Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
835 AM EST Wed Dec 3 2025

.SYNOPSIS...

High pressure will build over the southeastern states this
afternoon in the wake of a cold front that will stall across south
Florida tonight. Low pressure will then organize along the
northern Gulf coast on Thursday night, with a warm front lifting
northward across our local waters on Friday, accompanied by an
increasing coverage of showers. Weak low pressure will then move
northeastward across southeastern Georgia on Friday evening, 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, keeping showers and a few embedded
thunderstorms over 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.
