.Synopsis for Lower Atchafalaya River LA to High Island TX out

Blanche Bays...

High pressure centered over the northeastern gulf will ridge into
the coastal waters through the weekend into early next week. This
will keep mainly light onshore winds and low seas. Onshore flow
will increase somewhat by the middle part of next week as low
pressure forms over the Southern Plains. The next chance for any
significant shower activity will be Wednesday into Thursday ahead
