.DAY ONE...Today and Tonight

A Coastal Flood Advisory remains in effect for all of coastal
Southeast Louisiana including around Lake Pontchartrain and

Strong onshore winds of 20 to 25 knots and very rough seas will
continue in the coastal waters through this afternoon. Small
Craft Advisories are in effect for all of the waters.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Scattered to numerous thunderstorms will be possible Saturday and
