Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1229 AM EST Fri Dec 5 2025
.SYNOPSIS...
Weak low pressure along the northern Gulf coast will lift a warm
front northeastward across our local waters today, accompanied by
showers and possibly an isolated thunderstorm. Weak low pressure
will move northeastward across southeastern Georgia this afternoon,
with this storm system's cold front then crossing our local waters
on Friday night and Saturday morning. A wave of low pressure will
then develop along this front just south of the northeast Florida
waters on Saturday night, with widespread rainfall and a few
embedded thunderstorms likely across our local waters through
Sunday. Low pressure will then strengthen as it moves offshore on
Sunday night and Monday, resulting in strengthening north
northwesterly winds as rainfall ends, with Small Craft Advisory
conditions possible from Monday through early Tuesday.
