Dr. Max Mayfield, director of the National Hurricane Center, said Sunday that officials with the Federal Emergency Management Agency and the Department of Homeland Security, including FEMA Director Mike Brown and Homeland Security Secretary Michael Chertoff, listened in on electronic briefings given by his staff in advance of Hurricane Katrina slamming Louisiana and Mississippi and were advised of the storm’s potential deadly effects.

“We were briefing them way before landfall,” Mayfield said. “It’s not like this was a surprise. We had in the advisories that the levee could be topped.

“I keep looking back to see if there was anything else we could have done, and I just don’t know what it would be,” he said.

Chertoff told reporters Saturday that government officials had not expected the damaging combination of a powerful hurricane levee breaches that flooded New Orleans.

... In the days before Katrina hit, Mayfield said, his staff also briefed FEMA, which under the Department of Homeland Security, at FEMA’s headquarters in Washington, D.C., its Region 6 office in Dallas and the Region 4 office in Atlanta about the potential effects of the storm.

He said all of those briefings were logged in the hurricane center’s records.

... FEMA’s own July 23, 2004, news release announcing the end of that exercise summed up the assumptions they used, which were eerily close to what Katrina delivered:
“Hurricane Pam brought sustained winds of 120 mph, up to 20 inches of rain in parts of southeast Louisiana and storm surge that topped levees in the New Orleans area. More than one million residents evacuated and Hurricane Pam destroyed 500,000-600,000 buildings. Emergency officials from 50 parish, state, federal and volunteer organizations faced this scenario during a five-day exercise held this week at the State Emergency Operations Center in Baton Rouge.

“The exercise used realistic weather and damage information developed by the National Weather Service, the U.S. Army Corps of Engineers, the LSU Hurricane Center and other state and federal agencies to help officials develop joint response plans for a catastrophic hurricane in Louisiana.”
