NWS Marine Forecast


   AMZ400-152145-  Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-  1005 AM EDT Sun Jun 15 2025      .SYNOPSIS...    Atlantic high pressure centered to the southeast of Bermuda will  continue to extend its axis westward across the Florida peninsula  through Monday, keeping a prevailing southerly wind flow across  our area. Afternoon sea breezes will increase wind speeds to near  Caution levels over the near shore waters late in the afternoon.  Showers and thunderstorms will impact our local waters during the  late afternoon and evening hours, with a few strong storms  possible, bringing briefly gusty winds, frequent lightning  strikes, and torrential downpours. Atlantic high pressure will  then lift its axis northward towards our local waters on Tuesday  and Wednesday, likely resulting in less afternoon and evening  thunderstorm coverage as southeasterly winds prevail. Atlantic  high pressure will then shift its axis southward across the  Florida peninsula late this week as a cold front enters the  southeastern states, resulting in prevailing southwesterly winds  and increasing chances for late afternoon and evening  thunderstorms by Friday.      .GULF STREAM...    The approximate location of the west wall of the Gulf Stream as of  Jun 14, 2025 at 1200 UTC...    64 nautical miles east of Flagler Beach.  74 nautical miles east of Saint Augustine Beach.  89 nautical miles east of Jacksonville Beach.  99 nautical miles east of St Simons Island.    This data courtesy of the Naval Oceanographic Office.    $$
