Katrina Update: Water rises in NOLA as pumps fail

Parts of New Orleans are flooded with up to six feet of water after some of the pumps that protect the low-lying city failed under the onslaught from Hurricane Katrina. New Orleans Mayor Ray Nagin stated the Lower 9th Ward of New Orleans, on the east side of the city, was under five to six feet of rising water after three pumps failed. National Weather Service has also declared "total structural failure" in some parts of metropolitan New Orleans. About 50 minutes ago, as the western eye wall was passing over the city, Katrina was downgraded to a Category 3 storm with winds up to 120 miles per hour. The storm's eastern eye wall was approaching Biloxi and Gulfport, Mississippi, where roofs were being pulled off of structures and boats were floating in the streets.
