A weak area of low pressure will gradually drift east across the Louisiana Coast on Thursday. 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. Winds will relax and return to offshore late Friday and then more variable on Saturday with the passage of another weak sfc low. A frontal passage on Sunday night will bring another push of strong offshore winds on Monday which could prompt small craft headlines for much of the coastal waters. $$ GMZ530-041800- Lake Pontchartrain and Lake Maurepas- 1122 PM CST Wed Dec 3 2025 ...SMALL CRAFT ADVISORY IN EFFECT FROM 6 AM CST THURSDAY THROUGH LATE THURSDAY NIGHT... .REST OF TONIGHT...East winds 10 to 15 knots.
