The path drawn at its surveyed width of 50 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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

A weak tornado crossed Bayou Dularge and Louisiana Highway 315 about 8.9 miles southwest of the community of Theriot. Minor roof damage occurred to a few homes and sheet metal roof panels were pulled from roofs of storage buildings. Four medium sized boats were overturned in Bayou Dularge. Maximum winds were estimated at 75 mph. Damage path was approximately 150 yards long and 50 yards wide.

The wider storm

Low pressure moved from south Texas to southwest Louisiana during the day and night of the 25th. A warm front associated with the low pressure provided the focus for isolated thunderstorms that produced two tornadoes over southeast Louisiana. In addition, persistent strong southeast and winds generated by a strong pressure gradient produced several reports of minor wind damage primarily to trees. Strong onshore wind caused tides to be 1 to 3 feet above normal, but locally higher. Minor to moderate coastal flooding occurred in low lying terrain in coastal areas and near tidal lakes. Very heavy rain also occurred with this system with several locations receiving as much as ten inches of rain over a 48 hour period. However, due to drought conditions prior to this storm, flooding was much less than usual.

Began near Dulac (29.3405, -90.8382).
