 .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 Marine Dense Fog Advisory continues for the lakes and bays as
 well as nearshore waters through 18Z today due to ongoing and
 expected continuance of a coastal fog bank. Onshore flow should
 increase just enough by midday to scattered out some of this fog,
 but likely won't allow it to dissipate fully. With very warm,
 moist air lingering over the coastal waters,through the end of the
 week, any fog that does dissipate this afternoon will likely
 redevelop by sunset tonight, with another Dense Fog Advisory
 likely being required. This trend should continue until the
 passage of a cold front Fri/Fri night, that will bring a steady
 influx of drier air through the weekend into early next week.
