Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
307 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. Small
Craft Advisory conditions over the Georgia waters and the offshore
waters north of St. Augustine this morning will overspread the
rest of the northeast Florida waters by this afternoon as north-
northeasterly winds strengthen and seas build. 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.
