   AMZ400-280900-  Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-  227 PM EDT Mon Apr 27 2026      .SYNOPSIS...    Strong high pressure centered over the Mid-Atlantic states will  continue to push a frontal boundary southward down the Florida  peninsula. Strong northeasterly winds will persist across our local  waters through early this evening, creating Small Craft Advisory  conditions throughout the northeast Florida and offshore waters  adjacent to southeast Georgia through late this evening. High  pressure will then weaken as it slides southeastward on Tuesday,  becoming positioned off the southeastern seaboard, allowing for  onshore winds and seas to gradually subside through Tuesday night. A  cold front will then enter the southeastern states on Wednesday,  possibly bringing a few showers and thunderstorms to the Georgia  waters during the afternoon and evening hours. This front will then  slowly move across the rest of our local waters on Thursday and  Thursday evening, accompanied by showers and thunderstorms. This  front will briefly shift south of our region on Friday before a wave  of low pressure develops over the Gulf this weekend, likely  spreading additional showers and thunderstorms across our local  waters during the upcoming weekend.      .GULF STREAM...    The approximate location of the west wall of the Gulf Stream as of  Apr 27, 2026 at 0000 UTC...    54 nautical miles east of Flagler Beach.  62 nautical miles east of Saint Augustine Beach.  74 nautical miles east southeast of Jacksonville Beach.  80 nautical miles east southeast of St Simons Island.    This data derived from NCEP Global RTOFS model.      $$
