Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1102 AM EDT Wed Mar 27 2024

.SYNOPSIS...
A slow moving cold front stretching across the Florida Big Bend
region to coastal Carolina this late morning will approach our
local waters this evening. A wave of low pressure will develop
along this front tonight, with this feature strengthening as it
accelerates northeastward off the Carolina coast on Thursday.
Showers and thunderstorms will overspread our region this
afternoon, with strong to isolated severe thunderstorms possible
over our local waters late this afternoon through this evening.
Stronger activity will be capable of producing strong wind gusts,
hail, and frequent lightning strikes. Waves of downpours and
embedded thunderstorms will continue along this slow moving front
overnight through Thursday morning, followed by a surge of
northwesterly winds on Thursday afternoon following the passage of
the front. Elevated seas will continue through Thursday, with
Small Craft Advisory conditions persisting offshore. Winds may
briefly reach Small Craft Advisory levels on Thursday afternoon
before shifting to northerly while gradually diminishing on
Thursday night and Friday. High pressure will then build directly
over our waters on Friday evening before shifting southward this
weekend, allowing for prevailing south- southwesterly winds.
