Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
159 PM EST Wed Nov 4 2026

.SYNOPSIS...

Elevated seas will continue across the offshore waters adjacent to
northeast Florida through early this evening. Meanwhile, a cold
front entering the southeastern states tonight will slow its forward
speed, with prevailing winds shifting to southerly on Thursday and
then southwesterly on Friday and Friday night. Scattered showers and
isolated thunderstorms may impact the waters on Friday afternoon and
evening ahead of this approaching front, which will cross our local
waters before sunrise on Saturday. Winds will shift to northwesterly
with increasing speeds after midnight on Friday night, followed by
winds shifting to northerly and then northeasterly in the wake of
this frontal passage on Saturday afternoon and evening. High
pressure will gradually build into the southeastern states on
Sunday and Monday, creating breezy northeasterly winds and
gradually building seas across our local waters.
