Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
256 AM EDT Sun Oct 5 2025

.SYNOPSIS...

High pressure centered along the Mid-Atlantic coast will continue to
wedge down the southeastern seaboard, while coastal troughing
remains situated over our near shore waters through Tuesday. Gusty
easterly winds and Small Craft Advisory conditions featuring rough,
elevated seas will continue across our local waters through Tuesday.
Meanwhile, waves of showers and a few embedded thunderstorms will
increase in coverage by Sunday night and Monday as weak low pressure
traversing the Bahamas moves towards southeast Florida. High
pressure will then shift further offshore of the Mid-Atlantic coast
by Tuesday night and Wednesday, allowing coastal troughing to weaken
over our local waters. A cold front entering the southeastern states
on Wednesday will then shift slowly southward across our local
waters by Thursday night and Friday. Strong northeasterly winds will
then redevelop late this week as another high pressure center
building over New England wedges down the southeastern seaboard.
