What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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 touched down in Avoyelles Parish and moved northeast through the Lake Ophelia NWR. Many trees were downed along the path. The NWS survey team concluded this tornado crossed the Red River just southwest of Acme, LA where it briefly entered Catahoula Parish. The path length in Catahoula was 1.1 miles and the total path length was 13.7 miles.

The wider storm

A potent storm system for early Fall impacted the region and a line of showers and thunderstorms moved through the ArkLaMiss region ahead of a cold front. A rare combination of instability and wind shear was in place and storms produced tornadoes, along with damaging winds.

Began near Book (31.2677, -91.8376).
