Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1247 AM EDT Fri Jul 24 2026

.SYNOPSIS...

Southerly winds will continue this morning as high pressure ridge
axis across the Atlantic northeast of Bermuda stretches southwest
across the area waters through Tonight with east southeasterly winds
this afternoon from Seabreeze circulation. A stationary frontal
boundary extending from the Carolina coast westward across the deep
south will begin to drift southward towards the Georgia waters this
weekend, 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 midweek.
