Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
259 AM EDT Fri Oct 18 2024

.SYNOPSIS...

Strong high pressure centered over the Ohio Valley and the eastern
Great Lakes will continue to wedge down the southeastern seaboard,
creating strong northeasterly winds through the weekend and early
portions of next week. Meanwhile, coastal troughing taking shape
over the near shore waters adjacent to northeast Florida will
generate occasional showers beginning this afternoon and
continuing through early next week. Small Craft Advisory
conditions will remain ongoing offshore, with a surge in wind
speeds late this afternoon and evening bringing Small Craft
Advisory conditions to the near shore waters. Seas are expected to
build to Small Craft Advisory levels near shore beginning on
Saturday night, with elevated winds and seas expected near shore
through Monday. High pressure will then weaken as it settles
southward on Tuesday and Wednesday, allowing for winds and seas to
gradually subside.
