New Orleans (AP) - Isaac's whistling winds lashed the city and the storm dumped nearly a foot of rain on its desolate streets, but the system of levee pumps, walls and gates appeared to withstand one of the stiffest challenges yet. To the north and south, though, people had to be evacuated or rescued as Isaac lingered over Louisiana.
The rain fell almost constantly for more than a day, flooding neighborhoods in a rural part of the state and in neighboring Mississippi. Officials had to respond quickly because the waters were rising fast even as Isaac meandered slowly northward Thursday on a path toward Arkansas.
President Barack Obama declared federal emergencies in Louisiana and Mississippi late Wednesday, according to a statement from the White House. The disaster declarations free up federal aid for affected areas.
Along the shores of Lake Ponchartrain, officials sent scores of buses and dozens of high-water vehicles to help evacuate about 3,000 people as rising waters lapped against houses and left cars stranded. Floodwaters rose waist-high in some neighborhoods, and the Louisiana National Guard was working with sheriff's deputies to rescue people stranded in their homes.
The floodwaters "were shockingly fast-rising, from what I understand from talking to people," Lt. Gov. Jay Dardenne said. "It caught everybody by surprise."
Isaac arrived 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.
"Unfortunately, that's not been the case for low-lying areas outside the federal system, in particular lower Jefferson and Plaquemines parishes," said Louisiana Democratic US. Sen. Mary Landrieu. "Hurricane Isaac has reinforced for us once again just how vulnerable these critical areas are. We must re-engage the Corps of Engineers on this."
New Orleans' biggest problems seemed to be downed power lines, scattered tree limbs and minor flooding. One person was reported killed, compared with 1,800 deaths from Katrina in Louisiana and Mississippi. And police reported few problems with looting. New Orleans Mayor Mitch Landrieu ordered a dusk-to-dawn curfew.
