Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
746 AM EDT Sat Sep 26 2026

.SYNOPSIS...

Strong low pressure to the northeast will track further away to the
north through the end of the weekend as high pressure builds
southward from the eastern Great Lakes into the southeast. As low
pressure lifts away, the pressure gradient will ease over the region
with gradually diminishing winds and seas through this evening,
ending small craft conditions nearshore late this morning and
offshore this evening. High pressure will shift over the region
Sunday and Monday with prevailing west to southwest winds, turning
southeasterly in the afternoon nearshore from the Atlantic seabreeze
circulation. High pressure will shift east of the waters midweek
with southerly winds, turning easterly in the afternoon over the
nearshore waters from seabreeze circulation. Increasing moisture
will bring a return of scattered showers and isolated thunderstorms
over the waters by midweek.
