Not "Walking on Sunshine."

I guess we'll never think of Katrina and the Waves the same way again. Say a prayer for New Orleans:

"This is a once in a lifetime event," the mayor said. "The city of New Orleans has never seen a hurricane of this magnitude hit it directly."

The mayor said Katrina's storm surge would likely top the levees that protect the city from the surrounding water of Lake Pontchartrain, the Mississippi River and marshes. The bowl-shaped city must pump water out even during normal times, and the hurricane threatened electricity that runs the pumps.
