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. Ahead of an approaching cool front, onshore winds will veer southerly across the waters tonight through Sunday. The slowing front will gradually move north to south through the waters Sunday night bringing showers and isolated thunderstorms as the front stalls through Monday. In the wake of the front, high pressure will build to the north resulting in strengthening northeasterly winds Monday night and the onset of a multiday period of strong onshore winds throughout next week, likely requiring an extended Small Craft Advisory. Much stronger high pressure will wedge along the coast Wednesday resulting in further strengthening and potential for gales and seas building potentially up to 15 feet across the waters. As high pressure breaks away from the eastern seaboard late in the week, onshore winds will begin to relax. .GULF STREAM.
