Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
559 PM EDT Mon Jun 15 2026
.SYNOPSIS...
The region will be between high pressure to the south southeast, and
a frontal zone stalling just north of the local waters through most
of the upcoming week. This will lead to a predominant southwest
to west flow which will become breezy at times, with periods of
Small Craft Exercise Caution conditions, mainly over the offshore
waters. The offshore flow will continue to push strong storms with
gusty winds and frequent lightning into the coastal waters through
the period mainly in the afternoon hours. The frontal zone will
weaken mid week which will likely limit showers and thunderstorm
activity before another frontal boundary drops southward toward the
area Friday into Saturday.
