NEW ORLEANS — Tens of thousands of customers remained in the dark Monday in Louisiana and Mississippi, days after Isaac inundated the Gulf Coast with a deluge that still has some low-lying areas under water.
Most of those were in Louisiana, where utilities reported more than 100,000 people without power as of Monday morning. Thousands also were without power in Mississippi and Arkansas.
Thousands of evacuees remained at shelters or bunked with friends or relatives.
"My family is split up," said Angela Serpas, from severely flooded Braithwaite in Plaquemines Parish. Serpas and her daughter were staying with her in-laws while her husband and son were staying in Belle Chasse, a suburban area of the parish.
"This is the second time we've lost our home. We lost it in Katrina," she said.
Meanwhile, inspectors from the Federal Emergency Management Agency are out trying to get a handle on losses. Residents can apply for grants to get help with home repairs and temporary housing, among other expenses.
President Barack Obama visited Louisiana on Monday, a day ahead of the Democratic National Convention. Republican presidential nominee Mitt Romney visited the state Friday. Obama's Homeland Security Secretary, Janet Napolitano, visited Bay St. Louis, Miss., and Slidell, La., on Sunday.
"We are part of a team to make sure Hurricane Isaac is put to rest as soon as we can for all those affected," Napolitano said. "In the meantime, please know all of us are thinking about those in Louisiana who are without their homes or without their businesses."
At least seven people were killed in the storm in the U.S. — five in Louisiana and two in Mississippi.
More than 2,800 people were registered at various state, local and Red Cross shelters in Louisiana, down from around 4,000 earlier. State officials were uncertain how many people would eventually need longer-term temporary housing. Kevin Davis, head of the state's emergency office, said that housing would likely include hotels at first, then rental homes as close as possible to their damaged property.
Progress was evident in many places, though lingering flooding remained a problem in low-lying areas.
Crews in the town of Lafitte intentionally breached a levee Sunday night in an effort to help flooding there subside, Jefferson Parish Councilman Chris Roberts told The Times-Picayune.
