A broad surface high centered over the area will keep benign conditions in place across the waters through Tuesday with light and variable winds of less than 5 knots and seas of less than 2 feet expected. A few showers or storms will pop up in the morning hours with some locally higher winds and waves possible as well as lightning and waterspouts especially on Wednesday morning. The pressure gradient will begin tightening Wednesday morning behind a backdoor front. This will cause easterly winds to increase to 15 to 25 knots with gusts upwards of 30 knots midday Wednesday through Thursday. A Small Craft Advisory is in effect Wednesday night into Thursday night. Seas will respond to these higher winds and increase to 6 to 9 feet in the open Gulf waters. These unsettled marine conditions will gradually abate late Friday and into Saturday. $$ GMZ529-160700- Lake Maurepas- 156 PM CDT Tue Sep 15 2026 ...SMALL CRAFT ADVISORY IN EFFECT FROM WEDNESDAY MORNING THROUGH THURSDAY AFTERNOON... .THIS AFTERNOON...Southeast winds around 5 knots.
