Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
113 PM EDT Wed Aug 27 2025

.SYNOPSIS...

Stalled frontal boundary to the south will lift back across the
waters tonight as a high pressure ridge axis extends across southern
Florida. A weak circulation will attempt to organize along the front
and increase rain and thunderstorm chances through tonight. High
pressure builds to the northeast Thursday as the front continues to
lift back northward. The front will linger across the local waters
Friday into the weekend with a return of elevated shower and
thunderstorm chances through the upcoming holiday weekend. Another
unseasonable cool front will wedge down the coast early next week,
prompting another potential northeasterly wind surge.
