Heavy rain, high winds and floodwaters swept over Louisiana and Mississippi on Wednesday, as Isaac was downgraded from a hurricane to a tropical storm and a fortified levee system appeared to have saved New Orleans from disaster.
Rescuers picked up dozens of residents who had ignored warnings to leave low-lying areas, seven years to the day after hurricane Katrina devastated the city.
Power lines were cut and debris littered the streets, prompting authorities in New Orleans to declare a dusk-to-dawn curfew. Louisiana officials said they would intentionally breach a levee in Placquemines parish, south of New Orleans, as Isaac lumbered inland from the Gulf of Mexico.
Authorities feared many residents would need help after a night of torrential rain and harsh winds knocked out power to more than 700,000 households and businesses.
