Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1229 AM EST Tue Nov 11 2025

.SYNOPSIS...

Strong high pressure building into the southeastern states will keep
strong northwesterly winds and Gale Warnings in place through around
sunrise for the Georgia waters and through the late morning hours
for the northeast Florida waters. High pressure will shift eastward
towards our region this afternoon, allowing northwesterly winds and
seas to gradually diminish. High pressure will then shift southward
over the Florida peninsula on Thursday ahead of a weakening and dry
frontal boundary that will push southward and dissipate across our
local waters on Thursday night. Another high pressure center
building over the Tennessee Valley on Thursday will settle
southward, moving directly over our area by Friday night and
Saturday.
