NWS Marine Forecast


   GMZ500-GMZ501-250600-  1127 AM CST Mon Nov 24 2025      .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...    A warm front located near the coast will move inland today as a cold  front approaches from the west. Ahead of the cold front, expect  scattered showers and thunderstorms across the coastal waters  beginning late tonight. A tightening pressure gradient will also  cause winds to strengthen and exercise caution headlines have been  issued for portions of the outer waters late tonight. The front will  finally move through the coastal waters Tuesday night, with high  pressure building over the area in its wake. The combination of cold  air advection over the relatively warm waters, and the pressure  gradient between the high and low will cause winds to strengthen  into the 20-25kt range and Small Craft Advisories will likely be  needed Wednesday afternoon through at least midday Thursday. As the  high settles into the area later in the week, winds will ease and  turn back to the southeast as the high shifts east of the area by  Saturday.    $$
