Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
900 AM EDT Sun Sep 15 2024

.SYNOPSIS...

Low pressure will continue to organize over the Gulf Stream waters
adjacent to the Carolina coastline, with this feature
potentially acquiring tropical characteristics as it pushes
northward towards the Carolina coast on Monday night or early
Tuesday morning. Waves of showers and a few embedded thunderstorms
will develop across our local waters through Monday night. Winds
will shift to northwesterly on Monday night while diminishing,
with seas then gradually diminishing through midweek. Otherwise, a
frontal boundary positioned across the Florida peninsula will
lift northward over the northeast Florida waters on Wednesday,
keeping chances for mainly afternoon and evening thunderstorms in
place. This front will then shift south of our local waters late
this week.
