Hazardous marine condition(s):
Small Craft Advisory
GMZ500-GMZ501-022300-
437 AM CST Tue Dec 2 2025
.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A broad area of low pressure just south of the coast will continue
to lift to the east-northeast into the Florida panhandle and then
southern Georgia by late this morning. We are already seeing strong
offshore winds on the back side of the surface low with winds gusts
from 25 to 30 kts west of the mouth of the river. Winds will respond
over the rest of the coastal waters as the surface low continues to
move through and lifts out. The strong offshore winds will remain in
place through midday slowly weakening throughout the afternoon as
high pressure builds over the Lower Mississippi Valley. A small
craft advisory is already in effect for all of the coastal waters
and will remain so through midday. Winds should relax enough for it
today drop off everywhere by mid/late afternoon. High pressure will
quickly slide east across the southern US with light onshore flow
returning Wednesday morning. The next system will quickly begin to
take shape with broad low pressure over the western Gulf by Thursday
and moving through the coastal waters Thursday night and early
Friday.
