Of 27 electric substations in New Orleans, Mr. Green said, 13 are back online.
Mayor LaToya Cantrell, speaking at an afternoon briefing, noted that in addition to electricity, access to fuel continues to be a challenge for city residents. “We just have not received adequate fueling sources to the general public.” Ms. Cantrell promised that “when we get more we shall share more.”
The storm that ripped through southeastern Louisiana on Sunday left a still-untold number of people without homes and wreaked havoc on other essential services. Hundreds of thousands of people found themselves in places where water infrastructure was badly damaged by the storm and pumps and treatment plants were left without power.
President Biden, who is expected to visit the state on Friday, said the flash floods that inundated New York City and the powerful winds that knocked out power in Louisiana were a sign that “extreme storms and the climate crisis are here” and that the storms and fires creating life-or-death situations across the country constituted “one of the great challenges of our time.”
“Hurricane Ida didn’t care if you were a Democrat or Republican, rural or urban,” Mr. Biden said Thursday, urging Congress to pass his economic agenda when it returned from its recess later this month, in order to provide critical investments in electrical infrastructure. “This destruction is everywhere. And it’s a matter of life and death, and we’re all in this together.”
In the New Orleans area, carbon monoxide poisoning, from the misuse of generators, has sent at least a dozen people to hospitals and was linked to two deaths, the authorities said.
In Jefferson Parish, more populous than the city of New Orleans and right next door, virtually all residents were either experiencing water outages or under advisories to boil their water. Even as the heat was suffocating and air-conditioning almost nonexistent, drinking water in most of the parish was limited to whatever one had stocked before the storm or could get after waiting in lines for hours.
“This has become basic-level subsistence,” said Steve Robinson, the senior pastor of Church of the King, which has a site in Kenner, where a line of cars rolled through as volunteers from his congregation handed out pallets of water and buckets packed with toiletries, flashlights, first-aid kits and nonperishable foods. They eventually ran out of warm meals.
