Officials in New Orleans say they are imposing a dusk-to-dawn curfew as Hurricane Isaac continues to lash the city on the seventh anniversary of Katrina.
Police cars have been patrolling the nearly empty streets since Isaac began bringing fierce winds and heavy rains to the city Tuesday night. The curfew was set to start Wednesday night and would last until further notice.
Rescuers in boats and trucks plucked a handful of people who became stranded by floodwaters in thinly populated areas of southeast Louisiana. Authorities feared many more could need help after a night of slashing rain and fierce winds that knocked out power to more than 600,000 households and businesses.
