Isaac soaks Louisiana

Parts of Louisiana are soaked. Slidell, north of New Orleans, the roads look more like canals. Trees tops could be seen above the

flooding in this Plaquemines parish --- south of the New Orleans.

While Isaac has been downgraded from a hurricane to a tropical depression, Louisiana officials say it isn't over yet.

SOUNDBITE: Mayor Mitch Landrieu saying:

"The game is not over until the game is over and a lot of stuff can still happen. (EDIT) I know a lot of you are cooped up in your homes without power. I know what that is like."

Authorities say they are in the process of evacuating at least 60,000 people in Louisiana and Mississippi.
