Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
226 AM EDT Sat Jun 13 2026
.SYNOPSIS...
A lingering trough north of the waters and ridging to the south will
continue offshore breezes this morning. There will be a chance of
showers and isolated thunderstorms near the coastline this afternoon
but minimal activity is expected over the open waters. Another front
pushes into the southeastern US Sunday night and will stall and
eventually dissipate there through the first half of the upcoming
week. This will promote nightly southwesterly wind surges to
Exercise Caution levels, mainly offshore. Strengthening offshore
flow next week will increase chances for afternoon thunderstorms
across the coastal waters.
