GMZ400-040700- 1214 PM CST Sat Jan 3 2026 .Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote Blanche Bays... Enhanced low tide cycle will keep Low Water concerns and advisories in effect through the weekend. Cold front is now moving offshore this afternoon. Hazardous seas will remain enhanced through the afternoon until north regime helps swells abate. This period of elevated offshore winds will keep seas elevated for southeast waters until sundown. Additionally such a reverse in flow could lead to choppy conditions overnight into Sunday while falling under advisory criteria. Winds remain offshore until late Sunday when high pressure moves east and onshore winds can resume. Potential for inland fog bleeding into coastal waterways and lakes does increase early in the week with said return of onshore flow. 30 $$ GMZ430-040700- Sabine Lake- 1214 PM CST Sat Jan 3 2026 ...LOW WATER ADVISORY IN EFFECT UNTIL 2 PM CST THIS AFTERNOON... .TONIGHT...North winds 10 to 15 knots.
