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

Damage occurred near the intersection of Highways 25 and 76. Four frame homes, per newspaper report, and a mobile home suffered significant roof damage along Creekmore Road. Numerous trees were snapped or uprooted. Per newspaper report, numerous power lines were downed.

The path length of the tornado was 0.6 mile with a maximum path width of 50 yards. The damage was rated EF-1 in intensity, with maximum wind speeds around 100 mph.

The wider storm

This resulted in 10 tornadoes across the mid state, with one being an EF4 Tornado in Murfreesboro in Rutherford County.
