Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
528 AM EDT Tue May 5 2026
.SYNOPSIS...
Atlantic high pressure centered near Bermuda will continue to
extend its axis across the northeast Florida waters through
Wednesday night. Onshore winds will become breezy across the near
shore waters this afternoon and evening, and speeds will likely
reach Caution levels on Wednesday afternoon and evening.
Otherwise, a cold front entering the southeastern states on
Wednesday night will shift prevailing winds to southwesterly
across our local waters, with this front then slowing its forward
progress as it moves across the Georgia waters on Thursday night,
followed by this front stalling over the northeast Florida waters
on Friday and Saturday. Scattered showers and thunderstorms are
expected to develop along and just ahead of the frontal boundary
across the Georgia waters on Thursday evening, with a few strong
storms possible through around midnight. Scattered to numerous
showers and thunderstorms are then expected to develop throughout
our local waters on Friday and Friday evening. Scattered showers
and thunderstorms will be possible during the weekend as the front
slowly lifts northward ahead of the next possible frontal
passage, which is forecast to occur by Monday night or next
Tuesday.
