Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
225 PM EDT Wed Sep 2 2026
.SYNOPSIS...
A trough will progress westward across our local waters this
afternoon and evening, providing breezy northeasterly wind and
numerous showers and embedded thunderstorms through this evening.
Winds will shift to easterly with gradually decreasing speeds later
tonight as the trough shifts onshore, with breezy southeasterly
winds forecast on Thursday, along with scattered to numerous showers
and a few embedded thunderstorms. Weak Atlantic high pressure will
then build westward towards the southeastern seaboard on Friday,
maintaining a light southeast wind flow that will again produce
scattered to numerous showers and a few embedded thunderstorms.
Prevailing westerly winds are then expected from Saturday through at
least Monday morning as a frontal boundary sinks southward towards
our region, with this feature maintaining a stormy weather pattern,
especially during the afternoon and evening as activity pushes
eastward from coastal locations. Stronger high pressure will build
down the southeastern seaboard early next week in the wake of this
boundary, likely pushing the front over the northeast Florida
waters. Breezy onshore winds will gradually overspread our local
waters by Monday afternoon and night.
