One person confirmed dead in Hurricane Isaac
One person is confirmed dead as Hurricane Isaac comes ashore in the United States, toppling trees and knocking out power to hundreds of thousands of homes and businesses around Louisiana.
Isaac, a vast storm that tore through southeastern Louisiana on the anniversary of Hurricane Katrina, weakened from a hurricane to a tropical storm after pushing floodwaters over a levee in marshy Plaquemines Parish and forcing the dramatic rescue of dozens of stranded residents.
