Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1242 PM EST Sat Nov 15 2025

.SYNOPSIS...

High pressure will remain over the area waters today with light
northwest winds offshore becoming southerly near shore due to a weak
seabreeze developing this afternoon. The high will shift south  of
the area waters this evening with offshore west to southwesterly
winds increasing to exercise caution levels offshore ahead of an
approaching cold front that will weaken as it approaches before
stalling near or just south of the Northeast Florida waters early
next week. Light winds and fair maritime conditions continue through
Thursday under the influence of high pressure. A backdoor cold front
will bring onshore flow Thursday with a coastal trough developing by
Friday as winds begin to shift southerly ahead of another front
arriving this weekend.
