752 FZUS54 KLIX 241037 CWFLIX Coastal Waters Forecast National Weather Service New Orleans LA 437 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-GMZ501-242300- 437 AM CST Mon Nov 24 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Broad surface ridge centered over the Ohio River Valley is steadily moving eastward. As it does so, offshore winds will be rotating around to east and then southeast through the early morning hours. Farther west, an upper level low is located near the 4-Corners region. It will be quickly moving eastward and into the Central Plains by late in the day today. A surface low will develop in the vicinity of the upper low and follow its path into OK and KS. The local pressure gradient will tighten in response to that feature. Thus, expect the southerly winds to increase to at least Exercise Caution speeds from west to east over the coastal waters late this aftn/evn. Models show BL winds peaking in the low 20s around 06Z on Tuesday and quickly falling off to 15kts or less by mid morning Tuesday. May need to issue a short term Small Craft Advisory for open Gulf waters. 48 hours after that, another (stronger) cold front will push through the region. The upper trough looks to be much deeper and broader which will likely translate to stronger winds that persist longer than 12 hrs. $$ GMZ530-242300- Lake Pontchartrain and Lake Maurepas- 437 AM CST Mon Nov 24 2025 .TODAY...Southeast winds 5 to 10 knots.
