Hurricane Ida, the rapidly intensifying storm barreling toward Louisiana, could be one of the most powerful to hit the state in more than a century, meteorologists and state officials warned on Saturday.
“We can sum it up by saying this will be one of the strongest hurricanes to hit anywhere in Louisiana since at least the 1850s,” said Gov. John Bel Edwards at a news conference, warning residents that their window to evacuate the area was closing.
Ida, which passed through the Cayman Islands as a tropical storm and made landfall in Cuba on Friday as a Category 1 hurricane, is causing mass evacuations in Louisiana as meteorologists expect the Category 2 hurricane to strengthen into a Category 4 storm when it makes landfall on Sunday afternoon or evening.
The hurricane could batter Louisiana with maximum sustained winds of 130 miles per hour on Sunday, the 16th anniversary of Hurricane Katrina.
“It’s very painful to think about another powerful storm like Hurricane Ida making landfall on that anniversary,” Mr. Edwards said. “But I also want you to know that we’re not the same state that we were 16 years ago.”
The government has invested billions of dollars in improving the region’s storm protection infrastructure. Ida will present a significant test of that system.
On Saturday, a hurricane warning was in effect from Intracoastal City, La., to the mouth of the Pearl River, a region that includes New Orleans. Coastal counties or those near the Gulf of Mexico in Mississippi and Alabama were also warning their residents of likely hurricane damage.
Kevin Gilmore, a meteorologist with the National Weather Service in New Orleans, said the hurricane will have “life-threatening impacts.”
“We’re not saying, ‘possible,’ — we’re saying, ‘will occur’ because we want people to take this extremely seriously,” Mr. Gilmore said. “I cannot stress enough how significant of a situation this is.”
Louisiana was also battered by several storms last year, including Hurricanes Laura and Delta.
Storm surge warnings were issued as well. The National Hurricane Center said that, depending on the tides, the surge could be as high as 15 feet in Morgan City, La., and reach up to 7 feet in Lake Pontchartrain. A storm surge warning was also issued for the coastal areas in east Alabama and Florida.
Total rainfall accumulation could reach as high as 20 inches in southeast Louisiana, with flash flooding, catastrophic wind damage and life-threatening storm surge also likely, the center said.
“Preparations to protect life and property should be rushed to completion today in the warning area along the northern Gulf Coast,” the center said.
By Saturday evening, Ida had maximum sustained winds of 105 miles per hour, making it a Category 2 hurricane, and additional strengthening was expected throughout the day, the National Hurricane Center said.
“The strengthening process is definitely in full swing,” said Dennis Feltgen, communications officer with the National Hurricane Center.
The crucial question, for residents and emergency authorities along the Gulf Coast, is how much stronger it will become before making landfall in the United States.
The hurricane center said the storm could grow much stronger very rapidly, becoming a major hurricane — defined as Category 3 or higher, with maximum sustained winds of at least 111 m.p.h. — in the 24 hours before landfall.
Mr. Edwards declared a state of emergency on Thursday, and Gov. Kay Ivey of Alabama issued a state of emergency for the state’s coastal and western counties on Saturday, saying local officials expected “the possibility of flooding and even spinoff tornadoes in portions of Alabama.” In Mississippi, Gov. Tate Reeves also issued a state of emergency on Saturday, allowing for the use of state resources for response and recovery.
Research over the past decade has found that, on average, such rapid intensification of hurricanes is increasing, in part because the oceans, which provide the energy for hurricanes, are getting warmer as a result of human-caused emissions of greenhouse gases. But Ida will also strengthen quickly because the Gulf, as is usual at the end of the summer, is very warm.
The hurricane center defines rapid intensification as at least a 35-m.p.h. increase in sustained winds over 24 hours. In the extremely active 2020 season, Hurricane Laura intensified by 45 m.p.h. in the 24 hours before making landfall in Louisiana as a Category 4 storm in late August.
The National Hurricane Center said Ida was likely to produce heavy rainfall late Sunday into Monday from southeast Louisiana to coastal Mississippi and Alabama. Tropical storm force winds will arrive along the coast as early as Saturday night, according to the National Weather Service, before the storm makes landfall on Sunday afternoon or evening. After moving inland, the storm could contribute to flooding in Tennessee, where flash flooding killed 20 people last weekend.
“Based upon current track and strength of Ida, this storm will test our hurricane protection systems in a way they haven’t been tested before,” Chip Kline, executive assistant to the governor of Louisiana for coastal activities, said on Twitter. “It’s times like these that remind us of the importance of continuing to protect south Louisiana.”
Because of an editing error, an earlier version of this article misidentified the location of Tropical Storm Ida. It was in the Caribbean Sea early Friday, not the Gulf of Mexico.
Hurricane Ida will produce “life-threatening” weather conditions in Louisiana and batter parts of Mississippi, the National Weather Service said, urging people to evacuate inland.
Here is a breakdown of how various parts of the region could be affected when the hurricane makes landfall on Sunday afternoon or evening , according to the Weather Service.
Residents in the metro area can expect winds of 110 m.p.h. and, potentially, more than 20 inches of rain.
Inundation could reach as high as 11 feet. Residents can also expect winds of 74 m.p.h. and up to 12 inches of rain.
Tornadoes are possible in all of these areas, the Weather Service said.
Hurricane Ida is expected to make landfall Sunday, threatening to bring dangerous wind, storm surge and rain to the Gulf Coast exactly 16 years after the arrival of Hurricane Katrina, one of the most costly natural disasters in American history, which left more than 1,800 dead and produced more than $100 billion in damages.
The overall impact of storm surge from Ida is predicted to be less severe than during Katrina. Because that storm began as a Category 5 hurricane in the Gulf of Mexico before weakening as it approached landfall, it generated enormous storm surge, which brought over 20 feet of water to parts of the Mississippi coast. Current projections put the storm surge of Ida at 10 to 15 feet.
“Fifteen-foot sure can do a lot of damage,” said Barry Keim, a professor at Louisiana State University and Louisiana State Climatologist. “But it’s going to be nothing in comparison with Katrina’s surge.”
Improvements to the levee system following Katrina have better prepared the New Orleans metro area for the storm surge.
However, the areas likely to receive the most severe surge from Ida may be less equipped to handle it than the area hit by Katrina, said Dr. Keim.
Ida is expected to make landfall to the west of where Katrina struck, bringing the most severe storm surge impacts to the Louisiana coast west of the Mississippi River rather than east of the river along coastal Mississippi, as Katrina did.
“We are testing a different part of the flood protection in and around southeast Louisiana than we did in Katrina,” said Dr. Keim. “Some of the weak links in this area maybe haven’t been quite as exposed.”
While the impacts of Ida’s storm surge are expected to be less severe than Katrina’s, Ida’s winds and rain are predicted to exceed those that pummeled the Gulf Coast in 2005.
Ida is expected to make landfall on the Gulf Coast as a Category 4 storm with peak winds of 130 mph, while Katrina made landfall as a Category 3 with peak winds of 125 mph.
“It could be quite devastating — especially some of those high rise buildings are just not rated to sustain that wind load,” said Jamie Rhome, acting deputy director of the National Hurricane Center.
The severe damage from Hurricane Laura, which struck southwest Louisiana last year as a Category 4 storm, was caused primarily by high winds peaking at 150 mph. The storm caused 42 deaths and damage costing more than $19 billion.
Ida’s rainfall also threatens to exceed Katrina’s highs.
The National Hurricane Center estimates that Ida will drench the Gulf Coast with 8 to 16 inches of rain and perhaps as much as 20 inches in some places. Katrina brought 5-10 inches of rain with more than 12 inches in the most impacted areas.
“That is a lot of rainfall,” said Mr. Rhome. “Absolutely the flash flood potential in this case is high, very high.” Especially combined with storm surge, he said, such intense levels of rainfall could have a “huge and devastating impact to those local communities.”
NEW ORLEANS — When a hurricane comes roaring toward New Orleans out of the Gulf of Mexico, there is a discernible mood shift on Bourbon Street, the city’s famed strip of iniquity and conspicuous alcohol consumption.
It goes from tawdry to tawdry with a hint of apocalypse. On Friday afternoon, the street was half alive. Daiquiri bars were open and daiquiri bars were boarded up. The doors to Larry Flynt’s Hustler Club were locked. Nearby, a man lay on his back on the sidewalk, a plastic bag at his side, yelling the name “Laura.” Or maybe “Lord.”
Six happy women from New York ambled toward Canal Street in matching black T-shirts that said, “Birthday, beignets and booze.” The birthday girl declined to give her name. They went past the club called The Famous Door, where a listless bar band played “Fat Bottomed Girls.”
The riffs poured out into the street. A member of the birthday team raised a glass of something alcoholic and sugary and shouted out the chorus.
Another of the New York women, Jessika Edouard of Long Island, said that most of her group had been trying to get out of town before the storm’s arrival, to no avail. It was all cancellations and unresponsive airline customer service. “The flights are terrible,” she said.
What choice did they have but to keep the party going? Ms Edouard thought she and some of the others might be able to leave on Monday, after Ida hit.
In the meantime, she said, they had bought a ton of booze in the French Quarter. In the morning they had beignets. They had just met a crew from the Weather Channel. They seemed more excited than scared.
Ms. Edouard even had words for the storm, which she delivered like a threat from one pro wrestler to another.
“If Hurricane Ida thinks she is going to ruin my friend’s 30th birthday, then Ida has another thing coming,” she said.
NEW ORLEANS — With Hurricane Ida likely to bring powerful winds and heavy rain to their city, residents of New Orleans faced a familiar choice: flee or hunker down for the duration.
The storm was expected to make landfall by Sunday afternoon or evening and officials urged people who intended to evacuate to do so by Saturday. Residents came to a variety of decisions on the matter.
Lacy Duhe, 39, and Jeremy Housely, 42, opted to hunker down in their second-story apartment on Deslonde Street in New Orlean’s Lower Ninth Ward. If they evacuated and ended up in a shelter, they said, they worried about the risk of their unvaccinated children contracting Covid-19. They also had just paid their monthly bills and could not afford to go anywhere.
“It feels serious,” said the couple’s 11-year-old daughter, Ja-nyi. “I wasn’t born during Katrina time. But I know it knocked down a lot of places.”
Mary Picot, 71, walked out the door on Saturday afternoon carrying bags of snacks and medicine. She wasn’t worried about flooding and believed the levees would hold. It was the threat of power outages that convinced her to leave.
“My husband is diabetic,” she said. “We have to keep his medicine cold.”
Donald Lyons, 38, was packing up a silver Nissan sedan Saturday afternoon under a cloud-filled sky in Hollygrove, one of the traditionally Black working class neighborhoods that flooded badly when Katrina hit. The car, carrying his wife, three children and mother-in-law, was full of bags and bedding. They were heading to Sugar Land, Texas, 27 miles southwest of Houston, where they had family that had left after Katrina, 16 years ago, and never come back.
“I’m just trying to get somewhere safe,” Mr. Lyons said.
Down the block, Barbara Butler, 65, a housekeeper, said she thought the city was safer now with all of the new flood protection. She intended to ride out the storm at home.
“It gave us some relief,” she said. “It’s better than no relief.”
She was sitting on the porch with her husband, Curtis Duck, 63, and her brother, Ray Thomas, in a house that Ms. Butler said was flooded with eight feet of water after Katrina.
Mr. Duck said he was sick of evacuating time and again.
“We listen to the news,” he said. “People telling us to go, go, go.”
Victor Pizarro, a health advocate, and his husband decided to ride out the storm in their home in the Gentilly Terrace neighborhood, although they said they would leave town if they lost power for an extended period.
“It’s definitely triggering to even have to think about this and make these decisions,” Mr. Pizarro said in a telephone interview while he drove across town in search of a spare part for his generator. “It’s exhausting to be a New Orleanian and a Louisianian at this point.”
Andy Horowitz and his family decided to vacate their home in the Algiers Point neighborhood, which sits directly across the Mississippi River from the French Quarter. Mr. Horowitz is the author of “Katrina: A History, 1915-2015,” and he is among those scholars and Louisiana residents who fear that the city’s new flood protection system, as massive as it is, may prove to be inadequate for a sinking city in the likely path of more frequent and powerful storms in the age of climate change.
“Every summer, New Orleans plays a game of Russian roulette, and every summer we pull the trigger,” Mr. Horowitz said.
NEW ORLEANS — With tracking maps for Hurricane Ida consistently showing an expected pathway toward southeast Louisiana, Mayor LaToya Cantrell of New Orleans issued a stern warning on Saturday that city residents who intend to leave should do so immediately.
“In no way will this storm be weakening, and there’s always an opportunity for the storm to strengthen,” Ms. Cantrell said at a news briefing. “Time is not on our side. It’s rapidly growing, it’s intensifying.”
City officials are asking that residents who plan to stay in the city prepare for extended power outages, limited emergency services and several days of high temperatures after the storm passes.
“The first 72 is on you,” said Collin Arnold, director of the New Orleans Office of Homeland Security and Emergency Preparedness. “The first three days of this will be difficult for responders to get to you.”
Forecasters are predicting that Hurricane Ida will be a Category 4 storm upon landfall on Sunday, the 16th anniversary of Hurricane Katrina, which left more than 1,800 dead.
“What we learned during Hurricane Katrina is we are all first-responders,” Ms. Cantrell said. “It’s about taking care of one another.”
NEW ORLEANS — On Saturday afternoon, the Rev. Willie L. Calhoun Jr., a 71-year-old resident of the Lower Ninth Ward, was in his Lincoln Continental on the brink of getting out of town. He was not quite sure where. Somewhere in Alabama, he figured.
Rev. Calhoun remembers his father smashing a hole in the roof of his family’s home in the Lower Ninth in 1965, when Hurricane Betsy put 10 feet of water in his house. When Katrina came, he and his family made sure to get out of the neighborhood before the storm destroyed their homes — unlike many of his neighbors, some of whom perished when the levees failed.
The pain from Katrina was now an indelible fact of life in the neighborhood. He had hoped to take part in a 16th anniversary commemoration on Sunday, with a high school marching band and a theme, he said, of “healing, unifying and strengthening our communities.”
“The trauma, and the hurt that’s there,” he said. “I have one friend who lost his mother and his granddaughter in Katrina. For that trauma to be revisited every year is a tough thing.”
But his perspective on the neighborhood 16 years on was somewhat nuanced. He felt confident that the improvements to the city’s storm protection system — with its mammoth flood walls and new gates and levees — would keep the Ninth Ward safe. His worry, he said, was the damage from the wind that comes with a Category 4 hurricane.
And yet it was difficult not to be disappointed. The jobs for Black men seemed to have dried up in the city. A revamped post-Katrina educational system, heavily reliant on charter schools, did not seem, in Rev. Calhoun’s opinion, to have done much good. The neighborhood was in need of economic stimulus. Still full of empty lots, and ghostly foundations of homes, many of them owned by Black families, long washed away.
After $20 billion in infrastructure improvements, it felt, at best, like partial progress, and like survival with an asterisk.
LAKE CHARLES, La. — Not again. That was the widespread sentiment among residents of Lake Charles, a city of about 76,000 residents some 200 miles from New Orleans, on Saturday.
A year after Hurricane Laura left many here without power — and some without homes — for long periods of time, residents were preparing for perhaps yet another weather catastrophe.
When Laura, a powerful Category 4 storm, barreled through Lake Charles last August, it shattered the windows of the home that Juan Jose Galdames, 55, a construction worker, shared with his five children. On Saturday, he was at Home Depot, buying plywood to protect the windows and other vulnerable parts of his house ahead of the storm.
“Yes, I am a little afraid,” Mr. Galdames said. “I don’t want a repeat of that day. It was scary. I want my children to feel safe. I’m trying to get everything ready before nightfall.”
Water and bread were in short supply at an area Target store, and traffic stretched for miles as residents sought safety elsewhere.
Tracy Guillory, 57, a carpenter, tried to prepare by stocking up on supplies and staying on top of weather reports. She said she and her family were weary after a long year of weather crises that included Hurricane Delta and a winter storm that caused pipes to burst and knocked out water systems throughout the region.
Ms. Guillory said her neighborhood was still recovering from flooding in May, which left her SUV beyond repair. She plans to hunker down with her 83-year-old father and 21-year-old daughter.
Josue Espinal, 34, who also works in construction, was trying to reassure his 4-year-old son, Anderson, that everything would be all right. The boy sat on top of a generator box as his father loaded a cart with bottles of water at a Home Depot. Truth was, Mr. Espinal admitted, he too was worried. He and his family live in a mobile home near a lake, and he was looking for a better option to spend the next two nights.
In Louisiana, where daily deaths from Covid reached their highest levels this week, stretched hospitals are having to modify the intense preparations they would normally make ahead of an expected strike from Hurricane Ida.
Louisiana’s medical director, Dr. Joseph Kanter, asked residents on Friday to avoid unnecessary emergency room visits to preserve the state’s hospital capacity, which has been vastly diminished by its most severe Covid surge of the pandemic.
And while plans exist to transfer patients away from coastal areas to inland hospitals ahead of a hurricane, this time “evacuations are just not possible,” Gov. John Bel Edwards said at a news conference.
“The hospitals don’t have room,” he said. “We don’t have any place to bring those patients — not in state, not out of state.”
The governor said officials had asked hospitals to check generators and stockpile more water, oxygen and personal protective supplies than usual for a storm. The implications of a strike from a Category 4 hurricane while hospitals were full were “beyond what our normal plans are,” he added.
Mr. Edwards said he had told President Biden and Deanne Criswell, the administrator of the Federal Emergency Management Agency, to expect Covid-related emergency requests, including oxygen.
The state’s recent wave of Covid hospitalizations has exceeded its previous three peaks, and staffing shortages have necessitated support from federal and military medical teams. On Friday, 2,684 Covid patients were hospitalized in the state. This week Louisiana reported its highest ever single-day death toll from Covid — 139 people.
Oschner Health, one of the largest local medical systems, informed the state that it had limited capacity to accept storm-related transfers, especially from nursing homes, the group’s chief executive, Warner L. Thomas, said. Many of Oschner’s hospitals, which were caring for 836 Covid patients on Friday, had invested in backup power and water systems to reduce the need to evacuate, he said.
The pandemic also complicated efforts to discharge more patients than usual before the storm hits. For many Covid patients who require oxygen, “going home isn’t really an option,” said Stephanie Manson, chief operating officer of Our Lady of the Lake Regional Medical Center in Baton Rouge, which had 190 Covid inpatients on Friday, 79 of them in intensive care units.
The governor said he feared that the movement of tens or hundreds of thousands of evacuees in the state could cause it to lose gains made in recent days as the number of new coronavirus cases began to drop. Dr. Kanter urged residents who were on the move to wear masks and observe social distancing. Many of the state’s testing and vaccination sites were slated to close temporarily.
NEW ORLEANS — As Hurricane Ida heads toward a possible Sunday landfall on Louisiana’s coastline, the National Weather Service’s storm surge forecast has local officials warning about the potential for water to overtop some of the levees that protect parts of New Orleans.
Mayor LaToya Cantrell of New Orleans noted at a news briefing on Friday evening that water overtopping the levees “is as it was structured to do.” That reflects the updates to the local system of earthen and reinforced levees that protects much of southeast Louisiana in the years after Hurricane Katrina stretched it to a breaking point.
The system, officials said, was rebuilt to defend against a so-called “100-year-storm,” or a storm that has a 1 percent chance in happening every year, but to remain reinforced up to a 500-year-event. It includes armoring, splash pads — concrete areas designed to keep the ground behind an overtopped wall from being washed away — and pumps with backup generators, officials said.
Heath Jones, an emergency operation manager with the Army Corps of Engineers, said that some levees protecting New Orleans on the western side of the Mississippi River were at risk of overtopping in line with the Weather Service’s forecast calling for between 10 and 15 feet of storm surge. A federal levee database shows sections of levee there as low as 10 feet.
Levees in this part of the state have rarely been challenged since they were shored up in the years after Hurricane Katrina in 2005.
“The previous big tests were (hurricanes) Isaac and Gustav,” said Matt Roe, a public affairs specialist with the Army Corps of Engineers, which occurred in 2012 and 2008, “but it’s important to note that each storm is different.”
Ida’s strength, according to Chip Cline, chairman of the Coastal Protection and Restoration Authority, “will test our hurricane protection system in a way they haven’t been tested before.”
Hurricane Ida threatens to be the first major storm to strike the Gulf Coast during the 2021 season, hitting a region in many ways still grappling with the physical and emotional toll of a punishing run of hurricanes last year.
The Atlantic hurricane season of 2020 was the busiest on record, with 30 named storms, 13 of which reached hurricane strength. There were so many storms that forecasters ran through the alphabet and had to take the rare step of calling storms by Greek letters.
Louisiana was dealt the harshest blow, barraged repeatedly by storms, including Hurricane Laura, which was one of the most powerful to hit the state, trailed six weeks later by Delta, which was weaker than Laura but followed a nearly identical path, inflicting considerable pain on communities still gripped by the devastation from the earlier storm.
The state is still struggling to claw its way back. Gov. John Bel Edwards of Louisiana said the state had $3 billion in unmet recovery needs. In Lake Charles, which was ravaged by direct hits from both hurricanes followed by a deadly winter storm and flooding in May, local officials recently renewed a plea for federal aid as the city has failed to regain its footing; much of it has yet to recover and many residents, unable to find adequate or affordable housing, have fled.
The looming impact of Ida underscores the persisting danger imperiling coastal communities as a changing climate stands to intensify the destructive force of the storms that have always been a seasonal part of life.
President Biden cited the growing danger in May when he announced a significant increase in funding to build and bolster infrastructure in communities most likely to face the wrath of extreme weather.
Hurricane Nora formed in the eastern Pacific on Saturday morning, threatening much of Mexico’s western coastline as the storm strengthens and barrels its way toward Puerto Vallarta, Jalisco and the tip of the Baja California Peninsula, forecasters said.
As of 10 a.m. on Saturday, Nora was about 425 miles from Cabo San Lucas, Mexico, and had maximum sustained winds of 80 miles per hour as it moved north, according to the National Hurricane Center.
A hurricane warning was in effect for parts of western Mexico.
Forecasters said the storm was expected to cause flooding, mudslides and perilous surf along much of Mexico’s central and northern Pacific Coast.
The remnants of the storm are expected to produce heavy rainfall in parts of the southwestern U.S. and central Rockies toward the middle of next week, forecasters said.
A forecast track from the National Hurricane Center showed Nora skirting close to Mexico’s coastline by Sunday morning before moving toward the Gulf of California a day later.
“Some additional strengthening is forecast through tonight if Nora’s center does not make landfall,” the National Hurricane Center said in an update. “Some gradual weakening is expected to begin by Sunday night or Monday, but Nora is forecast to remain as a hurricane through Tuesday.”
Nora is expected to produce rainfall totals of up to 12 inches this weekend along Mexico’s western coast.
It has been a dizzying few weeks for meteorologists who are monitoring Hurricane Ida this weekend after having monitored three named storms that formed in quick succession in the Atlantic, bringing stormy weather, flooding and damaging winds to different parts of the United States and the Caribbean.
The links between hurricanes and climate change are becoming more apparent. A warming planet can expect to see stronger hurricanes over time, and a higher incidence of the most powerful storms — though the overall number of storms could drop because factors like stronger wind shear could keep weaker storms from forming.
Hurricanes are also becoming wetter because of more water vapor in the warmer atmosphere; scientists have suggested that storms like Hurricane Harvey in 2017 produced far more rain than they would have without the human effects on climate. Also, rising sea levels are contributing to higher storm surges — the most destructive element of tropical cyclones.
