Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
804 AM EDT Sat Mar 28 2026
.SYNOPSIS...
A strong cold front will cross the Georgia waters early this morning
and the northeast Florida waters during the mid-morning hours. West-
southwesterly winds ahead of this front will briefly shift to
northwesterly as the front passes early this morning. Meanwhile,
strong high pressure building over the Upper Midwest in the wake of
this cold front will shift southeastward towards the Ohio Valley on
Saturday afternoon, with this feature wedging down the southeastern
seaboard. This will create a surge of strong northeasterly winds
from north to south during the mid to late morning hours, bringing
Gale conditions and building, very rough seas to our local waters by
early this afternoon. Coastal troughing will also take shape over
the near shore waters adjacent to northeast Florida this afternoon,
generating scattered showers that will persist into Sunday.
Strong high pressure will continue its southeastward progress
tonight, with this feature shifting off the Carolina coast near the
Outer Banks by early Sunday afternoon. Winds will shift to easterly
towards sunrise on Sunday, with Small Craft Advisory conditions
continuing through Sunday night and Monday across our local
waters.Coastal troughing will dissipate by Tuesday as Atlantic high
pressure extends its axis westward across the southeastern states,
with breezy southeasterly winds expected to continue through late
next week, maintaining elevated seas across the offshore waters.
