Tune in to FOX News Channel this Saturday and Sunday at 10 p.m. and 1 a.m. ET as award-winning and veteran journalist Geraldo Rivera brings you two special broadcasts this weekend!

Police officers and soldiers did another house-to-house sweep of hurricane-ravaged New Orleans (search) Friday to try to convince those still clinging to their homes to evacuate, and what they saw raised hopes that the city's death toll could be much lower than projected.

Meanwhile, Federal Emergency Management Agency Director Michael Brown (search) will return to Washington to oversee national Hurricane Katrina relief efforts. In his place, Coast Guard Vice Adm. Thad W. Allen (search) will oversee relief and rescue efforts.

We'll get an update on rescue and recovery efforts from Omar Landrum of the Louisiana State Police.

How hard will it be for authorities to identify the scores of dead that they expect to find once the full scale of Katrina's devastation is known? Forensic pathologist, Dr. Michael Baden, offers insight.

What steps are being taken to prevent a major medical crisis along the Gulf Coast? Dr. Manny Alvarez, FOX News medical contributor, weighs in.

Who will care for the animals — domestic and otherwise — made homeless by Katrina? We'll ask Jack Hanna, director of the Columbus Zoo.

Did race play a role in who was rescued in New Orleans? We'll ask Rev. Al Sharpton.

Plus, could we see another catastrophic hurricane this season? We'll get a read from Accuweather's Jim Kosek.

And, we'll be joined by Ernie Allen of the National Center for Missing and Exploited Children.

Then, how are authorities restoring order to a lawless city? We'll ask Bernie Kerik, former commissioner of the New York City Police Department.

Those stories and much more!
