California “snow deluges” expected to decline significantly by 2100
Extreme snowfall will become less common in California by 2100, a new study found.
Scientists understand how a lack of snow or “snow drought” can affect a region, especially in the midst of a warming climate. However, before now, they did not understand the impact of unusually high levels of snow. And this is becoming more important, as California has just emerged from its second winter of high snowfall.
A new study published in the Proceedings of the National Academy of Sciences used the 2023 winter as a case study to learn more. Computational hydrologist Adrienne Marshall and colleagues from the Colorado School of Mines dubbed the term “snow deluges” to describe the phenomenon recently seen in California.
To reach their findings, they analyzed the unusual snow deluge across the Sierra Nevada mountains in 2023 to assess the impact of “high snow years.”

In 2023, California saw an extremely high amount of snow accumulation, with record snowpack levels. Observations showed the accumulations were a “once-in-54-years event,” with some areas reporting “once-in-320-years accumulations,” the study reported.
By looking at climate projections, scientists found that years like these with the so-called “snow deluges” are set to decline by 58 percent by the end of this century. Years with median levels of snowfall are also estimated to decline by 73 percent, they reported.
“California’s massive snow year of 2023 was record-breaking at 42 percent of snow monitoring sites,” Marshall told Newsweek. “Climate models indicate that in warmer future climates, our biggest snow years will be smaller than our biggest snow years now. Another way of putting this is that a snow deluge like we saw in 2023 would be much more rare in a warmer climate like that we might expect later in the 21st century.”
Similar patterns will also be seen across the wider Western U.S., the study reports.
The findings “underscore the significance of uncovering the impact of climate change on the dynamics of snow deluges and snow droughts in mountainous regions,” the study reports.
“These findings align with a bigger scientific picture that shows declining average snowpack and more frequent snow droughts in California and throughout the West,” Marshall said. “Our new findings suggest that we shouldn’t count on big snow years like the one we had last year to save us in warmer climates.
“This is important because snow acts as a natural reservoir in the mountains that stores water until the late spring and summer when we need it most. Our best opportunities to avoid the worst consequences of this snow loss lie in reducing our greenhouse gas emissions and finding ways to adapt to adapt to changing snow and water availability.”
The study notes that snow deluges can be “both destructive and beneficial” meaning better understanding of the phenomenon can improve management of “snow-dependent ecosystems and economies.”
The 2023 snow deluge in California, in many ways, could be seen as good thing. Before it occurred, the state had been suffering from prolonged drought conditions. As a result, there was a severe lack of snowpack in the surrounding mountains, meaning less water was feeding the state’s reservoirs.
The large snow build-up, however, meant that come spring, it melted into rivers and reservoirs, saving the state from a water crisis. In fact, drought conditions in the state officially ended.
However, the heavy snowfall indicates that climate change is worsening, as weather patterns become more unpredictable and extreme. While the drought has ended for now, climate change could cause another prolonged dry period in the future.
“Snow is important for both ecosystems and water resources, and there’s a lot still to learn about how our biggest snow years—or the loss of them—impact these systems,” Marshall said. “The present study focuses on annual-scale snow deluges, but the largest individual snowfall events could change in different ways.
“We focused on a moderate warming scenario in California and the Western U.S., but it would also be helpful to learn more about how different climate scenarios could affect snow deluges in other parts of the world.”

As the nation prepares for its 250th Independence Day celebration, a decades-long California Fourth of July fireworks tradition that has raised millions for local children’s programs is going dark this year after the California Coastal Commission rejected a final effort to keep it alive, citing environmental concerns to protect the bay.
“We’ve raised over the past 14 years $2 million for kids programs here in Long Beach,” event organizer John Morris told Fox News Digital, adding the July 3 event is fully funded by the local community.
“This community pays for everything — everything. City fees, and the city doesn’t give us a break. We pay $20,000 to the city for police and fire, which I’m fine with, because there’s 100,000 people enjoying the fireworks,” said Morris, a Long Beach resident and business owner.
Morris, who owns the Boathouse on the Bay restaurant, had planned a scaled-up fireworks display this year to mark America’s 250th Independence Day.

In January, Coastal Commission staff rejected the proposal, and last week commissioners unanimously upheld that decision despite an appeal backed by local, state and federal officials.
Regulators warned Morris last year that 2025 would likely be the final year for fireworks at the event, as they continue pushing organizers to switch to drone shows they say are more environmentally friendly.
The decision stands in contrast to other approvals by the commission, including a permit granted to SeaWorld allowing up to 40 nights of fireworks.
“They get 40 nights in Mission Bay. All I’m asking for is 20 minutes — it doesn’t make any sense,” Morris said.
Morris, 78, also pushed back on the environmental concerns cited by the commission, pointing to years of testing around the event.

Due to the lack of fireworks, Morris has decided to cancel the July 3rd celebration.
“We’ve had 10 years of environmental studies,” Morris said. “We test the water before and after the fireworks and send a robotic camera into the bay to check for debris — there’s never been any. It’s been spotless.
“We’ve also had eight years of bird reports to make sure we’re not harming wildlife. We’ve never had an issue. We’ve never been written up one time. So what is it really about?”
Joshua Smith, a spokesman for the California Coastal Commission, told Fox News Digital that permits are determined on a case-by-case basis, citing environmental concerns to “protect the bay.”

Smith said Morris was approved for a permit to hold a drone show in lieu of fireworks. Morris told Fox News Digital such a show would cost about $200,000 — roughly four times more than traditional fireworks.
Smith confirmed that SeaWorld received a permit allowing 40 nights of fireworks. When pressed on the discrepancy, he reiterated that decisions are made individually and declined to provide further details.
Morris said the loss of the fireworks show will be felt across the community, from local businesses to families who have made the event an annual tradition.
LOS ANGELES (AP) — In the wide-open race for California governor, billionaire Tom Steyer is on a spending binge.
The hedge fund manager-turned-liberal activist is using his personal fortune to saturate TV screens and mobile phones with advertising, while his competitors accuse him of trying to use his vast wealth to buy the state’s most powerful job.
Steyer’s ads — in which he promises to bring down household costs or rails against federal immigration raids — appear inescapable at times in heavily Democratic Los Angeles, the state’s largest media market. Data compiled by advertising tracker AdImpact show Steyer has spent or booked over $115 million in ads for broadcast TV, cable and radio — nearly 30 times the amount of his nearest Democratic rival.
If he makes it through the June 2 primary election, Steyer could easily eclipse the 2010 record set by Republican Meg Whitman, who spent $178.5 million in a losing bid for governor, much of it her own money. At the time, it was the costliest campaign for statewide office in the nation’s history.
Even when ad buys from all his major competitors are combined, along with ad purchases by independent committees supporting candidates, Steyer is outspending the field by tens of millions of dollars.
“Billionaire money is flooding our state in an attempt to buy this election,” former U.S. Rep. Katie Porter, one of Steyer’s chief rivals, warned her supporters this month.
Mail-in ballots are set to go out to voters next month. Steyer is among a crowd of candidates hoping to seize a spotlight after former Democratic U.S. Rep. Eric Swalwell’s dramatic departure from the race following sexual assault allegations that he denies.
But while Steyer has ticked up in polling amid his spending splurge, he has not broken away from the field, leaving some wondering if he’s getting value for his dollars.
“If your first round of ads doesn’t move you dramatically (in the polls), the third, fourth, fifth, six, seventh and eighth rounds won’t either,” said veteran Democratic strategist Bill Carrick, who for years advised the late Democratic U.S. Sen. Dianne Feinstein. “There is something inherently holding Steyer back.”
In recent prior campaigns for governor, at this stage a leading candidate was taking control of the race. This year, voters appear to be shrugging at a contest that lacks a star candidate among seven leading Democrats and two Republicans.
“Somehow the campaign is frozen,” Carrick added.
History shows that money doesn’t always translate into votes.
Billionaire developer Rick Caruso spent over $100 million in 2022 in his bid to become Los Angeles mayor, much of it his own money, but he was handily defeated by Mayor Karen Bass, who spent a fraction of Caruso’s total. Billionaire former New York City Mayor Michael Bloomberg spent more than $1 billion of his own money on his 2020 presidential bid before dropping out. And Steyer’s money was unable to lift him into contention in the 2020 presidential contest, when he dropped out early in the year after a poor finish in the South Carolina primary.
Steyer has never held elected office.
In a 2019 interview with The Associated Press, Steyer was asked what he would say to people who think he’s trying to buy the presidency.
“I don’t think that’s possible,” Steyer said at the time, before adding, “I’m never going to apologize for succeeding in business. That’s America, right?”
His campaign did not respond directly when asked about similar criticism facing his run for governor.
“Tom now stands as the only Democrat with the grassroots energy, institutional backing and resources to advance to the general election,” spokesperson Kevin Liao said in a statement.
The governor’s race was recently reordered by two developments: Swalwell, a leading Democrat, abruptly withdrew from the race then resigned from Congress, following sexual assault allegations. Meanwhile, President Donald Trump endorsed conservative commentator Steve Hilton.
Still, there is no clear leader.
Polling in late March and early April by the nonpartisan Public Policy Institute of California found a cluster of candidates in close competition: Democrats Steyer and Porter, Republicans Hilton and Chad Bianco, and Swalwell. Other candidates were trailing. The polling was conducted before Swalwell withdrew.
Democrats have feared the party’s large number of candidates could lead to them getting shut out of the general election in November. That’s because California has a primary system in which only the top two vote-getters advance to the general election, regardless of party.
Leading Democrats are all claiming to have picked up support since Swalwell’s exit. Steyer nabbed one plum endorsement, when the influential California Teachers Association, which previously backed Swalwell, recommended him.
In his ads, Steyer promises to “abolish” U.S. Immigration and Customs Enforcement, which has been staging raids across California. In another, he laments the state’s punishing cost of housing, “Everybody needs an affordable place to live,” he says.
Rapper was stabbed 16 times by fellow inmate in May 2025 while 10-year sentence in Megan Thee Stallion shooting case
Tory Lanez has filed a $100 million lawsuit against the California Department of Corrections stemming from a May 2025 incident where the rapper was stabbed in prison.
Lanez — born Daystar Peterson and currently serving a 10-year sentence after being found guilty in the Megan Thee Stallion shooting case — also sued the warden and guards at the California Correctional Institute in Tehachapi, where the rapper was stabbed 16 times in an “unprovoked life-threatening attack” by another inmate, the lawsuit states.
Peterson was hospitalized following the May 2025 incident, suffering a collapsed lung among stab wounds to his back, torso, and head.
According to the Associated Press, the lawsuit criticized the Department of Corrections for housing Peterson with fellow inmate and alleged attacker Santino Casio, who was serving a life sentence for second-degree murder. “The choice to house Casio with Peterson was known or should have been a known danger,” the lawsuit said, adding that Tory Lanez’ “high-profile celebrity status” made him a target.
The lawsuit also said that prison guards were slow to respond to the shanking, and didn’t employ flash grenades or other measures to halt Casio’s attack.; Casio was not charged for stabbing Peterson, the Associated Press notes.
Lanez, who following his hospitalization was transferred to San Luis Obispo County’s California Men’s Colony, also alleges in the lawsuit that he never received his possessions from the California Correctional Institute in Tehachapi, including songbooks filled with lyrics to his unreleased music.
Lanez is serving a 10-year prison sentence for shooting Megan Thee Stallion in the foot during a confrontation in the summer of 2020. He was eventually convicted on several firearms charges, including assault with a firearm, in December 2022. In November 2025, his appeal was denied by a three-judge panel, and the 10-year sentence was upheld.
