NEW ORLEANS (AP) - Louisiana residents still reeling from flooding and damage caused by Hurricane Ida scrambled for food, gas, water and relief from the sweltering heat as thousands of line workers toiled to restore electricity and officials vowed to set up more sites where people could get free meals and cool off.

Power and water outages affected hundreds of thousands of people, many of them with no way to get immediate relief.

“I don’t have a car. I don’t have no choice but to stay,” said Charles Harris, 58, as he looked for a place to eat Tuesday in a New Orleans’ neighborhood where Ida snapped utility poles and brought down power lines two days earlier.

Harris had no access to a generator and said the heat was starting to wear him down. New Orleans and the rest of the region were under a heat advisory, with forecasters saying the combination of high temperatures and humidity could make it feel like 106 degrees Fahrenheit on Wednesday.

New Orleans officials announced seven places around the city where people could get a meal and sit in air conditioning.

The city was also using 70 transit buses as cooling sites and will have drive-thru food, water and ice distribution locations set up on Wednesday, Mayor LaToya Cantrell said. Louisiana Gov. John Bel Edwards said state officials also were working to set up distribution locations in other areas around the state.

Cantrell ordered a nighttime curfew Tuesday, calling it an effort to prevent crime after Hurricane Ida left the entire city without power.

Police Chief Shaun Ferguson said there had been some arrests for stealing.

The mayor, additionally, said she expects the main power company, Entergy, to be able to provide some electricity to the city by Wednesday evening, though she stressed that doesn’t mean a quick citywide restoration. Entergy was looking at two options to “begin powering critical infrastructure in the area such as hospitals, nursing homes and first responders,” the company said in a news release.

Cantrell acknowledged there would frustration in the days ahead.

“We know it’s hot. We know we do not have any power, and that continues to be a priority,” she told a news conference.

The New Orleans airport, closed since the storm hit, planned to reopen Wednesday for “very limited” flights, an airport statement said. Only American Airlines had flights scheduled Wednesday, but officials “hope for more normal operations later in the week,” it said.

Edwards on Tuesday surveyed damage from the storm, which caused massive flooding and structure damage in Houma, LaPlace and other communities outside New Orleans.

The barrier island of Grand Isle, which bore Ida’s full fury, is “uninhabitable,” with every building damaged, Jefferson Parish President Cynthia Lee Sheng told a news conference. There are also numerous breaks in the levee system and a strong odor of natural gas, she said.

The number of deaths from the hurricane climbed to at least four in Louisiana and Mississippi, including two people killed Monday night when seven vehicles plunged into a 20-foot-deep hole near Lucedale, Mississippi, where a highway had collapsed after torrential rains.

Edwards said he expects the death toll to rise.

More than 1 million homes and businesses in Louisiana and Mississippi were left without power when Ida slammed the electric grid on Sunday with its 150 mph winds, toppling a major transmission tower and knocking out thousands of miles of lines and hundreds of substations.

An estimated 25,000-plus utility workers labored to restore electricity, but officials said it could take weeks.
