Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
903 AM EDT Sun Apr 28 2024

.SYNOPSIS...

High pressure building southward towards the Carolina coastline
this morning will gradually weaken as it becomes situated off the
southeastern seaboard early this week. Breezy easterly winds and
elevated seas will diminish tonight, with prevailing winds
becoming southeasterly on Monday and then southerly on Tuesday. A
weakening frontal boundary entering the southeastern states on
Tuesday could develop isolated showers and thunderstorms during
the afternoon and evening hours. Atlantic high pressure will then
build westward from Bermuda later this week, resulting in
prevailing southeasterly winds. Another frontal boundary will
enter the southeastern states next weekend, possibly resulting in
increasing chances of showers and thunderstorms throughout our
local waters.
