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 trough will lift northward as a warm front today with increasing showers over the waters with afternoon isolated thunderstorms as a cold front approaches the region from the northwest. Winds from the southeast this morning will become southerly and increase exercise caution conditions offshore by this afternoon. Winds and seas will increase further over the Northeast Florida offshore waters to small Craft Advisory levels by mid afternoon with these conditions then spreading into the offshore Southeast GA waters by early evening. Winds will shift to westerly by Friday morning as a cold front moves through the waters, turning northwesterly and then northerly Friday afternoon into Friday evening. High pressure will settle over the local waters during the weekend, allowing for winds and seas to diminish. A weakening cold frontal boundary will approach our region from the north on Monday as strong high pressure builds to the north and wedges down the southeastern seaboard as another coastal trough develops over our local waters. This feature may develop showers over our local waters early next week. Small Craft Advisory conditions will likely develop after midnight on Sunday night as northeasterly winds surge, with elevated seas likely persisting through Tuesday as onshore winds only gradually subside. .GULF STREAM.
