What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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-2 tornado touched down in Tellico Plains, leaving a path of destruction 14 miles long through downtown and crossed Hwy 360 to Ballplay Road, and into the Citico Wilderness area. Property damage to residential and commercial buildings was extensive (30 buildings), but, although there were 3 injuries, miraculously, there were no fatalities. One of the TDS buildings and the police department annex were destroyed. The cabins, main lodge and pavilion at the KOA Campground were leveled. Downed, broken, and uprooted trees cover hillsides and roadsides in the tornado's path.

The wider storm

A deepening low pressure system moved northeast from the Mid Mississippi Valley through the Great Lakes initially driving a warm front northward through the Southern Appalachian region during the afternoon. The associated cold front swept across the area late Friday night. A one hundred knot upper level jet positioned over a 50 knot low level jet resulted in a strongly sheared environment. The intense shear and moderate instability produced an atmosphere conducive to long-lived, discrete, supercell thunderstorms. A total of 9 tornadoes ranging in intensity from EF-0 to EF-3 produced widespread damage and nearly 50 injuries to East Tennessee residents in the path of the storms.

Began near Tellico Plains (35.3681, -84.3061).
