The path drawn at its surveyed width of 250 yards (0.14 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 survey team found that an EF0 tornado with maximum wind speeds of 80 mph and a maximum path width of 250 yards travelled 1.7 miles across a portion of south central DeKalb County. The tornado touched down just north of I-20 near Wesley Chapel Road and Cross Lane, snapping several small trees and pulling a few shingles off of roofs. The tornado moved north northwest causing more extensive damage between Lindsey Drive and Oak Valley Road. In this residential area, including Sherwood Avenue and Hanes Drive, multiple large trees were snapped or uprooted with several falling on homes and taking down utility/power lines. The tornado weakened as it continued north northwest with several additional small trees snapped along its path over Belvedere Square and just across Covington Highway along South Indian Creek Drive. No injuries were reported. [10/10/20: Tornado #6, County #1/1, EF-0, DeKalb, 2020:033].
