south of Priceville. The tornado tracked southeast up a ridge into a residential area along Spring Valley Road and Spring Valley Trail. Wind speeds in the tornado ranged from 60 to 80 mph snapping numerous large tree limbs. At least one tall hardwood tree was partially uprooted while another was fully uprooted although it had a rotted base. A large portion of a tree was toppled onto a home along River Valley Trail causing damage to siding, gutters and the rooftop. The tornado then lifted upon reaching Shoal Creek Road.

The wider storm

A quasi-linear convective system (QLCS) dropped southward into the Tennessee Valley during the afternoon and evening hours. The airmass was very unstable, and despite low to moderate low to mid level wind shear, multiple swaths of damaging winds occurred. Within these pockets of winds, a few weak and mostly short-lived tornadoes developed. The most concentrated wind and tornado damage occurred in portions of Lauderdale, Colbert, and Lawrence Counties including the Shoals region of Florence, Sheffield, Muscle Shoals, Town Creek and Courtland. Other short-lived tornadoes occurred in Madison, Morgan and Cullman Counties. Unfortunately, one person was killed by a falling tree near West Point in Cullman County.

Began near Brooksville (34.4992, -86.8958).
