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

Surface high pressure will generally remain centered over the
Southeast US through much of the forecast period. This will allow
for a continuation of onshore flow. Overall, the flow should remain
light with favorable winds and seas through the weekend and into the
start of next week. Progressing into late next week, a cold front
moving through will bring the potential for hazardous winds and
seas.
