Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
928 PM EDT Sun May 31 2026
.SYNOPSIS...
Additional rounds of showers and thunderstorms are forecast
tonight through Tuesday evening as a front stalls over our area
before a stronger cold front pushes southward across our local
waters on Tuesday night. Northeasterly winds will surge in the
wake of this frontal passage on Tuesday night as high pressure
building over the Ohio and Tennessee Valleys wedges down the
southeastern seaboard, creating Small Craft Advisory conditions
from late Tuesday night through at least Wednesday night
throughout our local waters. Breezy onshore winds and elevated
seas are expected through Thursday night as high pressure
gradually weakens over the southeastern states.
