NWS Marine Forecast


   GMZ500-GMZ501-031800-  1127 PM CST Tue Dec 2 2025      .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...    High pressure has moved in but will continue to sliding east quickly  leading to light return flow by midday/early afternoon today. Weak  low pressure will begin to develop along the Texas coast tonight and  slowly drift east-northeast Thursday along the coast. This will  tighten the pressure gradient especially east of the Mississippi  River delta. Winds will increase with moderate to strong east-  southeast to easterly winds. This will have multiple impacts with  Small Craft Advisory conditions expected Thursday into Friday but  the increase in onshore winds will combine with the increasing tidal  cycle at the end of the week likely leading to at least some minor  coastal flooding. Main concern will be east facing shores of  Orleans, St Bernard, Plaquemines, and far southeastern St Tammany.  In addition coastal Hancock around Waveland will also deal with some  minor coastal flooding Thursday night through Friday morning. Winds  will relax and return to offshore late Friday and Friday night but  another weak surface low will develop Saturday moving across the  coastal waters late Saturday bringing another brief period of  moderate to strong winds.    $$
