.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A weak surface low has moved to the east with offshore flow now over
all of the coastal waters but the front will stall just to the south
of the coastal waters. Winds have already relaxed over much of the
area and will continue to remain light through the remainder of
today and this evening. As the stalled front front drifts back to
the north tonight winds will be a little more chaotic but still
light. We finally see a stronger cold front push through Sunday
night with moderate to possibly strong offshore winds developing.
SCS or SCY headlines will likely be needed for portions of the
coastal waters overnight and into Monday. High pressure quickly
builds back into the area Monday and Monday night.
