Amid the dramatic devastation caused by Hurricane Ida, there was at least one bright light Sunday outside of New Orleans: Parishioners found that electricity had been restored to their church, a small improvement as residents of Louisiana struggle to regain some aspects of normal life.

In Jefferson Parish, the Rev. G. Amaldoss expected to celebrate Mass at St. Joachim Catholic Church in the parking lot, which was dotted with downed limbs. But when he swung open the doors of the church early Sunday, the sanctuary was bathed in light. That made an indoor service possible.

“Divine intervention,” Amaldoss said, pressing his hands together and looking toward the sky.

As Mass began, Amaldoss walked down the aisle of the church in his green robe, with just eight people spread among the pews. Instead, the seats brimmed with boxes of donated toothpaste, shampoo and canned vegetables.

“For all the people whose lives are saved and all the people whose lives are lost, we pray for them,” he said. “Remember the brothers and sisters driven by the wind and the water.”

Through the wall of windows behind the altar, beyond the swamp abutting the church, the floodgates that saved the building could be seen. The Gospel read out was the story of Jesus bringing sight to a blind man, and throughout the tiny church, stories of miracles were repeated.

Wynonia Lazaro gave thanks for newly restored power in her home, where the only casualties of Ida were some downed trees and loosened shingles.

“We are extremely blessed,” she said.

At least 16 deaths were blamed on Hurricane Ida in Louisiana, Mississippi and Alabama. In the Northeast, Ida’s remnants dumped record-breaking rain and killed at least 50 people from Virginia to Connecticut.

Some St. Joachim parishioners suffered total losses of their homes, or devastating damage, and others were barely touched. Gina Caulfield, a 64-year-old retired teacher, has been hopping from relative to relative after her cousin’s trailer, where she’d been living, was left uninhabitable. Still, she bowed her head in prayer, grateful to have survived the storm.

“It’s a comfort to know we have people praying for us,” she said.

Amaldoss said he had no doubt his congregants would rebuild their lives.

“People’s ability to come back is amazing, and that makes me happy,” he said. “That shows the nature of the people and the love of the people.

But many continue to face food, water and gas shortages while battling heat and humidity a week after Ida struck.

Some parishes outside New Orleans were battered for hours by winds of 100 mph (160 kph) or more. Fully restoring electricity to some of these southeastern parishes could take until the end of the month, according to Entergy President and CEO Phillip May.

Ida damaged or destroyed more than 22,000 power poles, more than hurricanes Katrina, Zeta and Delta combined, an impact May called “staggering.” More than 5,200 transformers failed and nearly 26,000 spans of wire — the stretch of transmission wires between poles — were down.

More than 630,000 homes and businesses remained without power Sunday across southeast Louisiana, according to the state Public Service Commission. At the peak, 902,000 customers had lost power.

Louisiana’s 12 storm-related deaths included five nursing home residents evacuated ahead of the hurricane along with hundreds of other seniors to a warehouse in Louisiana, where health officials said conditions became unsafe.

On Saturday evening, State Health Officer Dr. Joseph Kanter ordered the immediate closure of the seven nursing facilities that sent residents to the Tangipahoa Parish warehouse facility.

“The lack of regard for these vulnerable residents’ wellbeing is an affront to human dignity. We have lost trust in these nursing homes to provide adequate care for their residents,” Kanter said.

As recovery efforts continued, state officials were monitoring a system of disturbed weather in Mexico’s Bay of Campeche, which appeared set to move into the central Gulf of Mexico closer to Louisiana.

Louisiana Gov. John Bel Edwards said the state is planning an exercise to assess its emergency response if needed. Predictions so far don’t show the system strengthening into a hurricane, but he said “even if it’s a tropical storm, we’re in no state to receive that much rainfall at this time.”

Tens of thousands of people who fled South Lake Tahoe in the teeth of a wildfire were returning home as crews finally managed to stall the advance of flames scant miles from the resort.

But authorities warned that residents of the scenic forest area on the California-Nevada state line weren’t out of the woods yet, with risks ranging from smoky, foul air to belligerent bears.

Evacuation orders for South Lake Tahoe and other lakeside areas were downgraded to warnings on Sunday afternoon and California Highway Patrol officers began removing roadblocks along State Highway 50 from Nevada to the city limits.

The threat from the Caldor Fire hasn’t entirely vanished but downgrading to a warning meant those who wish could return to their homes in what had been a smoke-choked ghost town instead of a thriving Labor Day getaway location.

“So far it hasn’t been a mad rush of cars,” South Lake Tahoe Fire Chief Clive Savacool said at an evening briefing. “We’re happy to see that people are slowly trickling in, just because the city does need time to get ready.”

Savacool said officials hoped to have the local hospital emergency room open within 24 hours and said paramedics were staffing fire engines for emergency medical care.

However, he said people with health problems might want to consider staying away because of the smoky air.

People who do return should have enough medication and groceries and a full gas tank in order to be self-sufficient, Savacool said.

Law enforcement was still patrolling so “your home will still be safe,” Savacool said.

However, authorities also warned that in the absence of humans, bears had gone to town, spreading trash everywhere that must be picked up.

“The delicate balance between humans and bears has been upset,” and anyone who thinks a bear may have entered their home should call law enforcement, El Dorado County sheriff’s Sgt. Simon Brown said.

The lifting of mandatory evacuation orders for the Tahoe area marked a milestone in the fight against the fire, which erupted on Aug. 14 and spread across nearly 340 square miles (880 square kilometers) of dense national parks and forests, tree-dotted granite cliffs and scattered cabins and hamlets in the northern Sierra Nevada.

At its peak, the fire had burned as much as 1,000 acres an hour and last month virtually razed the small community of Grizzly Flats.

But in recent days the winds had eased and thousands of firefighters took advantage of the better weather to hack, burn and bulldoze fire lines, managing to contain 43% of the perimeter.

Most of the western and southern sides of the fire had been corralled, although some areas still were off-limits.

No homes had been lost on the northeastern side of the fire nearest to the lake, and crews managed to carve more fire line along one edge of a fiery finger.
