This image from NASA collected at 8:20 a.m EDT Monday, Aug. 29, 2005, shows Hurricane Katrina turning slightly eastward before slamming into shore. Hurricane Katrina plowed into New Orleans Monday with shrieking, 145-mph winds and blinding rain that flooded homes to the rooflines and peeled away part of the Superdome, where thousands of people had taken shelter.
