Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
226 PM EDT Sat Oct 3 2026
.SYNOPSIS...
Southeasterly wind continues over the weekend with waves of showers
and thunderstorms moving from south to north. Outside of
thunderstorm activity, winds and seas are expected to remain below
Caution levels through at least Monday afternoon.
Deteriorating conditions are expected Tuesday as cold front enters
and stalls over the area waters. Following the front, a strong high
pressure building will wedge down the southeastern seaboard,
initiating a prolonged surge of strong northeasterly winds and high
seas across our local waters. Small Craft Advisory conditions are
likely by Tuesday, with the potential for wind gusts near Gale force
through Thursday. Northeasterly winds are expected to gradually
decrease through Friday, allowing seas to lower thereafter.
