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

.SYNOPSIS...

A slow moving cold front stretching across the Florida panhandle
early this 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.
