Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
845 AM EDT Sun May 31 2026
.SYNOPSIS...
Additional rounds of showers and thunderstorms are forecast from
Sunday 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.
