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

The tornado continue northeast, crossing Willie Varnum Road, causing significant tree damage, supportive of an EF-1 rating with max winds estimated near 90 mph.

Thanks to Houston County, Alabama Emergency Management for assistance with this survey.

The wider storm

A high impact severe weather event impacted the tri-state region on January 9th with supercells producing tornadoes, large hail, and damaging wind gusts, followed by a major squall line with widespread wind damage and additional tornadoes. Preceding this activity, very strong non-thunderstorm wind gusts of 40-60 mph occurred, with even a gust to 70 mph at the Albany airport. There were 14 tornadoes confirmed across the tri-state region, including 3 EF0s, 5 EF1s, 5 EF2s, and 1 EF3. This activity was driven by a deepening area of low pressure west of the region with a record strong low level jet crossing the region. The winds at 850 mb were in in the 65-80 knot range, and sufficient instability existed to support mixing some of these very strong environmental winds to the surface.

Began near Memphis (31.1350, -85.3554).
