GMZ500-GMZ501-040600- 1127 AM CST Wed Dec 3 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Weak low pressure will be developing along the Texas coast this afternoon/evening and slowly drift east-northeast Thursday along the coast. This will tighten the pressure gradient especially east of the Mississippi River delta. Winds will increase with moderate to strong east-southeast to easterly winds. This will have multiple impacts with Small Craft Advisory conditions expected Thursday into Friday but the increase in onshore winds will combine with the increasing tidal cycle at the end of the week likely leading to at least some minor coastal flooding. Main concern will be east facing shores of Orleans, St Bernard, Plaquemines, and far southeastern St Tammany. In addition coastal Hancock around Waveland will also deal with some minor coastal flooding Thursday night through Friday morning. Winds will relax and return to offshore late Friday and Friday night but another weak surface low will develop Saturday moving across the coastal waters late Saturday bringing another brief period of moderate to strong winds. $$ GMZ530-040600- Lake Pontchartrain and Lake Maurepas- 1127 AM CST Wed Dec 3 2025 ...SMALL CRAFT EXERCISE CAUTION IN EFFECT FROM THURSDAY MORNING THROUGH LATE THURSDAY NIGHT... .THIS AFTERNOON...East winds around 5 knots.
