Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
224 AM EDT Tue Jul 21 2026
.SYNOPSIS...
Breezy southerly winds between the tropical storm Bertha and the
Bermuda high will lead a couple more days of breezy conditions.
Winds will increase to Small Craft Advisory levels this afternoon
and remain elevated through early Wednesday. Seas will rise toward
5
or possibly 6 feet today in response to the winds. Relaxing winds
are expected Wednesday night as flow generally trends offshore as a
weak cold front approaches from the northwest. The front is likely
to stalls north of the waters this weekend as waves of low pressure
track along it. Though offshore flow will be in place from Thursday
onward, afternoon winds in nearshore waters will be driven by the
coastal sea breeze development each afternoon.
