Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
110 AM EDT Fri Sep 25 2026

.SYNOPSIS...

Low pressure strengthening to the northeast today will track further
to the north through the end of the weekend as high pressure builds
southward from the eastern Great Lakes into the southeast states.
The gradient between high pressure and a front to the south trailing
the low to the northeast will keep elevated winds and seas over the
area waters through tonight before diminishing Saturday. Small
Craft conditions will continue through Saturday afternoon. These
conditions ease late Saturday into Sunday as high pressure
weakens and the low pressure area lifts further away from the
area.
