Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
200 PM EDT Sun Jun 16 2024

.SYNOPSIS...

High pressure centered over New England will strengthen as it
moves slowly offshore this evening. This feature will result in
strengthening easterly winds late this afternoon and evening
throughout our local waters, with winds and seas continuing to
gradually increase early this week. Small Craft Advisory
conditions are expected to begin both near shore and offshore on
Tuesday. A low pressure center is expected to develop over the
southwestern Atlantic Ocean early this week, with this feature
gradually organizing around midweek as it moves westward across
the Bahamas, with a low risk for tropical development as this
system approaches our local waters on Thursday and Thursday night.
Coverage of showers and thunderstorms will gradually increase
across our local waters towards midweek, with widespread activity
likely by late week.
