The path drawn at its surveyed width of 600 yards (0.34 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 worst damage occurred in western portions of Franklin county. In these locations mobile homes were destroyed, multiple power poles and trees were snapped, and homes sustained significant roof damage. A 79 year old man was killed near Estill Springs, along UT Farm road, when the mobile home he occupied was picked up and thrown 70 yards.

The wider storm

A powerful cold front and upper level system combined with a marginally unstable, moist and highly sheared environment to produce severe thunderstorms and a tornado. A quasi-linear convective system (QLCS) developed during the morning hours across the mid South and raced eastward at 50 to 60 mph. The storms arrived in southern middle Tennessee around midday, with one storm intensifying into a tornadic supercell. A strong tornado of EF-2 strength tracked from just east of Lynchburg (Moore County) to just northeast of Estill Springs (Franklin County), killing a 79 year old male (near Estill Springs) in his mobile home and injuring four others.

Began near Awalt (35.2794, -86.2762).
