.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

A broad area of high pressure will remain over the eastern Gulf
through Tuesday. This will allow for a persistent onshore flow of 10
to 15 knots. A cold front will move through the waters Tuesday night
and Wednesday. This front will shift winds to the northwest at 10 to
15 knots by Wednesday night. A few thunderstorms could accompany the
front as it moves through on Wednesday, and this could lead to some
locally higher winds and seas in close vicinity to the storms.
