Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
951 AM EDT Sat Oct 4 2025

.SYNOPSIS...

The current pattern with high pressure centered to the northeast,
and a trough over the coastal waters will continue through early
next week. This will keep the elevated and gusty winds, along with
bands of showers in the forecast. A few thunderstorms will be
possible, mainly during the afternoons. The pattern changes briefly
mid week, as the high moves away, and a cold front moves through.
However, high pressure is expected to build to the north, with
troughing over the waters later next week, bringing a return to
the elevated conditions.
