Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
700 PM EDT Thu Jul 23 2026

.SYNOPSIS...

Atlantic high pressure will continue to extend its axis across the
southeastern states through Friday, creating prevailing onshore
winds across our local waters. Meanwhile, a stationary frontal
boundary extending from the Mid-Atlantic states into the lower
Mississippi Valley 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 for much of 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.
