Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm
317 AM EDT Sat Apr 27 2024

SYNOPSIS

Strong high pressure centered along the New England and Mid
Atlantic coasts will continue to wedge down the southeastern seaboard through tonight, resulting in strengthening easterly winds this morning. Meanwhile, coastal troughing situated over the northeast Florida waters will continue to occasionally generate showers over our local waters today. This feature will shift inland this evening as high pressure begins to gradually weaken as it shifts southward towards the North Carolina Outer Banks. Small Craft Advisory conditions are expected to continue offshore through Sunday morning, while Small Craft Advisory conditions expand to the near shore waters adjacent to northeast Florida this afternoon and tonight. Winds and seas will diminish by Sunday evening as high pressure becomes anchored off the southeastern seaboard early next week, followed by prevailing winds shifting to southerly towards midweek.
