Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1239 AM EST Tue Jan 13 2026
Elevated northerly winds across the local waters will gradually
weaken through today as a coastal trough breaks down and shifts
farther offshore as high pressure builds across the the Gulf coast
states. The high will extend across the local waters tonight into
Wednesday as a broad surface low tracks northward well east of the
local Atlantic coast. Westerly winds increase Wednesday night as a
strong cold front moves across the region. Small craft advisory
conditions return Thursday trailing the frontal passage and continue
into Thursday night. Winds and seas subside Friday as high pressure
builds directly over the local waters. The high will shift southeast
Saturday as a weaker, dry cold front moves across the waters with a
surge in northwest to north winds behind the frontal passage late
Saturday into Sunday.
