Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1229 AM EST Mon Dec 15 2025
.SYNOPSIS...
Breezy northwesterly winds will shift more towards the north to
northeast throughout the morning hours behind a cold front that has
moved through. Frequent gusts to gale force are expected over all
waters with a Gale Warning in effect. Rough waves will be expected
as well, as high as 10 feet offshore and across the NE FL coastal
waters, as well as breakers up to 7-8 feet in the surf zone south of
Duval County with a High Surf Advisory in effect through the
afternoon. Coastal troughing will develop overnight which will
increase cloud cover as well as isolated to scattered shower
chances, especially further offshore. Weakening high pressure will
then shift southward Tuesday, allowing winds and seas to subside.
High pressure then shifts offshore on Wednesday afternoon in advance
of a weakening frontal boundary that will likely cross the Georgia
waters on Friday morning and may then stall over the northeast
Florida waters by Friday night.
