AMZ400-162115- Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm- 928 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 today, 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. .GULF STREAM...
