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

.SYNOPSIS...

Atlantic high pressure 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
this afternoon. Widely scattered showers and thunderstorms will
be possible into the evening hours today, mainly over the near
shore waters. The frontal boundary will stall over 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.
