NWS Marine Forecast


   GMZ500-GMZ501-180515-  1007 AM CST Mon Nov 17 2025      .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...    Surface high pressure will generally remain east of the local area  through early week. This will keep flow oriented onshore and fairly  light through mid week. Late week, the pressure gradient will  tighten as a surface low develops over West Texas and moves through  the southern portion of the Central Plains. Onshore winds will  strengthen in response to this. Guidance suggests winds of around  15- 20 knots in open Gulf waters Thursday and Friday which would  subsequently bring seas to 3-6 feet. Model consistency has not been  the greatest with this late week system, but regardless an increase  in flow seems likely.    $$
