Coastal Waters Forecast for Northeast Florida/Southeast Georgia...UPDATED
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. High pressure positioned over coastal Georgia will weaken today as a a frontal boundary slowly pushes towards the southeastern states. Meanwhile, coastal troughing is situated offshore, but will weaken by Friday. Patchy fog with visibility of 1 NM or less is forecast along nearshore waters late tonight and Friday morning. Arctic high pressure will build northwest of the area on Friday and push the frontal boundary southward, crossing our local waters on Friday night. Northeast winds will briefly surge in the wake of this frontal passage on Saturday with a small craft advisory possible north waters. Meanwhile, a winter storm developing over Texas and the lower Mississippi Valleys on Saturday and Saturday night will shift northeast, lifting a warm front northward across our local waters on Saturday night. Winds will shift to south and then southwest on Sunday ahead of another cold front, which could be accompanied by a few thunderstorms on Sunday afternoon and night. Another Arctic high pressure center will then build into the southeast states in the wake of this cold frontal passage early next week, with Small Craft Advisory conditions expected as breezy northwest winds shift to north while strengthening further on Monday night.
