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. A weak coastal trough over the waters this evening, currently producing a few showers in the offshore waters, will lift away to the northeast later tonight. Patchy sea fog will be possible in early this morning. Otherwise, high pressure will be the dominant weather feature through the end of the week resulting in light winds and low seas across the local waters. Over the weekend, winds turn offshore and become breezy as a cold front approaches and passes Sunday night. High pressure building in behind the front will move offshore to the northeast early next week setting up onshore flow and development of a coastal trough. .GULF STREAM.
