Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1245 AM EST Wed Dec 10 2025
.SYNOPSIS...
West to northwest winds will strengthen late today and tonight as
a dry cold front moves across the area. Small Craft Advisory
conditions are expected to develop over the area waters tonight
and continue until Thursday morning. A high pressure center will
build into the area Thursday into Friday and then shift offshore
by early Saturday ahead of the next frontal boundary. This front
will likely remain dry as it crosses our local waters on Sunday
night. Strong high pressure building to the north of our region in
the wake of this frontal passage will result in strengthening
northerly winds on Sunday night that will shift to northeast on
Monday. Small Craft Advisory conditions are likely throughout our
local waters from Sunday night through Monday night.
