Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
212 AM EDT Sun Aug 3 2025

.SYNOPSIS...

A stalled front will lay along the Florida and Georgia state line
and extend into the coastal waters today and Monday. Numerous
afternoon thunderstorms are expected to develop along the boundary
and push into the coastal waters. The front will begin to dissipate
by Tuesday and possible lift northward as high pressure develops to
the northeast. A weak trough well offshore may foster a weak low
pressure system along it to the northeast during the latter half of
next week resulting in a prevailing onshore flow and also elevate
seas.
