Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
222 PM EDT Fri Apr 4 2025

.SYNOPSIS...

Strong high pressure centered near Bermuda will maintain gusty
southeast to southerly winds across our local waters through
Saturday evening. A southerly wind surge will likely result in
Caution conditions developing offshore on Saturday afternoon.
Meanwhile, a strong cold front entering the southeastern states on
Sunday will shift prevailing winds to southwesterly, with Caution
conditions likely expanding to the near shore waters. Showers and
thunderstorms will then overspread our local waters on Monday
afternoon and evening as the cold front approaches our region from
the northwest, with a few strong thunderstorms possible. Gusty
northwesterly winds will develop in the wake of this frontal
passage by early Tuesday morning, with winds shifting to northerly
by Tuesday afternoon as high pressure building over the Ohio and
Tennessee Valleys begins to wedge down the southeastern seaboard.
Weak low pressure developing over the Bahamas towards midweek will
likely bring Small Craft Advisory conditions to our local waters
as northeasterly winds strengthen and seas build.
