GMZ400-011800- 1136 PM CST Sun Nov 30 2025 .Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote Blanche Bays... A Small Craft Advisory remains in effect for all of our coastal waters as strong cold air advection behind the front continues. There will be a short break from the wind Monday afternoon until the next cold front moves offshore causing north winds around 20 knots and gusts of 25 knots. A second small craft advisory will be in place late Monday night until Tuesday afternoon. Altimeter data has lined up well with model guidance with wave heights between 5 and 6 feet in the outer waters and 2 to 4 feet in the inner coastal waters. With low tide on Tuesday we could need a low water advisory as water levels will drop between -0.5 to -1.0 feet below MLLW. $$ GMZ430-011800- Sabine Lake- 1136 PM CST Sun Nov 30 2025 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH MONDAY MORNING... .TODAY...North winds 10 to 15 knots, increasing to 15 to 20 knots this afternoon.
