Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
910 AM EST Thu Dec 4 2025
.SYNOPSIS...
High pressure situated along the southeastern seaboard this
morning will shift eastward today as low pressure organizes along
the northern Gulf coast. This developing storm system's warm
front will lift northward across our local waters on Friday,
accompanied by showers and possibly an isolated thunderstorm.
Weak low pressure will move northeastward across southeastern
Georgia on Friday 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 by Monday
afternoon and night.
