This Hazardous Weather Outlook is for portions of Gulf of Mexico.

.DAY ONE...Today and Tonight
Widespread showers with a few embedded thunderstorms will continue
to progress to the east and will come to an end by this afternoon.

Patchy marine fog has developed across the coastal waters south of
Vermilion bay. This fog will likely continue in varying densities
through the day before expanding and becoming more dense
overnight.

.DAYS TWO THROUGH SEVEN...Monday through Saturday
The cold front that moved through this morning will lift back to
the north as a warm front providing a focus for another round of
widespread showers and thunderstorms. These storms will also have
the potential to produce periods of visibility reducing heavy
rain. This rain will continue into Tuesday night before another
cold front sweeps through the area bringing the precipitation to
an end.

Marine fog will likely persist in varying densities across much of
the coastal waters Monday through early Wednesday.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not anticipated.
