Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
427 AM EDT Fri Mar 27 2026
.SYNOPSIS...
Atlantic high pressure will sink slowly southward today as a
strong cold front enters the southeastern states this evening.
Breezy southerly winds will develop early this evening ahead of
this approaching front, with this boundary moving from north to
south across our local waters during the early to mid morning
hours on Saturday. Strong high pressure building into the Ohio
Valley in the wake of this frontal passage will wedge down the
southeastern seaboard this weekend, creating a surge of strong
northeasterly winds that will reach Gale thresholds throughout our
local waters through early Sunday morning, with seas quickly
building on Saturday afternoon.
Coastal troughing will also develop over our near shore waters on
Saturday afternoon, with this feature generating showers and
possibly a few embedded thunderstorms, mainly for the northeast
Florida waters through early Sunday afternoon. Strong high
pressure will then migrate eastward off the Mid-Atlantic coast on
Sunday afternoon, allowing for winds to shift to an easterly
direction with gradually diminishing speeds. Small Craft Advisory
conditions will prevail from Sunday through Monday morning, with
seas gradually diminishing near shore by late Monday. Strong high
pressure will then become centered near Bermuda by Tuesday, with
breezy southeasterly winds forecast through midweek.
