Gusty  easterly winds and Small Craft Advisory conditions featuring rough,  elevated seas will continue across our local waters through Tuesday.  Meanwhile, waves of showers and a few embedded thunderstorms will  increase in coverage by Sunday night and Monday as weak low pressure  traversing the Bahamas moves towards southeast Florida. High  pressure will then shift further offshore of the Mid-Atlantic coast  by Tuesday night and Wednesday, allowing coastal troughing to weaken  over our local waters. A cold front entering the southeastern states  on Wednesday will then shift slowly southward across our local  waters by Thursday night and Friday. Strong northeasterly winds will  then redevelop late this week as another high pressure center  building over New England wedges down the southeastern seaboard.      .GULF STREAM...    The approximate location of the west wall of the Gulf Stream as of  Oct 04, 2025 at 1200 UTC...    57 nautical miles east of Flagler Beach.  66 nautical miles east of Saint Augustine Beach.  82 nautical miles east of Jacksonville Beach.  97 nautical miles east southeast of St Simons Island.    This data courtesy of the Naval Oceanographic Office.    $$
