NWS Marine Forecast


   GMZ500-GMZ501-060100-  701 AM CDT Sun Oct 5 2025      .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...    Low pressure over the central Gulf and a high pressure system over  the eastern seaboard will keep a persistent easterly flow of 15 to  25 knots in place across all of the waters today. These winds will  also have a pretty long fetch across the eastern Gulf waters, and  this will support higher seas of up to 10 feet in the open Gulf  waters due to a combination of wind waves and swell. Small craft  advisories are in effect through the afternoon hours due to these  hazardous conditions. The high will start to become more dominant  over the waters on Monday and Tuesday, and this will allow the  easterly winds to relax a bit to between 10 and 15 knots. Seas will  also decrease to 2 to 4 feet as the winds relax. This brief respite  in rougher conditions will end on Wednesday and Thursday as the  pressure gradient again tightens over the Gulf. Easterly winds will  increase back to near advisory levels in the offshore waters and  seas will increase to 4 to 6 feet.    $$
