Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1043 AM EDT Sun Jun 30 2024

.SYNOPSIS...

Atlantic high pressure stretching its axis westward across the
northeast Florida waters this afternoon will sink southward
tonight as a frontal boundary approaches our local waters from the
north. Offshore winds will prevail ahead of this approaching
frontal boundary, except near shore, where the Atlantic sea breeze
will push inland during this afternoon. Widely scattered showers
and thunderstorms will be possible this afternoon and evening,
mainly over the near shore waters. This frontal boundary will
stall the Georgia waters on Tuesday, with increasing chances for
mainly afternoon and nighttime showers and thunderstorms across
our local waters. Prevailing winds will shift to east and
southeasterly beginning on Tuesday as high pressure builds down
the southeastern seaboard. High pressure will then weaken as it
shifts southward towards our local waters later this week.
