This satellite image released by NOAA on Sunday Aug. 31, 2008 shows Hurricane Gustav moving northwest towards the Gulf Coast. The storm was set to crash ashore late Monday morning with frightful force, testing the three years of planning and rebuilding that followed Katrina's devastating blow to the Gulf Coast.
