.Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote
Blanche Bays...
Dense fog will slowly erode through the mid mornings hours along the
lakes, bays, and nearshore waters. Light to moderate east to
southeast flow continues until the passage of a cold front tonight.
Winds will veer southwest to west through the afternoon, then turn
quickly offshore and strengthen into early Fri morning when a brief
Small Craft Advisory may be needed. A return to onshore flow occurs
Friday night with warm moist air moving inland once again to the
rest of the period.
Cool shelf waters combined with warm moisture return and mostly calm
conditions will likely bring back the occurrence of marine fog by
the weekend through much of next week.
