Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
225 AM EDT Sat Jul 25 2026
.SYNOPSIS...
A stationary frontal boundary extending from the Carolina coast
westward across the deep south will begin to drift south towards the
Georgia waters today through Sunday, pushing the axis of Atlantic
high pressure southward. This change in the weather pattern will
create a prevailing offshore wind flow this weekend and early next
week, with scattered to numerous afternoon and evening thunderstorms
expected across our local waters each day. A few stronger storms
will be possible during the late afternoon hours, with briefly
strong wind gusts, frequent lightning strikes, and torrential
downpours possible. Another front will approach the waters next week
with offshore southwest winds increasing to near advisory levels by
midweek.
