Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
722 PM EDT Mon Sep 1 2025

.SYNOPSIS...

Low pressure centered along the east central Florida coast will
shift slowly southward in tandem with a frontal boundary tonight as
strong high pressure over New England continues to wedge down the
southeastern seaboard. Gusty northeasterly winds and elevated seas
will continue through early Tuesday, with Small Craft Advisories in
place throughout our local waters into tonight. Bands of showers and
embedded thunderstorms will continue to impact our local waters
through midweek, as coastal troughing remains situated over our near
shore waters. Northeasterly winds will gradually weaken on Tuesday
and Wednesday, allowing for seas to slowly subside. Coverage of
showers and thunderstorms will then decrease later this week ahead
of a series of approaching cold fronts.
