A cold front moved east across the coastal waters of southeast Louisiana and coastal Mississippi during the morning of January 25th. A line of showers and thunderstorms developed along and just ahead of the front within a moist and moderately unstable airmass. As the line progressed eastward, embedded cells within this line produced severe wind gusts at multiple locations of the local marine areas.

Began near Grand Isle Station (gisl1) (29.2600, -89.9600).
