What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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

An EF-1 tornado developed near the border of Joe Wheeler State Park and the Tennessee River. Almost immediately, a large swath of trees were either snapped or uprooted. Both hardwood and softwood trees were toppled, leading to a rating of high-end EF-1. Park officials estimate thousands of trees fell as a result of this tornado. The peak width was 500 yards, with evidence of multiple vortices present both to the east and west of the bay. There were multiple swaths of convergent tree damage, as well as gaps of standing trees in between these swaths. It is worth noting that several structures remained standing in the middle of these swaths and all damage to those structures was the result of falling trees.

Continuous tree damage was observed across the remainder of Joe Wheeler State Park. Sporadic damage was then noted with trees along McLean Drive, across Lover's Lane, and over to Braden Cove where an RV was toppled, several houses had minor roof damage, and a few trees were snapped. The tornado then shrank considerably and uprooted a few pine trees and then lifted just east of Tipton Road.
