Breezy northeasterly winds  will gradually diminish by this evening. A developing winter storm  system over the central and southern United States late this week and  Arctic high pressure building to the north of our region will drive  a cold front south across our waters on Friday night and Saturday,  with a surge of northeast winds expected to briefly overspread  our local waters from north to south early this weekend. A wave of  low pressure then develops along this boundary near our region by  Saturday night and Sunday. This storm system's warm front will  lift northeast across our local waters on Sunday. Another cold  front will cross our local waters by Sunday night and Monday, with  strengthening north winds forecast in the wake of this frontal  passage early next week.    .GULF STREAM...    The approximate location of the west wall of the Gulf Stream as of  Jan 20, 2026 at 0000 UTC...    50 nautical miles east of Flagler Beach.  53 nautical miles east of Saint Augustine Beach.  64 nautical miles east southeast of Jacksonville Beach.  76 nautical miles east southeast of St Simons Island.    This data derived from NCEP Global RTOFS model.    $$
