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. Weak low pressure organizing along the northern Gulf coast this afternoon will lift a warm front northeastward across our local waters on Friday, accompanied by showers and possibly an isolated thunderstorm. Weak low pressure will move northeastward across southeastern Georgia on Friday afternoon, with this storm system's cold front then crossing our local waters on Friday night and Saturday morning. A wave of low pressure will then develop along this front just south of the northeast Florida waters on Saturday night, with widespread rainfall and a few embedded thunderstorms likely across our local waters through Sunday. Low pressure will then strengthen as it moves offshore on Sunday night and Monday, resulting in strengthening north northwesterly winds as rainfall ends, with Small Craft Advisory conditions possible from Monday through early Tuesday. .GULF STREAM.
