El Niño is officially with us, and it’s looking like it’s likely going to be a doozy.
The natural global climate pattern temporarily warms the eastern tropical Pacific, causing extreme weather patterns across the globe. A strong El Niño has historically, though not always, been associated with very wet winters here in Southern California.
“ We are now explicitly expecting the strongest El Niño event ever observed,” said University of California climate scientist Daniel Swain. “ There will be a strong tilt in the odds towards wet, perhaps even very wet conditions in Southern California.”
Maybe you remember the very wet El Niños of years past — 1982 and 1997. Both were historic events that led to billions of dollars in damage and dozens of deaths. Though not a guarantee of a wet winter here, Swain says, this time, the ocean is likely to get even warmer than it was during those years.
“This is highly likely to exceed what occurred in [1982 or 1997], and by a considerable margin,” Swain said.
The good news? You still have time to prepare.
Experts emphasize that people need to develop an understanding of their personal risk, talk to neighbors who may have experienced flooding in the past and consider getting insured.
What you need to know about El Niño
El Niño years can be associated with lots of rain in Southern California, though there's no guarantee of a deluge.
And wet winters aren’t always disastrous. What matters is how much water falls within how much time. In fact, going back to when modern records began in 1950, most of the years when we've seen the highest flood-related costs were not during El Niño events.
But there are concerns beyond rain for late 2026 and early 2027.
El Niño this time will coincide with another natural phenomenon — the highest tides of the year in a nearly two-decade cycle known as “the declination of the moon.” We’re reaching the max this winter, according to Scripps scientist Mark Merrifield.
Because El Niño warms the ocean, it also raises sea levels temporarily. On top of that there’s an unprecedented level of human-caused global warming in the mix — that has already raised sea levels by as much as a foot along California’s coast over the last century, and is making normal weather patterns more extreme.
“So we start adding these things up, and they're actually not so small anymore,” said climate scientist Daniel Swain. “The risk of coastal flooding is actually very high and almost guaranteed.”
It’s not only the coast — inland areas, especially along creeks and rivers, are also at risk due to more extreme rainfall driven by El Niño as well as human-caused global heating, Swain and other experts said.
Know your risk
The Federal Emergency Management Agency, or FEMA, compiles flood risk maps (you can also use this L.A. County map here).
Be aware that they are not comprehensive and can be out-of-date. Also, they include only risk from coastal flooding, such as tides and waves, as well as from rivers, creeks, channels and levies, which risk spilling over after back-to-back severe storms.
But the maps don’t include flood risk from short, heavy downpours or mudflows in recent burn zones, said Brett Sanders, a professor leading UC Irvine’s Flood Lab. So even if your home is not within an official flood zone, you could be at risk.
Visit L.A. County's rain preparation website or call 1-800-933-0930 to speak with a county expert about flood risk in your specific area.
Listen to this conversation from AirTalk's Larry Mantle with Director of L.A. County Public Works Department and UCLA professor Alex Hall about what we can expect from and how to prepare for this year's El Niño.
“What used to be grasslands and open space has been covered more and more by asphalt and concrete,” Sanders said. “And so more and more water runs off and these flood risks are increasing.”

His lab has been working to figure out how to develop more comprehensive flood maps, to better determine risks and reflect changes brought on by a warming climate.
But Sanders said one of your best bets to prepare is low-tech: speak with neighbors or officials who know your local area, and remember how past severe rain events have affected your street or neighborhood. For example, if you live at the base of a hill, or in a basement or ground-level apartment, you’re more likely to see some water flow. That historical memory can help you develop a plan for a worst-case scenario.
“Some common sense local awareness from people is really valuable,” Sanders said. “Talk to somebody that's been around for a while. Ask them, ‘Do you remember floods happening here in the past?’ Or, ‘What happened in 1997 when we had our last really wet El Nino?’”
Once you know, consider filling sand bags ahead of time, keep drainages around and on your house clear, and think about how flooding may affect your travel routes.
People who live in recent wildfire burn areas are likely through the worst of it, Swain said.
“ I think the initial highest risk period will have passed by this winter,” he said.
Still, mudflow is possible. So remember how mud flowed during the storms soon after the 2025 L.A. fires and make sure you have what you need to protect your property and evacuate safely if needed.
Consider flood insurance
Homeowners and renters should take a moment to read their current insurance policies closely. Most homeowners insurance, as well as renters insurance, does not include coverage for flooding (water damage coverage is not flood coverage). Less than 2% of Californians have flood insurance at all.
If you don’t have it, get a quote, said Amy Bach, director of United Policyholders, a nonprofit that advocates for insurance consumers. Flood insurance is usually a lot cheaper than typical insurance.
“ Don't make a decision not to carry flood insurance without getting a quote,” she said. “Find out how much it would cost before you decide.”
If you do get flood insurance, it’ll take about a month to kick in, so you want to start looking now before the official start of the wet season in October.
How LAPD responds when someone is experiencing a mental or behavioral health crisis is getting a closer look. Last week, Mayor Karen Bass issued an executive directive ordering an independent review of the department’s response, including its policies, training and use of force.
Why it matters: LAPD officers fatally shot more than 60 people between 2021 and 2025, according to the most recent data the department reported to the California Department of Justice. All of those deaths will be reviewed.
Why now: “There is a severe shortage of mental and behavioral health care, and too many people in crisis have nowhere to turn,” Mayor Bass said in a prepared statement. “People cycle between the streets, emergency rooms, and detention facilities, and too often come into contact with law enforcement.”
What's next: The Los Angeles Board of Police Commissioners will need to retain an independent firm to conduct the audit and report back recommendations to the mayor’s office within six months. Bass said that the firm selected should be experts in constitutional policing and crisis response.

“There is a severe shortage of mental and behavioral health care, and too many people in crisis have nowhere to turn,” Mayor Bass said in a prepared statement. “People cycle between the streets, emergency rooms, and detention facilities, and too often come into contact with law enforcement.”
The Los Angeles Board of Police Commissioners will need to retain an independent firm to conduct the audit and report back recommendations to the mayor’s office within six months. Bass said that the firm selected should be experts in constitutional policing and crisis response.
The review will determine how officers identify people in crisis, including those with intellectual and physical disabilities, and people who are under the influence of illicit substances.
LAPD officers fatally shot more than 60 people between 2021 and 2025, according to the most recent data the department reported to the California Department of Justice. All of those deaths will be reviewed.
The audit will also look into how the department tracks repeat calls about a person who is in crisis or needs help. Yong Yang’s case is one example. Yang was fatally shot by police in 2024, after his parents attempted to get him help during a behavioral health crisis.
His parents previously told The LA Local about how Yong Yang had nonviolent encounters with police before the encounter that ended in his death. They question why officers failed to de-escalate the confrontation before he was shot.
They’ve continued to call for accountability, even after LAPD closed its investigation into his death. Under Bass’ new directive, his case is one that would be reviewed.
The audit will evaluate:
Use of force: Incidents over the last five years of uses of force and arrests that resulted in death or serious bodily injury to determine if the person was experiencing a behavioral health crisis or had an intellectual disability.
De-escalation: Incidents over the last five years that did not result in death or serious bodily injury to determine how they were de-escalated.
Repeat calls: The department’s procedures for keeping track of people involved in repeated calls to police, including those who have a disability.
Training: The training officers receive about incidents with people experiencing behavioral crises.
Less-lethal options: What less-lethal force options are available to officers.
Custody and care: Uses of restraint and processes for medical treatment for people in police custody.
Officer wellness: Protocols for providing officers with mental health care after these confrontations.
Bass’ order comes about a month after the police department released graphic videos of men who died during police encounters. One video captured officers sitting on and restraining a handcuffed man for an extended period of time at a holding facility in the San Fernando Valley. The man, Jose Carlos Hoyos-Munoz, died soon after.
“When an encounter results in death or serious injury, we must rigorously examine whether our policies, training, tactics, supervision, and accountability systems are sufficient,” Bass said after the videos were released.

Topline:
The California State Auditor says L.A. County Public Health’s response to the health conditions around the Chiquita Canyon landfill was inadequate.
The backstory: An underground chemical reaction at Chiquita Canyon landfill has burned for years, producing large amounts of noxious chemicals and bad odors. Residents nearby have complained about symptoms like headaches and nausea.
What’s new: The State Auditor released a report this week that found the county’s public health department hasn’t done enough to help or inform the community. For example, the audit says the department got reports from the landfill operator every quarter at times showing chemical levels that exceeded state thresholds, but didn’t let the public know. The department in its response said it considers a number of factors on deciding what poses a potential health risk.
More about LADPH response: The department said the report lacked context as to the department’s role within a multi-agency response and said it has been proactive to community health concerns. “It is therefore disappointing that the focus of the audit largely evaluates Public Health’s actions in isolation and not as part of a response structure created by federal, state, and local agencies,” a spokesperson told LAist in a statement.

A new law will require local agencies to publicly disclose audio recordings and written records of 911 calls originating from privately run immigration detention facilities.
The Detention Facility Transparency Act: Gov. Gavin Newsom signed Senate Bill 423, called the Detention Facility Transparency Act, on Tuesday. It was one of 21 immigration-related bills in a package his office announced the same day. The law will require local agencies to turn over recordings and written records of 911 calls from privately run detention facilities if a member of the public requests them. It includes an exception if an active investigation is underway and requires redacting the names of affected individuals.
The backstory: In February, L.A. Taco reported that detainees inside Otay Mesa were throwing lotion bottles wrapped with notes about conditions inside over the wall of the facility to organizers standing outside. Earlier this year, CalMatters sought information, including 911 audio records and other reports, about alleged serious incidents at detention facilities through a California Public Records Act request. While a San Diego County sheriff’s spokesperson said the agency was not investigating those cases, he said he was unable to turn over additional records because they were part of “a law enforcement investigation.”
A new law will require local agencies to publicly disclose audio recordings and written records of 911 calls originating from privately run immigration detention facilities. The bill was prompted by CalMatters reporting on alleged sexual assaults at the Otay Mesa Detention Center.

“Well, it goes without saying, these past two years, Donald Trump has brought fear and has brought anxiety, disruption and stress to our immigrant communities,” Newsom said in a recorded video statement on his website.
“So, today, I sign a number of bills to strengthen transparency and to strengthen accountability and oversight over federal immigration enforcement and civil detention in our state,” the governor said.
State Sen. Lena Gonzalez, a Democrat from Long Beach, introduced SB 423 as state investigations and courts found serious gaps in essential medical care within the facilities. She said the aim was to stop private operators, and the agencies that work alongside them, from keeping what happens behind detention walls from the public's view.
In February, L.A. Taco reported that detainees inside Otay Mesa were throwing lotion bottles wrapped with notes about conditions inside over the wall of the facility to organizers standing outside.
“For 280 days we haven’t eaten a single piece of fruit, banana, apple, orange, or anything fresh," an Otay Mesa detainee wrote, the news outlet reported. "We are all in one big room with no doors or windows. We can’t see any grass or trees. We are all constantly sick.”
Gonzalez, who is chair of the Legislative Latino Caucus, said no person “should have to resort to throwing notes over the walls of a detention facility to have their needs met and their voices heard.”
Earlier this year, CalMatters sought information, including 911 audio records and other reports, about alleged serious incidents at detention facilities through a California Public Records Act request. While a San Diego County sheriff’s spokesperson said the agency was not investigating those cases, he said he was unable to turn over additional records because they were part of “a law enforcement investigation.”
“When journalists and reporters attempted to obtain records about reported incidents at these facilities through the Public Records Act, they faced severe pushback from law enforcement, citing vague investigatory records exemptions, despite there being no active investigation,” said Gonzalez.
Immigrant Defense Advocates and the First Amendment Coalition co-sponsored the bill.
“The governor has sent a powerful message: No more secrecy. SB 423 makes clear that 911 calls and related records about events in detention must be released upon request. This will shed more light on a notoriously opaque system, leading to stronger oversight and accountability,” Ginny LaRoe, Advocacy Director, First Amendment Coalition, said in a written statement.
Gonzalez’s bill was one of several detention oversight bills Newsom signed Tuesday. Others impose a new 25% tax on private detention facilities, expand health, safety and oversight requirements for the centers, and add to the state attorney general’s oversight role.
Why now: The ride has been closed since the evening of July 12, after two women who rode the coaster less than a week apart both needed to be rushed to the hospital after they exited. One of them, 25-year-old Naomi Greer-Wilkinson, collapsed shortly after the ride ended and was found to have massive brain bleeding inside the skull that required emergency brain surgery. She remains in a vegetative state in the hospital, unable to speak or move and dependent on a ventilator. Her family filed a lawsuit against Six Flags on her behalf.
Why it matters: Six Flags recently settled a wrongful-death lawsuit from the family of a 22-year-old man who died after riding the coaster in 2022, and three more lawsuits alleging traumatic brain injuries were filed last week. “While X2 consistently passed a multitude of safety tests, we have decided to close the ride because we believe it’s the right thing to do,” park President Brian Oerding said in an online announcement. “Ride safety is a cornerstone of our business, and when we see guest confidence affected, we take it seriously.”
The backstory: According to the Six Flags Magic Mountain website, the X2 roller coaster reaches a top speed of 76 mph (122 kph) and has a total length of 3,610 feet (1,100 meters). The seats rotate 360 degrees “so your body will be flipping around the entire time,” and the ride features two “raven turns” — half loops that turn into sheer drops midway. It debuted at the park in 2002 under the name X as the world’s first “fourth-dimension” roller coaster and reopened in 2008 as X2 with new trains and special effects. The uniqueness of the ride drew thrill-seekers from around the world and garnered a fervent fanbase.
The Southern California theme park said Tuesday that it is permanently shuttering the ride after nearly 20 years. Six Flags recently settled a wrongful-death lawsuit from the family of a 22-year-old man who died after riding the coaster in 2022, and three more lawsuits alleging traumatic brain injuries were filed last week.
“While X2 consistently passed a multitude of safety tests, we have decided to close the ride because we believe it’s the right thing to do,” park President Brian Oerding said in an online announcement. “Ride safety is a cornerstone of our business, and when we see guest confidence affected, we take it seriously.”

She remains in a vegetative state in the hospital, unable to speak or move and dependent on a ventilator. Her family filed a lawsuit against Six Flags on her behalf.
Her attorneys said more than 100 people claimed they suffered brain injuries from the roller coaster in the past two years, and more lawsuits would be filed in the coming weeks.

The park settled a wrongful-death lawsuit filed by the family of Christopher Hawley, a 22-year-old who died the day after he rode X2. He was taken to the hospital after the ride with severe brain bleeding. The medical examiner’s office said his death was from blunt head trauma. The case was settled at the end of August, a few days before the trial was scheduled to start.
