Caution level speeds  will be possible on Wednesday afternoon and evening, well in advance  of a cold front that will be entering the southeastern states. Winds  will shift to southerly on Wednesday night and then southwesterly on  Thursday as the frontal boundary slowly approaches our local waters  from the northwest. Showers and thunderstorms will likely accompany  this frontal passage on Thursday afternoon and evening, with strong  storms possible across the Georgia waters. Breezy northwesterly  winds are expected in the wake of this frontal passage on Thursday  night, followed by winds shifting to northerly on Friday morning and  then northeasterly by Friday afternoon as the frontal boundary  likely stalls over the Florida peninsula. Additional rounds of  showers and thunderstorms will be possible from Friday through the  upcoming weekend as a wave of low pressure develops along the  stalled frontal boundary that should be positioned near the  northeast Florida waters.      .GULF STREAM...    The approximate location of the west wall of the Gulf Stream as of  May 03, 2026 at 0000 UTC...    58 nautical miles east of Flagler Beach.  70 nautical miles east of Saint Augustine Beach.  83 nautical miles east southeast of Jacksonville Beach.  94 nautical miles east southeast of St Simons Island.    This data derived from NCEP Global RTOFS model.      $$
