Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
126 AM EDT Wed Jul 30 2025

.SYNOPSIS...

A trough of low pressure near GA waters will lift northward
through Wednesday as high pressure ridging builds back into the
region. This regime will then change little through at least
Friday, which will result in a light offshore wind at night and a
developing sea breeze during the daytime each day. A frontal
boundary will approach area waters by Friday Night, and stall just
north of or over GA waters for the weekend, resulting in an active
pattern and higher chances for showers and thunderstorms.
