Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
849 AM EDT Wed May 28 2025
.SYNOPSIS...
Scattered thunderstorms are likely to develop along the pinned
sea breeze this afternoon and shift eastward over the nearshore
waters and weaken as they progress offshore. Little change in the
flow pattern will yield similar weather trends on Thursday. By
Friday, west flow will strengthen to Exercise Caution levels offshore
ahead of an approaching cool front. Strong to severe thunderstorms
are possible ahead of the front as it pushes across the waters
Friday night. A drier airmass and a weak pressure pattern should
allow a sea breeze dominant weather pattern to return and fair
weather this weekend.
