Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1229 PM EST Mon Nov 17 2025

.SYNOPSIS...

High pressure will shift east-southeastward from the Ohio Valley
towards the Carolinas by Monday evening, pushing a weakening and dry
cold front south of our local waters. Onshore winds will develop
this afternoon while briefly strengthening, followed by high
pressure settling directly over our local waters later tonight and
Tuesday, allowing for lighter onshore winds. Weakening high pressure
will then shift offshore of the southeastern seaboard on Wednesday
and will remain in control of our weather pattern through Saturday
before another weakening cold front enters the southeastern states.
This front will likely cross our local waters on Saturday night or
Sunday, with a brief period of breezy southwest to westerly winds
expected this weekend, with a few showers possible during the
frontal passage.
