   AMZ400-030400-  Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-  855 AM EDT Thu Apr 2 2026      .SYNOPSIS...    Small Craft Exercise Caution level seas are expected to develop over  the offshore waters adjacent to northeast Florida this afternoon as  a trough moves westward, increasing wind speeds slightly and  generating scattered showers and a few embedded thunderstorms  through Friday. Elevated seas will persist across the offshore  waters adjacent to northeast Florida through Friday night. A cold  front will enter the southeastern states late this weekend, likely  crossing our local waters on Monday morning, accompanied by showers  and thunderstorms. Strong high pressure building north of the area  will then wedge down the southeastern seaboard during the early to  middle portions of next week, likely create a surge of strong  northeasterly winds and building seas across our local waters, with  Small Craft Advisory conditions becoming increasingly likely for  much of the week.    .GULF STREAM...    The approximate location of the west wall of the Gulf Stream as of  Apr 01, 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.  71 nautical miles east southeast of St Simons Island.    This data derived from NCEP Global RTOFS model.      $$
