NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. Other tornadoes recorded nearby that day are shown faint.

Not rated. NOAA lists no rating for this tornado. Ratings come from surveying damage, and the National Weather Service now records “EFU” (unknown) when a tornado hit nothing a survey team could rate.

What the National Weather Service wrote

Several reports and videos were taken of a tornado over marsh east of Galliano. Lack of access and no discernible damage prevented the NWS from assigning an EF scale rating.

The wider storm

An upper level disturbance moving across the region combined with a weak surface boundary to produce isolated severe thunderstorms and a couple of tornadoes along the southeast Louisiana coast.

Began near Galliano (29.4700, -90.2335).
