Coastal Waters Forecast for Northeast Florida/Southeast Georgia

National Weather Service Jacksonville FL

Atlantic Coastal Waters from Altamaha Sound GA to Flagler Beach FL out to 60 nm. Seas are provided as a range of the average height of the highest 1/3 of the waves, along with the occasional height of the average highest 1/10 of the waves. Gusty Northwest flow is expected through tonight in the wake of arctic cold frontal passage with Small Craft Advisory conditions along with occasional gusts to gale force. Arctic high pressure building along the northern Gulf coast in the wake of this cold frontal passage will remain centered to the west of our our region through Tuesday, keeping breezy northwest to northerly winds and elevated seas in place. High pressure will then shift eastward towards the Carolina coast on Tuesday night, allowing winds to shift to northeasterly across our local waters. Coastal troughing will develop on Wednesday over our near shore waters, with this feature then lifting northward in advance of a weak frontal boundary that will be entering the southeastern states on Thursday. A few showers will be possible along and ahead of this approaching front from Wednesday night through early Friday morning. .GULF STREAM.
