While California is unlikely to see Texas-style summer thunderstorms, experts warn that winter storms, especially atmospheric rivers, can still bring dangerous and deadly floods to the region.
Flooding, California-style: Unlike Texas, California’s flood risk peaks during winter, when atmospheric river storms dump heavy rain that can overwhelm waterways and spark local disasters.
Stay alert: Scientists caution that as storms grow wetter with warming temperatures, Californians must stay alert to increasingly unpredictable and severe weather.
A major thunderstorm like the one that produced devastating flash flooding in Texas over the holiday weekend is not likely in most of California, but climate scientists say that if the perfect weather at the right time of year and geography align, serious flooding can still wreak havoc here.
There are several significant differences between the recent deluge in Texas, which has killed more than 100 people, and the type of flooding that happens in California. First, in the Golden State, it’s the cold winter months that bring flooding, often from back-to-back atmospheric river storms. The instability caused by these rainstorms, which douse the region in water, can generate thunderstorms of varying intensity and trigger flooding.
California typically doesn’t experience massive warm summertime storms because of its Mediterranean climate. The disastrous Texas flooding is a reminder that the ferocity of Mother Nature isn’t always predictable. As the climate continues to warm, resulting in wetter storms, Californians living near waterways need to be prepared for more extreme weather events.
When California floods in the winter, there’s always the possibility of a deadly event depending on where a storm makes landfall. For instance, last November, an atmospheric river parked over the North Bay, causing localized flooding, killing two in Santa Rosa.
“The magnitude of the severity of the flooding absolutely could happen in California, and it is the kind of flooding that we are very concerned about,” said Daniel Swain, a UC Agriculture and Natural Resources climate scientist. “But the physical meteorology involved would be very different.”
How weather messaging works
In Texas, the National Weather Service issued multiple warnings, including its highest level of alert for once-in-a-generation flooding, Swain said. However, the timing of some of the alerts — in the middle of the night — and the regularity of the warnings may have caused people to either miss them or not take them seriously.
Jay Lund, professor emeritus of civil and environmental engineering at UC Davis, likened the immediacy of flash floods to earthquakes.

“They happen right away and with almost no warning,” he said. “You have to have an excellent warning system because if it happens in the middle of the night, most people aren’t going to hear it because they’ll be asleep.”
Like in Kerr County in Texas, most California localities don’t use sirens to alert the public about flooding, “because our flooding kind of builds and we can see what is coming in,” state climatologist Michael Anderson said. However, some do, like the Marin County communities of Fairfax, Ross and San Anselmo, which maintain flood horns or sirensthat they sound when flooding is imminent.
California relies heavily on the weather service for messaging about potential flooding from storms.
When it comes to flooding, the weather service issues watches, warnings and advisories. Flash flood warnings also have three different levels, ranging from the base level to catastrophic. Beyond the alerts, the weather service leans on traditional radio broadcasts, local authorities and news outlets to get the word out.
Garcia said the difference between a warning and an advisory is that a warning suggests “there could be trouble,” but an advisory means “the trouble is coming to you.” He recommends that all Bay Area residents sign up for text emergency alerts at alertthebay.org and pay attention to any “action statements” within the message.
“If the action statement says something like get to high ground immediately, that is a cue to take immediate action,” Garcia said. “Whether it’s moving to higher floors, going to the top of a hill, or moving yourself to higher ground.”
Flooding from thunderstorms is possible in California
What distinguishes localized flash flooding events from those in Texas is the duration of the atmospheric river, its geographic location and the level of wetness in the system. Atmospheric rivers in California can last for days and arrive in a succession train, while thunderstorms last for a few hours at most.
“Texas can get these systems that consist of thunderstorms that don’t move very much over a period of time, producing an enormous amount of rainfall,” said John Monteverdi, emeritus professor of meteorology at San Francisco State University. “That’s different from the kind of flooding that happens when the Russian River floods, maybe once every two or three years.”

Still, a big flash-flood-producing thunderstorm in California isn’t entirely out of the picture and can occur during the summertime in the Sierra Nevada or the deserts across the southeastern part of the state.
“The kind of thing that happened in Texas could also happen in California,” said Nicholas Pinter, associate director of the UC Davis Center for Watershed Sciences. “Anyone out hiking in confined, rugged topography needs to be aware that we have this risk of flash flooding in California, kind of similar to Texas.”
While the Texas thunderstorm covering a broad geographic area and producing a wall of water is “not typical of California,” the “wettest precipitation events are getting wetter” and in turn elevating flood risk, which is in line with the effects of human-caused climate change on storms in both states, said Noah Diffenbaugh, a climate scientist at Stanford University.
“We know we’re in a climate where the kind of intense precipitation that leads to flooding is more likely overall for a given storm,” he said. “Our infrastructure in many cases was not designed and built for the most intense conditions that are now occurring.”
California has experienced numerous wet years that resulted in flooding, including the Great Flood of 1862 and other extreme events in 1955, 1964, 1986 and 1997, as well as more recent occurrences such as 2017 and 2023.
For a major flood to occur anywhere in California, a specific set of ingredients — geographic location, soil moisture and storm intensity — is required, according to Anderson, the state climatologist. He pointed to the winter of 2023, when nine atmospheric rivers hit the state over 18 days.
“That’s almost one every other day, and that led to substantial flooding across the state,” he said. “So, what we look for is different than what Texas has to look out for.”

Wildfire-scorched areas are also susceptible to flooding during atmospheric rivers or heavy rains that fall during a monsoon.
“Fire creates a hydrophobic layer on the soil that magnifies the impact of flooding because the water cannot infiltrate it,” said Anna Serra-Llobet, a researcher at the Center for Catastrophic Risk Management at UC Berkeley.
Serra-Llobet said she worries about flooding next winter across wildfire burn scars, especially in Southern California and the Sierra Nevada, as those areas will be primed for flash floods full of ash and debris. In the case of the Los Angeles fires, those floodwaters could hit urban areas.
She said there needs to be more public outreach on how to respond during a flood.
“People don’t understand the risk where they live, and I think we need more drills to be more prepared,” she said. “Creating a risk culture could help many communities to be more proactive and effective in acting during a disaster.”

Following reports of local police assisting federal immigration agents with raids and detentions of citizen observers across Southern California, state lawmakers have introduced a bill seeking to outlaw such collaboration.
The details: State Sen. Sasha Renée Pérez (D-Pasadena) announced Monday that she has introduced SB 1105, dubbed the Protect California Rights Act. The bill would ban local law enforcement from helping federal agents with operations based on racial profiling, efforts to stop First Amendment speech or actions involving unauthorized military weapons.
Why proponents say it’s needed: At a news conference, Pérez said: “Californians deserve to feel safe. They deserve to trust that the officers sworn to protect them will not be used to intimidate them. And they deserve a state government that stands firmly on the side of civil rights and constitutional protections.”
How enforcement would work: The bill is co-sponsored by ACLU California Action. Executive Director David Trujillo said if the bill passes, Californians who’ve been subject to illegal activity by local law enforcement could take their case to court. “The courts will be able to then step in and order local law enforcement to comply with our laws here in California,” Trujillo said.
Community voices: The news conference featured speakers who have been detained by local police in incidents related to federal immigration actions. Jose Madera, director of the Pasadena Community Job Center, said he was arrested last month by Pasadena police while tracking the movements of an alleged ICE agent. “The perception of the community,” Madera said, “is that local police were protecting ICE agents and not protecting us, the residents, legal observers.”
White House position: The Trump Administration and top officials at the Department of Homeland Security have consistently pushed back on efforts to curtail their aggressive enforcement of immigration policies. White House border czar Tom Homan on Sunday, for example, rejected Democrats calls for ICE officers to stop wearing masks, saying that while he didn't "like the masks either" officers said they were needed to protect from doxxing.
Filmmaker Frederick Wiseman has died. The celebrated documentarian started making documentaries that captured the weirdness and wonder of everyday life in the mid 1960s and did not stop until2023.
About his career: The prolific, pioneering filmmaker made dozens of documentaries and chronicled the inner workings of institutions. His 1967 film, Titicut Follies, revealed appalling conditions at a prison facility.
Filmmaker Frederick Wiseman has died. The celebrated documentarian started making documentaries that captured the weirdness and wonder of everyday life in the mid 1960s and did not stop until2023.
Wiseman died Monday. His family issued a joint statement withZipporah Films. He was 96.
Making movies was always an adventure, Wiseman said in 2016, during a speech at the Academy Awards when he won an honorary Oscar.
"I usually know nothing about the subject before I start," he said at the black-tie ceremony. "And I know there are those that feel I know nothing about it when it's finished!"
Wiseman was extremely prolific. He made roughly 50 documentaries, many of which chronicled the inner workings of institutions as diverse as the Idaho state legislature (State Legislature, 2007), the New York Public Library (Ex Libris, 2017), and a high school in Philadelphia (High School, 1968).
"I wish I could be more like him," said Oscar-winning documentarian Errol Morris in an interview with NPR about Wiseman before the elder filmmaker died.
Morris said Wiseman's super-charged yet subtle way of interpreting everyday life had more in common with the Theater of the Absurd than documentary filmmaking. (Indeed, Wiseman also had a career as a theater director in the U.S. and Europe, helming plays by the likes of Samuel Beckett and Luigi Pirandello.)
"He has a way of finding in reality some of the most surreal, absurd moments that I've ever seen anywhere," Morris said.
By way of example, Morris points to a scene in Wiseman's 1993 documentary Zoo, in which an all-women surgical team at Miami zoo castrates a wolf.
"And it seems like the entire scene is populated by women except for the janitor standing by the exit door, looking nervously on with his hands folded over his crotch," Morris said. "To me, this is really almost as good as it gets."
Morris added Wiseman was a mentor to him and a close friend. After Morris lost both his father and brother to heart disease, and was worried about his own fate, the filmmaker said Wiseman organized medical help for him. "I can even credit Fred with saving my life," Morris said.
Frederick Wiseman was born in Boston in 1930. After serving in the U.S. Army during the Korean War and living in Paris during the 1950s, he taught law at Boston University.

It was taking his students on field trips to Bridgewater State Hospital, a Massachusetts prison facility for the criminally insane, that compelled the then law professor to direct his first, and most famous, film. Made in 1967, Titicut Follies gets its title from a stage show put on by the inmates at the institution.
After its seemingly benign opening, the movie captures the appalling conditions under which the inmates are kept, with unblinking scenes of bullying, force feeding, strip searches and squalor.
Titicut Follies was so shocking, the state of Massachusetts managed to get it banned from public screenings for more than two decades.
"In order for anyone to see that film, for years you had to sign a declaration saying that you were a professional in one of the following fields, like criminology, law or film studies," said film scholar Barry Keith Grant, author ofVoyages of Discovery: The Cinema of Frederick Wiseman.
Still, Grant said the movie sealed Wiseman's future.
"It gave him a lot of notoriety and it helped establish his career," Grant said.
Over the years, Wiseman became known for his meticulous, hands-on process. He directed, produced and edited his movies. In a 2014 interview with NPR, the filmmaker described making National Gallery, his documentary about the famed London art museum.
"I was there for three months, every day for twelve weeks, probably twelve, fourteen hours a day," Wiseman said of the shoot, adding he amassed 170 hours of footage. "So the ratio between film shot and film used is about 60 to one."
Wiseman's films were also known for their prodigious length, running for as long as six hours. "I don't tailor the length to meet any commercial needs," Wiseman said. "I assume if people are interested, they'll watch it, whether it's 75 minutes or three hours."

A series of severe weather advisories — ranging from extreme marine conditions to severe thunderstorms and the possibility of hail and water spouts — have peppered Southern California on Monday. The wet start to the week is expected to continue, with concerns about possible mudslides and debris flows in areas hard hit by recent fires.
L.A. Mayor Karen Bass issued an evacuation warning for the Palisades, Sunset and Hurst burn scar areas ahead of the rain Monday. That warning went into effect at 9 p.m. on Sunday and will be in place until 9 a.m. on Tuesday.
Most of L.A. County is under a flood watch as a powerful rainstorm hits the region, that's in effect until midnight Monday. Areas that include much of Central and Southern L.A. County are additionally under a flash flood warning until 2 p.m. Monday. That's due to an observed rainfall rate that's between 0.5 to 0.75 inches in 15 minutes.
Some mountain communities are also under a winter storm warning through Thursday where up to a foot or two of snow is possible for elevations above 6,000 feet.
Forecasters are also warning that it's going to be windy along mountain passes where gusts could reach up to 70 mph Monday afternoon.

We will update as needed.
According to the National Weather Service, locations that will experience flash flooding include Monday afternoon: Long Beach, West Covina, Glendora, San Dimas, Pomona, Whittier, La Verne, Covina, Azusa, Baldwin Park, Diamond Bar, Hacienda Heights, Monrovia, Claremont, Santa Fe Springs, Norwalk, Cerritos, Artesia, Bellflower and Walnut.
Traffic conditions
Rancho Palos Verdes
As of Monday afternoon: Rancho Palos Verdes Drive South is closed in both directions from Wayfarers Chapel to Peppertree Drive due to flooding. Please use an alternate route if you must drive at this time. It is unknown when the road will reopen.
San Fernando Valley
As of Monday afternoon: The 5 Freeway north is closed in Sun Valley from Tuxford Street and Lankershim Boulevard because of flooding.
Orange County
As of Monday afternoon: All lanes Northbound and Southbound at PCH from Seapoint Street to Warner Avenue are closed until further notice.
Meteorologists for the National Weather Service have warned that a powerful storm system will move through the region Monday "bringing the potential for severe thunderstorms, burn-scar debris flows, flash flooding with rock and mud slides, damaging winds, heavy mountain snow, and high surf with coastal flooding."
They say Southern Californians should expect "cold and blustery conditions with periodic rain" through "at least the middle of the week."
The expected rainfall is significant enough that they're warning people near vulnerable areas, which include recent burn scars from last January's fires and other recent fires, to take precautions immediately and be ready to leave if evacuation orders are issued.
Severe weather could include:
Small tornadoes
60 mph or higher winds
Rainfall rates that hit 1 inch per hour or more
Understanding National Weather Service warnings
Here’s an excerpt from our guide to understanding flood warnings, if any are issued:
Flood advisories are how the NWS begins to raise the alarm. The goal is to give people enough time to take action.
Flood watches are your indicators to get prepared to move.
Aflood warning is issued when a hazardous weather event is imminent or already happening. When one is issued for your area, you need to get to higher ground immediately.
A flash flood warning is issued when a flash flood is coming or in progress. Flash floods are sudden and violent floods that can start within minutes.
If you're in L.A. County and need sand bags, you can find some at local fire houses.
Staying safe when the winds are high
Watch for traffic signals that may be out. Approach those intersections as four-way stops.
Make sure you have a battery-operated radio and flashlights. Check the batteries to make sure they are fresh. Use flashlights for lighting during a power outage; do not use candles because they may pose a fire hazard.
If you’re in a vehicle with a fallen power line on it, stay in the vehicle and remain calm until help arrives. It is OK to use your cellphone to call 911. If you must leave the vehicle, exit away from downed power lines and jump from the vehicle, landing with both feet together. You must not touch the vehicle and the ground at the same time. Then proceed away from the vehicle by shuffling and not picking up your feet until you are several yards away.
Water and electricity don’t mix. Water is an excellent conductor of electricity. Do not step in or enter any water that a downed power line may be touching.
Do not use any equipment indoors that is designed for outdoor heating or cooking. Such equipment can emit carbon monoxide and other toxic gases.
If you use a generator, place it outdoors and plug individual appliances directly into it, using a heavy-duty extension cord. Connecting generators directly to household circuits creates “backfeed,” which is dangerous to repair crews.
Leave the doors of your refrigerator and freezer closed to keep food as fresh as possible. Place blocks of ice inside to help keep food cold. Check food carefully for signs of spoilage.
Check on your neighbors to make sure everyone is safe.
Tips on staying warm
State law requires residential units to have heating systems that can keep indoor temperatures at a minimum of 70 degrees. That means every dwelling unit and guest room offered for rent or lease should offer heating equipment.
Use heat smartly to save money: Cranking heaters can be expensive. If money is tight, be judicious about how and when you use your utilities. For example, only use heaters at night or only set the thermostat to around 70 degrees.
Open and close those vents: If you have central A/C, look at where the vents are around your home. Are any open in places where you don’t stay long? Practice opening and closing those so warm air only goes where you need it (most vents should have a small toggle lever). Humidifiers can also help you warm things up — and it’s useful to add moisture into our dry air.
Adjust your wall heaters: If you have a wall heater, you can change the output by adjusting the knob (usually at the bottom). Since wall heaters can only warm the areas where they’re placed, it’s essential to close doors to rooms you won’t be in so hot air doesn’t get wasted.
Turn on your ceiling fan (really): If you have a ceiling fan, try turning it on. This sounds counterintuitive, but there’s science behind it. Since hot air floats up, your fan can help move it around. For warming, your fan should spin clockwise to create an updraft. Not all fans will have this option.

Robert Duvall, who brought a wide range of characters to life, from tough Marines to wistful, tender-hearted cowboys over a long career, has died at 95.
His career: Duvall appeared in over 90 films over the course of his career, imbuing stock Hollywood types — cowboys, cops, soldiers — with a nuanced sense of vulnerability.
What we know about his death: Duvall died on Sunday. His wife Luciana posted on Facebook on Monday, "Yesterday we said goodbye to my beloved husband, cherished friend, and one of the greatest actors of our time. Bob passed away peacefully at home, surrounded by love and comfort."
Over his long career, Robert Duvall brought a wide range of characters to life, from tough Marines to wistful, tender-hearted cowboys.
Duvall died on Sunday. His wife Luciana posted on Facebook on Monday, "Yesterday we said goodbye to my beloved husband, cherished friend, and one of the greatest actors of our time. Bob passed away peacefully at home, surrounded by love and comfort."
He was 95 years old.
In his first major movie role, in 1962, Robert Duvall appeared in only a handful of scenes. He didn't have a single word of dialogue. Yet the actor managed to make an indelible, star-making impression. The film was To Kill a Mockingbird. The role was Boo Radley.
Boo is the small town's recluse; he spends the movie as little more than a mysterious shape, cloaked in shadows. But in the film's final moments, he steps out nervously, into the light.
Duvall's features soften, he smiles slightly — and the menacing presence of Boo Radley transforms before our eyes into a figure radiating kindness and concern. The pure, elegantly nuanced physicality of that moment launched his career.
"I was at a small college in the Midwest," he said. "It was the end of the Korean war. I did go in the army eventually but [only] to get through college, to find something that would give me a sense of worth, where I got my first 'A'. It was my parents I had to thank for that."
As a young actor, he ended up in New York City, where he palled around with Gene Hackman, James Caan and his roommate Dustin Hoffman. It was over many coffees and conversations with them at Cromwell's Drug Store on 50th and 6th Avenue that he struck upon his personal philosophy of acting. His approach was direct and unpretentious, as he explained to the TV series Oprah's Masterclass in 2015: "Basically just talk and listen, and keep it simple. And however it goes, it goes."
After Mockingbird, his parts grew bigger: Films like Bullitt, True Grit, and M*A*S*H, in which he originated the role of the uptight Major Frank Burns.
But it was his role in 1972's The Godfather, as Tom Hagen, the Corleone family lawyer, that changed everything. Amid the film's operatic swirl of emotion, Tom Hagen was an island of calmness and restraint, so it might seem odd that Duvall often said it was one of his favorite roles of his career.
But his strength as an actor was always how unforced he seemed, how true. Others around him emoted, showily and outwardly — he always directed his energy inward, to find a character's heart. This was true even when he played roles with a harder edge.
In two films that came out in 1979 — The Great Santini and Apocalypse Now, both of which earned him Oscar nominations — Duvall played military men. In Santini, he was a bluff, belligerent Marine who bullied his sensitive son in an attempt to harden him into a man.
In Francis Ford Coppola's epically trippy Vietnam War film Apocalypse Now, Duvall was all charismatic swagger as Lieutenant Colonel Kilgore, who calls down an airstrike and delivers one of the most quotable lines in film history: "I love the smell of napalm in the morning. ... It smells like ... victory."
As he told Terry Gross on Fresh Air in 1996, the words followed him for the rest of his life.
"Yeah, that was a wonderful line," he said. "People come up to me and quote it to me like it's this in thing between me and them. Like they're the only ones who ever thought of it, but it happens with everyone in the same way."
He finally won the Oscar for 1983's Tender Mercies. He played a recovering alcoholic country singer trying to start his life over. Duvall did his own singing in that film.
He directed 1997's The Apostle, which he also wrote, produced and starred in, as an evangelical preacher on the outs with God. It earned him his fifth Oscar nomination for acting.
Over the course of an acting career that spanned decades, Duvall appeared in over 90 films. He took traditional, old Hollywood archetypes of masculinity — soldiers, cops and cowboys — and imbued them with notes of melancholy, a vulnerability that made them come alive onscreen.
