Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
833 PM EDT Mon Apr 27 2026
.SYNOPSIS...
Breezy northeasterly winds and elevated seas will persist over our
local waters this evening continuing advisory conditions over the
offshore waters of northeast Florida and southeast Georgia with
exercise caution conditions over the nearshore waters. High pressure
will weaken as it moves southeastward Tuesday, becoming positioned
off the southeastern seaboard, allowing for onshore winds and seas
to gradually subside through Tuesday night.
A cold front will approach from the northwest Wednesday, possibly
bringing a few showers and thunderstorms to the Georgia waters
during the afternoon and evening hours. This front will then
slowly move across the rest of our local waters on Thursday and
Thursday evening, accompanied by showers and thunderstorms. This
front will briefly shift south of our region on Friday before a
wave of low pressure develops over the Gulf this weekend, likely
spreading additional showers and thunderstorms across our local
waters during the upcoming weekend.
