NWS Marine Forecast


   GMZ500-GMZ501-312300-  536 AM CDT Sun May 31 2026      .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...    A broad area of high pressure will keep conditions over the waters  relatively benign. Winds will be light at 10 knots or less and seas  will remain below 2 feet. The seabreeze cycle will lead to some  variability in wind direction near the coast, and a few  thunderstorms could fire up in relation to this seabreeze/landbreeze  cycle. Any storms will be short-lived and will produce locally gusty  winds and lightning. A weak cold front is still expected to slip  into the waters Tuesday night into Wednesday. Winds will turn  northeasterly and increase to 10 to 15 knots in the wake of this  weak front. Thunderstorm activity will be a bit more widespread as  the front moves through, and a few stronger storms with high wind  gusts could develop. By Thursday and Friday, the front will  dissipate and a return to a prevailing southeast wind is expected.  However, the pressure gradient over the northern Gulf will tighten  up as a low forms over the western Gulf and a broad high remains  centered over the Southeastern states. This will push winds into the  15 to 20 knot range by the end of the week and seas will increase to  3 to 5 feet.    $$
