The path drawn at its surveyed width of 30 yards (0.02 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

NWS storm survey found the path of an EFO tornado that apparently developed over Lake Norman before moving onshore at the Lake Campus of Davidson College. Picnic tables were blown into the water and a large hardwood tree was snapped. Numerous spots along the shore between the Lake Campus and I-77 saw snapped tree trunks or large branches. One large poplar tree was uprooted and damaged other large trees as it fell. One fence was damaged along with a wellhead. The tornado crossed I-77 at about 7:30 am, and more sporadic damage subsequently occurred across the south sides of Mount Mourne and Mooresville. Numerous large, healthy tree branches were downed between Langtree Rd and Blackwelder Farm Dr. In the vicinity of Mooresville Middle School, a fence collapsed and a tree was uprooted. Uprooted trees and branch damaged occurred in a few spots between Linwood Rd and Teeter Rd. The tornado ended along Teeter Rd just short of the Rowan County line.
