Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
225 PM 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 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.
