Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
722 AM EST Fri Jan 23 2026
.SYNOPSIS...
A frontal boundary will linger over the southeast Georgia waters
today as high pressure retreats into the Atlantic. Patchy dense fog
with visibility of 1 NM or less will be possible along the nearshore
waters early this morning into potentially early afternoon. Arctic
high pressure will then build northwest of the area today and push
the frontal boundary southward, crossing our local waters later
tonight into Saturday morning. Northeast winds briefly surge in the
wake of this frontal passage on Saturday with elevated seas building
in from the northeast. Meanwhile, a winter storm developing over
Texas and the lower Mississippi Valleys on Saturday and Saturday
night will shift northeast, lifting a warm front northward across
our local waters on Saturday night. Small craft advisory level seas
develop across the southeast Georgia waters Saturday afternoon and
then build into the offshore northeast Florida waters Saturday
night. Winds will shift to south and then southwest on Sunday ahead
of another cold front, which could be accompanied by a few
thunderstorms on Sunday afternoon and night. Arctic high pressure
will then build into the southeast states in the wake of this cold
frontal passage early next week, continuing Small Craft Advisory
conditions into early next week as breezy northwest winds shift to
north while strengthening further on Monday night.
