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

An elderly woman was injured when her mobile home was shifted from the foundation on Kennedy Street. There was also minor damage to trees and an apartment complex car port. The tornado touched down after crossing the river near River Road and moved to the north-northwest for 0.75 miles. The maximum estimated winds were 80 mph. The time of the tornado was estimated by radar.

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 Ama (29.9603, -90.3033).
