   AMZ400-030230-  Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-  726 AM EDT Sat May 2 2026      .SYNOPSIS...    Low pressure developing along a frontal boundary situated along the  northern Gulf coast will push across our local waters early this  afternoon. Widespread showers and thunderstorms will overspread our  local waters during the late morning and afternoon hours, with  strong to isolated severe storms possible through around sunset.  Stronger storms will be capable of producing strong wind gusts,  frequent lightning strikes, and possibly a few waterspouts.  Southwesterly winds will strengthen after sunrise, with speeds  likely reaching Caution levels as winds shift to westerly and then  northwesterly this afternoon. The front will shift south of our area  tonight, with gusty northerly winds expected after midnight as  lingering showers depart the northeast Florida waters. Breezy  northeast winds are then expected on Sunday as high pressure builds  into the southeastern states, with diminishing winds and seas  expected by early Sunday evening.    High pressure will shift offshore of the southeastern states early  next week, allowing for prevailing southeasterly winds. Breezy  conditions are likely on Wednesday afternoon well in advance of a  cold front that will be entering the southeastern states, with  Caution level speeds possible through Thursday as winds shift to  southerly and then southwesterly. Showers and thunderstorms will  likely accompany this next frontal passage on Thursday afternoon and  evening.      .GULF STREAM...    The approximate location of the west wall of the Gulf Stream as of  May 01, 2026 at 0000 UTC...    67 nautical miles east of Flagler Beach.  74 nautical miles east of Saint Augustine Beach.  88 nautical miles east southeast of Jacksonville Beach.  ... nautical miles east southeast of St Simons Island (Not Found).    This data derived from NCEP Global RTOFS model.      $$
