Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
403 AM EDT Tue Mar 24 2026
.SYNOPSIS...
A strong cold front will move across the area waters early this
morning. Gale warnings and small craft advisories are in effect for
the rapid northeasterly wind surge behind the front today through
Wednesday. Scattered showers and possibly a thunderstorm are
expected today through tonight mainly across the northeast Florida
waters. High pressure will then begin to build in from the north
Wednesday night resulting in winds lowering but seas will remain
elevated and rough. Another cold front will enter the southeast
states on Friday night, crossing our local waters on Saturday.
Strong high pressure will again build to the north of our area in
the wake of this front, resulting in another surge of onshore winds
throughout our local waters and possible Gale conditions during the
weekend.
