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

Although the center line of this tornado did not move into Coal County from Atoka County until one-third of a mile west of US-75, the north edge of the tornado had expanded into Coal County producing tree damage 7 miles farther west, to the west of NS-376 Road. As the tornado approached US-75, the tornado produced slight roof damage to a house on Mockingbird Lane just north of the county line. The tornado damaged a radio station building at US-75 as the center line crossed into Coal County and began moving northeast. The tornado continued moving northeast through a rural area of southeastern Coal County before turning back to the east and moving into Atoka County near EW-177 Road.
