Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
432 AM EDT Thu Mar 26 2026
.SYNOPSIS...
Areas to widespread dense fog expected for nearshore waters
mainly north of St Augustine this morning. There is a chance of
fog over the nearshore waters again early Friday morning. A
trough of low pressure over the offshore waters will dissipate
today but will bring a chance of showers and possibly a
thunderstorm into the early afternoon. Otherwise, high pressure
will then begin to build into the area today resulting in winds
lowering but seas will remain elevated and rough at times. Another
cold front will enter the southeast states on Friday night,
crossing our local waters by early Saturday morning. 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.
High pressure ridge drop south over the area waters between
Monday and Tuesday.
