Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
133 AM EDT Fri Jul 4 2025

.SYNOPSIS...

A front will stall and linger over the local coastal waters today
through the weekend. An area of weak low pressure will develop along
the frontal boundary late tonight or Saturday, and the low is
expected to meander over the coastal waters through Sunday. Elevated
winds and seas could reach Small Craft Advisory conditions mainly
across Georgia waters this weekend. The low is expected to lift
northward away from the local waters late Sunday or Monday. The
National Hurricane Center is monitoring this system to see if the
low will become a tropical or subtropical depression. As the low
departs Monday into Tuesday, a weak trough will linger across
Georgia as high pressure builds northward across the Florida
peninsula.
