Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
154 AM EDT Wed Jun 19 2024

.SYNOPSIS...

Strong high pressure will remain anchored off coastal New England
through Thursday maintaining small craft advisory level onshore
winds and waves across the coastal waters. Meanwhile, a trough
situated to the northeast of the Bahamas will be steered westward
towards the southeastern seaboard late this week, with weak low
pressure possibly developing as this system traverses the Gulf
Stream waters. Showers and thunderstorms are expected to increase
in coverage late this week and through the upcoming weekend across
our local waters. High pressure will weaken late this week as it
sinks slowly southward towards Bermuda, with the axis of this
surface ridge extending across our area during the upcoming
weekend. Winds and seas will gradually diminish as prevailing
winds shift to southeasterly on Saturday and then southerly by
Sunday.
