   AMZ400-012230-  Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-  230 AM EST Mon Mar 1 2021      .SYNOPSIS...  A cold front entering the southeastern states early this morning  will race southeastward, moving through the Georgia waters late  this afternoon and the northeast Florida waters this evening,  accompanied by showers and possibly a few thunderstorms.  Meanwhile, strong high pressure building over the Ohio Valley  tonight in the wake of the frontal passage will wedge down the  southeastern seaboard tonight, resulting in a surge of  northeasterly winds and Small Craft Advisory conditions  overspreading our waters from north to south late tonight and  Tuesday morning. Meanwhile, low pressure will develop along the  northern Gulf coast early on Tuesday and will move east-  northeastward across the Florida panhandle and southern Georgia on  Tuesday night and Wednesday morning, dragging another cold front  across our waters towards noon on Wednesday, accompanied by  showers and thunderstorms. Low pressure will continue to  strengthen as it moves off the Carolina coast on Wednesday night  as high pressure builds into the lower Mississippi Valley,  resulting in breezy northwesterly winds shifting to northerly  before sunrise on Thursday. Stronger high pressure will then build  over the Ohio Valley late this week, bringing another round of  northeasterly winds to our waters by Friday.    .GULF STREAM...    The approximate location of the west wall of the Gulf Stream as of  Feb 27, 2021 at 1200 UTC...    64 nautical miles east of Flagler Beach.  72 nautical miles east of Saint Augustine Beach.  85 nautical miles east southeast of Jacksonville Beach.  99 nautical miles east southeast of St Simons Island.    This data courtesy of the Naval Oceanographic Office.      $$
