Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
714 PM EST Mon Dec 15 2025
.SYNOPSIS...
Arctic high pressure centered north of the area over the Carolinas
will shift slowly south and east through Thursday. Meanwhile,
coastal troughing will take shape over the northeast Florida
waters through Tuesday. Seas will remain at Small Craft Advisory
levels for the offshore waters through Tuesday morning. Winds will
shift to south and then southwest on Thursday and Thursday night
ahead of a weakening frontal boundary that will approach our local
waters. This frontal boundary will cross our area on Friday,
shifting winds to northwest during the afternoon hours. High
pressure building north of our region on Friday afternoon and
evening will wedge down the southeastern seaboard, resulting in
winds shifting to northeast by Friday night and then east on
Saturday afternoon.
