Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1034 AM EST Sun Jan 19 2025

.SYNOPSIS...

Showers and embedded thunderstorms are slowly exiting area waters
late this morning, with this trend expected to continue through
this afternoon. Southwest winds will shift to west - northwest in
the afternoon and evening as the cold front crosses our area.

High pressure will then build over the Tennessee and Ohio Valleys
in the wake of this cold front on Monday, with this feature
wedging down the southeastern seaboard by Monday evening as a weak
wave of low pressure develops over the western Gulf of Mexico.
Northeast winds will gradually strengthen on Monday night and will
then shift to northerly on Tuesday night as low pressure organizes
off the northeast Florida coast, with Small Craft Advisory
conditions likely throughout our local waters on Tuesday night and
Wednesday, along with building seas and potential Gale conditions.
