Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
205 PM EDT Thu Sep 24 2026
.SYNOPSIS...
Low pressure will strengthen well to the northeast of the region
through the end of the week, tracking further to the north of the
area through the weekend. High pressure will build down the eastern
US coastal states Today pushing a backdoor cold front south of the
waters. The gradient between the high, and the front trailing from
the low to the northeast, will result in enhanced northeasterly
winds and waves lasting through at least Friday. A prolonged period
of Small Craft conditions will continue through at least Saturday.
There is also potential for occasional gusts to near Gale force
today into this evening. These conditions ease this weekend as high
pressure weakens and the aforementioned low pulls further away from
the area.
