Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
317 AM EDT Mon Sep 16 2024

.SYNOPSIS...

Potential Tropical Cyclone 8 will likely become a Tropical Storm
later this morning before pushing northwestward towards coastal
South Carolina this afternoon. Small Craft Advisory conditions
will continue throughout our local waters this morning, with
conditions improving over the near shore waters by this evening as
winds shift to northwesterly and diminish. Seas will then fall
below Small Craft Advisory criteria offshore by early Tuesday
morning. Otherwise, a leftover frontal boundary stretching across
central Florida will slowly lift northward across the northeast
Florida waters through midweek, possibly developing a few showers
and thunderstorms during the late afternoon and early evening
hours. Another surge of onshore winds will be possible towards
the weekend as strong high pressure wedges down the southeastern
seaboard.
