092 FZUS54 KLIX 241727 CWFLIX Coastal Waters Forecast National Weather Service New Orleans LA 1127 AM CST Mon Nov 24 2025 Pascagoula to Atchafalaya River out to 60 NM Seas are provided as a range of the average height of the highest 1/3 of the waves...along with the occasional height of the average highest 10 percent of the waves. 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. $$ GMZ530-250600- Lake Pontchartrain and Lake Maurepas- 1127 AM CST Mon Nov 24 2025 .THIS AFTERNOON...Southeast winds 5 to 10 knots.
