Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
225 PM EDT Fri Jun 21 2024

.SYNOPSIS...

An area of low pressure over offshore waters will continue to move
northwestward towards the southeast GA coast through tonight.
There is a chance for this low to develop into a tropical
depression prior to moving onshore, but development into a
tropical cyclone is not expected at this time. Strong high
pressure ridging situated from the northeast has resulted in an
increased pressure gradient, which will persist small craft
advisory conditions through at least this evening before low
pressure weakens onshore tonight. High pressure relaxes over
waters this weekend and into the start of next week, with a more
typical summer sea breeze-like pattern returning.
