Coastal Waters Forecast for Northeast Florida/Southeast Georgia

National Weather Service Jacksonville FL

Southerly winds remain elevated ahead of an approaching cold front, creating Caution conditions throughout our local waters. Winds may subside slightly through early this morning before increasing winds from the south southwest into late this morning ahead of a line of strong thunderstorms approaching from the west. Showers and storms will impact our local waters during the early to mid afternoon hours, with a few stronger storms possible that could produce gusty winds and frequent lightning strikes. Winds will shift to westerly during the frontal passage before increasing northwest winds arrive this afternoon to small craft advisory levels followed by Gale conditions early this evening into early Friday as winds turn more north northeasterly as high pressure builds to the north. Winds and seas will remain elevated into Friday morning before subsiding Friday afternoon as high pressure shifts to the northeast. As the high moves away, a warm front will slowly lift northward along the Florida peninsula. Chances for showers and thunderstorms will begin to increase from south to north late Saturday night through Sunday night as this warm front moves across our area. A strong cold front will move through our area Monday, with southwest winds increasing and becoming northwesterly behind the front with small craft advisory conditions returning to the waters through Tuesday.
