Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm
122 PM EST Thu Dec 7 2023

SYNOPSIS

High pressure will shift over the waters this afternoon and evening and progress eastward beyond the Gulf Stream this weekend as a cold front approaches from the northwest. The cold front will pass across the coastal waters Sunday night into Monday and elevate winds and seas to Small Craft Advisory levels, particularly offshore. Numerous showers and scattered thunderstorms will be associated with this frontal passage. Behind the front, an initial area of high pressure will build from west and then to the north through Tuesday resulting in breezy to windy onshore flow through the latter half of next week.
