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

A tornado rated EF1 started five miles northwest of New Tazewell and ended five miles south of Tazewell. The length was approximately 12 miles long and 150 yards wide. The greatest damage occurred across New Tazewell where several trailers were blown off their foundations. Also, trees were blown down county-wide.

The wider storm

A squall line moved through the mid south on its way into Southwest Virginia and Eastern Tennessee. A large bow developed on the line late in the evening as it approached the Cumberland Plateau. Damage was predominantly created by straight line winds. However, an EF1 Tornado also developed on the Cumberland Plateau in Claiborne county.

Began near New Tazewell (36.4811, -83.6635).
