617 FZUS54 KLCH 151946 CWFLCH Coastal Waters Forecast National Weather Service Lake Charles LA 246 PM CDT Sat Jun 15 2024 Coastal waters from the Lower Atchafalaya River LA to High Island TX out 60 nautical miles including Sabine and Calcasieu Lakes and Vermilion and Cote Blanche Bays Seas are provided as a range of the average height of the highest one third of the waves, along with the occasional height of the average highest ten percent of the waves. GMZ400-161015- 246 PM CDT Sat Jun 15 2024 .SYNOPSIS... Weak high pressure will bring about mainly light easterly winds into Sunday. A trough will gradually move west across the southern Gulf of Mexico from early to mid week. Deep moisture will be associated with this system that will bring widespread shower activity. The gradient between the trough and high pressure to the northeast will bring moderate to strong east to southeast winds at or above 20 knots by Monday, that will continue through mid week. This prolonged wind field will allow for a significant increase in wave heights and swells. Small craft advisories will likely be needed during this period. Also, tides will be 1 to 2 feet above normal predicted levels that may lead to coastal flooding. $$ GMZ430-161015- Sabine Lake- 246 PM CDT Sat Jun 15 2024 .TONIGHT...South winds 5 to 10 knots, becoming southeast late.
