Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
737 AM EDT Tue Oct 20 2026
.SYNOPSIS...
Gusty northeast winds will continue to create hazardous seas
throughout the local waters as strengthening low pressure meanders
to the east of the North Carolina Outer Banks and high pressure
pushes down the east coast. Seas will slowly diminish across the
near shore waters adjacent to southeast Georgia by midweek as low
pressure begins to move away, while Small Craft Advisory level seas
will persist elsewhere through Friday. Another strong high pressure
center will then build out of the Great Lakes and New England on
Friday, and push north to northeast winds up to gale force by Friday
evening, keeping hazardous marine conditions in place through the
weekend.
