The path drawn at its surveyed width of 200 yards (0.11 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

The tornado developed as it moved eastward off of a ridge and down into the Hooper Branch Creek valley along Pond Ridge Road. Many trees were uprooted in this area. It continued eastward over a ridge where it damaged fences and destroyed a small barn. As the tornado approached and crossed Highway 68, additional trees were uprooted with some roof damage to a few structures. Before the tornado dissipated, it shifted a double wide on its foundation, broke several windows, and uprooted additional hardwood trees.

The wider storm

Thunderstorms developed ahead of an upper level system and surface cold front during the evening hours. Several of these storms produced large hail and wind damage. Funnel clouds were reported as a discrete supercell thunderstorm developed over Southeast Tennessee and moved into Southwest North Carolina. As this supercell moved into Monroe County, Tennessee, a weak tornado developed downing several trees and producing minor structural damage.

Began near Coker Creek (35.2963, -84.3049).
