The path drawn at its surveyed width of 120 yards (0.07 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 started approximately near Fires Creek Road and Barlow Fields Drive. This was a non-continuous track more than likely due to the terrain. There was extensive softwood tree damage noted with most trees uprooted. Many trees were snapped in the upper third of their trunks as well. Trees also fell on homes and vehicles along the track. The rear flank downdraft winds were impressive particularly along Lance Cove Road and Sweetwater Bend, just south of the Hiawassee River. The tornado weakened and ended near Poplar Cove just south of the Hiawassee River.

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 Fires Creek (35.0759, -83.8679).
