GMZ400-110600- 1158 AM CST Mon Nov 10 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... Winds continue to weaken as the cold front moves into the southern Gulf. Even with the weaker winds, the latest ASCAT pass shows a large swath of 20-knot winds from the north. With those winds still in the area, we will start to pare down the Small Craft Advisory until the last segments in the eastern waters expire at 9 PM. With the continued winds, the Low Water Advisory will go through the next low tide and then expire at 3 PM. Starting on Tuesday, winds will be light and onshore, and waves will fall in response, staying below 3 feet through the end of the week. $$ GMZ430-110600- Sabine Lake- 1158 AM CST Mon Nov 10 2025 ...LOW WATER ADVISORY IN EFFECT UNTIL 3 PM CST THIS AFTERNOON... .TONIGHT...North winds 5 to 10 knots, becoming northeast after midnight.
