Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
225 AM EDT Sat Aug 1 2026
.SYNOPSIS...
A frontal boundary will remain nearly stationary over the Georgia
waters today, while high pressure remains situated over the
southeastern Gulf. This weather pattern will create a prevailing
offshore wind flow, with the afternoon sea breeze shifting winds to
southerly in the afternoon and then back to southwesterly overnight.
Coverage of mainly afternoon and evening thunderstorms will increase
this weekend and early next week as the frontal boundary over the
Georgia waters lifts northward as a warm front ahead of another cold
front that will be entering the southeastern states. Southwesterly
winds will strengthen ahead of this front beginning Sunday morning,
with Caution level wind speeds likely and periods of Small Craft
Advisory conditions possible through early Monday. Strong storms
will be possible each afternoon and evening through Tuesday.
