NEW ORLEANS (AP) - Hurricane Isaac sidestepped New Orleans on Wednesday, sending the worst of its howling wind and heavy rain into a cluster of rural fishing villages that had few defenses against the slow-moving storm that could bring days of unending rain.
Isaac arrived exactly seven years after Hurricane Katrina and passed slightly to the west of New Orleans, where the city's fortified levee system easily handled the assault.
The city's biggest problems seemed to be downed power lines, scattered tree limbs and minor flooding. Just one person was reported killed, compared with 1,800 deaths from Katrina in Louisiana and Mississippi. And police reported few problems with looting. Mayor Mitch Landrieu ordered a dusk-to-dawn curfew just to be sure.

But in Plaquemines Parish, a sparsely populated area south of the city that is outside the federal levee system, dozens of people were stranded in flooded coastal areas and had to be rescued. The storm pushed water over an 18-mile levee and put so much pressure on it that authorities planned to intentionally puncture the floodwall to relieve the strain.
By midafternoon, Isaac had been downgraded to a tropical storm and the Louisiana National Guard wrapped up rescue operations in Plaquemines Parish, saying they felt confident they had gotten everyone out and there were no serious injuries.
Even at its strongest, Isaac was far weaker than Hurricane Katrina, which crippled New Orleans in 2005. Because Isaac's coiled bands of rain and wind were moving at only 5 mph - about the pace of a brisk walk - the threat of storm surges and flooding was expected to last into a second night as the immense comma-shaped system crawled across Louisiana.
The storm knocked out power to as many as 700,000 people, stripped branches off trees and flattened fields of sugar cane so completely that they looked as if a tank had driven over them.
