The critical task for Army engineers: Can they repair the levees before the deadly flow of water submerges all of New Orleans? Team FOX is live with the latest.

First the levees broke, unleashing walls of water into the heart of New Orleans. Now that water is mixing with sewage and other pollutants creating what could be a toxic situation. So how can the Crescent City possibly clean up and restore a mess of this magnitude? We'll get insight from Ivor Van Heerden, director of LSU's Center for the Study of Public Health Impacts of Hurricanes.

And, New Orleans is turning violent in the wake of Katrina. Fights and fires break out; dead bodies in the streets; police officers shot at. The city's mayor is now appealing for help, calling it a "desperate SOS." So what will it take to restore order to New Orleans? We'll ask retired U.S. Army Maj. Gen. Bob Scales and former NYC Police Commissioner Bernard Kerik.

Plus, Louisiana Sen. Mary Landrieu says there could be thousands of people dead in her state. We'll talk with Sen. Landrieu about the devastating situation.

Real journalism: fair and balanced. That's why we're No. 1 — FOX News Channel.
