Like Camille II

Katrina has pretty much leveled the Louisiana/Mississippi coast and caused innumerable problems in New Orleans:

... The storm passed just east of New Orleans, straining the system of levees and pumping stations that protect the low-lying city. About 70 percent of the city sits below sea level.

The National Weather Service reported that water had overtopped levees in Orleans and St. Bernard parishes.

The Lower 9th Ward, on the east side of New Orleans was under five to six feet of rising water after three pumps failed, according to WGNO reporter Susan Roesgen, who is with New Orleans Mayor Ray Nagin. She said New Orleans police had received more than 100 reports of people trapped on their roofs.

The Associated Press reported that entire neighborhoods along the south shore of Lake Pontchartrain were flooded, and residents had scrambled onto the roofs of their shotgun-style houses.

"I'm not doing too good right now," Chris Robinson told the AP via cell phone from his home east of the city's downtown. "The water's rising pretty fast. I got a hammer and an ax and a crowbar, but I'm holding off on breaking through the roof until the last minute. Tell someone to come get me please. I want to live."
