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

This tornado started near Levee Road where it snapped a couple of trees. The tornado crossed Highway 1 and continued northeast crossing Round Lake Road, where it snapped and uprooted several trees near a home. The tornado moved northeast across some farmland snapping a few more trees. The tornado crossed Sandy Ridge Road where it caused roof damage to several homes, along with snapping and uprooting several trees. The tornado ended just northeast of Odell Road, where it downed three power poles and knocked over a pivot. The estimate peak wind was 100 mph.

The wider storm

A warm, moist airmass was in place across the region ahead of a potent January weather system. Ample wind energy also was present, which not only helped bring damaging winds with severe storms but also allowed for strong gradient winds to occur ahead of an eastward advancing squall line. Severe weather occurred in the early morning hours of January 11th and continued across the ArkLaMiss region before noon, resulting in widespread wind damage as well as some tornadoes.

Began near Round Lake (34.0377, -90.8624).
