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. High pressure centered near the Florida panhandle coast will shift southeastward towards the Florida peninsula on Friday afternoon and evening as low pressure moves eastward across the Ohio Valley and off the Mid-Atlantic coast by late Friday night. Westerly winds will briefly strengthen to Caution levels as this storm system passes well to the north of our local waters late Friday night and Saturday morning. High pressure will remain situated over the Florida peninsula this weekend, allowing for winds and seas to subside. High pressure will then weaken and slide southeastward on Sunday night ahead of a strong cold front, which may bring a few showers to our local waters, mainly on Monday afternoon and evening. Southwesterly winds will develop ahead of this approaching front on Sunday evening, followed by winds shifting to westerly on Monday evening as the front crosses our region, with speeds increasing to Caution levels before midnight and then strengthening to Small Craft Advisory levels after midnight as winds shift to northwesterly. Northwesterly winds will continue in the wake of this frontal passage for much of next week, with breezy conditions expected on Tuesday and Wednesday as high pressure builds eastward along the northern Gulf coast. High pressure will then gradually weaken as it shifts towards our area by New Year's Eve, allowing winds and seas to gradually subside. .GULF STREAM.
