The Brief

California is in the midst of a strong atmospheric river that's caused flooding, evacuations, road closures, and mention of it is all over the news and social media. And this comes on the heel of twoprevious winters where the Golden State saw damaging storms of the same kind. If you have the feeling that in the past few years, you've started hearing the term a lot more, you are not alone. You're not even wrong.

In recent years, "atmospheric river" has become used much more frequently in scientific papers and in media coverage. According to experts who study climate and weather, a couple reasons may explain why. Technical weather terms in general are now more used in the news. Atmospheric rivers are a thriving area of research, more of which may be filtering into media coverage. And these storms are also expected to intensify and become more damaging as the climate warms – which means there's more attention on them.

What is an atmospheric river anyway?

Before we get into why we're hearing about them more, let's go over the basics of what an atmospheric river is.

These storms have always existed. They occur around the world, often on the west coasts of the mid-latitudes, where an ocean meets a landmass. They're long filaments of concentrated water vapor in the lower atmosphere occurring along with strong winds – and they're the primary way water is moved horizontally. In California, a normal winter might see five of these kinds of storms and as many as 20 could occur during wet winters. A typical one can be 300 miles wide, a mile deep and 1,000 miles long. When plotted on a map or looked down upon from a satellite in space they looked just like rivers.

For a long time, they were colloquially and scientifically referred to as things like the Pineapple Express or Rum Runner Express. Those turned out to be just a subset of atmospheric rivers however, ones that originated near Hawaii or in the Caribbean heading toward Europe. Not all ARs are particularly warm or begin in those locations.

"So the 'atmospheric river' term is the broader envelope," says Daniel Swain, climate scientist at the University of California.

The term was coined in a 1994 paper by two researchers at the Massachusetts Institute of Technology.

"And it turns out that they are very comparable to terrestrial rivers in terms of how much water is moving in them," Swain said. "In fact, sometimes they're significantly greater even than some of the flow of the largest terrestrial rivers on earth," including the Mississippi or Amazon River.

How we talk about the weather has changed

Swain believes that one reason people are suddenly hearing about atmospheric rivers more is because those who communicate about weather to the public have made a shift to using terms that the scientific community uses.

"I think a lot of it probably has to do with the media landscape and the popularization of certain technical weather terms," he said, pointing to "bomb cyclone" and "bombogenesis" as other examples. These are formal, quantitatively defined meteorological terms, "and everyone assumes that's just some invention of the social media hype era."

In fact, he says, these seem to date back to the 1940s during World War II when meteorologists were advising Allied forces in the North Atlantic Theater.

Atmospheric river, he says, is similar.

"Instead of just making something up out of the ether," Swain says, "there's been an interest in what are actually meaningful, technically correct scientific terms to describe various weather phenomena, which I'm not so sure is a bad thing."

Scientists have done a lot to understand atmospheric rivers better

In recent years, ARs have been a blooming area of research, some of which is filteringinto mediacoverage.

Marty Ralph, director of the Center for Western Weather and Water Extremes at Scripps Institution of Oceanography, has been a pioneer in the field and is frequently cited in the press.

Researchers like Ralph have helped discover how important atmospheric rivers are, both for California but also for storms around the country and world. Back in 2004, the topic had fallen out of favor, says Ralph. But with new data collected by aircraft and satellites he showed researchers how to see the storms in a new way, allowing scientists to observe them from the inside and out.

"I sort of resurrected the topic after an early pullback," Ralph said.

This now-vibrant area of research has made some recent discoveries, says Ralph, including how to better predict their effects, how they impact both snowfall and snowmelt in the polar regions and links between AR intensity and climate change.

"Because a warmer atmosphere holds more water vapor and water vapor is the fuel in atmospheric rivers, ARs can carry more water vapor," Ralph says. "And there are studies now that show we can expect to see somewhat more extreme ARs and more common, in some cases, just because of that."

The weather news in California has flipped from being about drought to being about storms

What may increase the impression that atmospheric rivers are a new thing is that for a good part of the past decade, California was in serious drought and wasn't getting them. Then in early 2023, multiple AR storms followed one after another, resulting in flooding around California and 22 deaths.

"In both cases, it's a story about atmospheric rivers, in one case a deficit of atmospheric rivers, not enough of them, and the other case overabundance – too many atmospheric rivers all at once," said Swain. "California water lives and dies by this."

Atmospheric rivers are at fault in more than 80 percent of flooding across the West. On average these storms cause $1 billion in damage each year.

A look at Google Trends, reveals an early blip of interest in atmospheric rivers in early 2011, hardly anything during the drought years of 2012-2016, then more blips in 2017, 2019 and 2021 coinciding with West Coast storms and flooding. And finally large spikes in interest in 2023 and 2024. So far this fall has only brought one AR to California, but it is a record-breaking one.

A major development for the future of atmospheric river research, says Ralph, is the possibility of improving our forecasting up to two weeks before a storm.

Legislation introduced on Wednesday by Senators Alex Padilla (D-Calif.) and Lisa Murkowski (R-Alaska) seeks to secure funding to increase airborne reconnaissance – using planes to fly through the storms – to learn more about atmospheric rivers.

"The more we sample these storms, the more accurate the forecasts become," said Ralph.

Felt around the country

Lest you think these storms are purely a West Coast phenomenon, researchers are increasingly appreciating ARs role in fueling and directing nor'easters, strong storms that impact the East Coast.

"It's quite possible that AR recon in the Gulf of Mexico and off the East Coast will actually be able to improve the forecast scale of the track and intensity of nor'easters," Ralph said, "which people in the East know full well, is a very important detail in order to determine if the big cities are impacted."

NPR audiences first heard about atmospheric rivers in 2013, when Jon Hamilton offered "Tips for Surviving a Mega Disaster."

When it comes to renters, Scorpios are “particular,” Libras are “gold,” and Aquariuses “can't make up their mind.” That’s according to Dave Goldstein, the Los Angeles landlord behind the company Art Deco Apartments.

For years, Goldstein has asked prospective tenants to tell him their astrological sign as part of the application process. He said he doesn’t care about credit scores, and he loves tenants with pets. He knows his approach to tenant screening is unusual. But when it comes to picking the right renters for his century-old, tastefully appointed buildings, he said it works.

“It gives me an idea of their personality,” Goldstein told LAist outside The Mauretania, a well preserved example of 1930s Streamline Moderne architecture in Hancock Park.

“I mean, it's impersonal to just get an application,” he said. “You're going to get buildings that aren't that good. You're going to get impersonal people that don't care about anything.”

The question might be helpful to Goldstein, but some housing rights experts say it could be pushing the boundaries of what’s legal.

Why Leos make good tenants

While he hasn’t blacklisted any particular star sign, Goldstein said in his experience, people with certain signs are easier to deal with as tenants.

“If they say that they're a Leo, I go, ‘Great,’” he said. “‘I can't wait to rent to you. You're your own boss. I don't have to do nothing. You'll change every light bulb. You'll never call us.’”

Goldstein also likes to ask tenants where they grew up and the color of their car. He said people are sometimes surprised by the questions, but they tend to like his approach.

“They just can't believe it, because they're used to just texting a management company,” he said. “They're not used to personal service.”

The Mauretania, a 1930s apartment building with distinctive curved windows looking out on the street, is one of the properties Dave Goldstein owns through Art Deco Apartments.

Housing rights lawyers weigh in

But is asking a tenant about their astrological sign legal? Housing rights attorneys told LAist they’re not aware of any laws or court rulings that explicitly ban landlords from screening tenants based on their birth month. But they said the question is still legally precarious.

“There's not a specific law against it,” said Rodney Leggett, director of litigation at the L.A.-based Housing Rights Center. “But because of the seemingly arbitrary nature of asking somebody about their astrological sign, it could potentially violate the [California Unruh Civil Rights Act].”

The law bans businesses from discriminating against people based on personal characteristics including sex, race, color, religion, ancestry, national origin, disability, medical condition, genetic information, marital status or sexual orientation.

It does not specifically mention astrology. But lawyers said depending on how businesses treat people with different signs, an argument could be made that they’re being discriminated against for no legitimate business reason based on a personal characteristic they can’t control.

“Astrological signs are not a traditional ‘protected characteristic’ in most anti-discrimination laws,” said Alisa Randell, a managing attorney with the legal aid organization Public Counsel. “But we do have this expansive law in California that is not limited to the categories that are laid out… So I think this is dicey for him.”

Goldstein said he has tenants of all astrological signs, and he plans to keep asking applicants about their birth charts.

“I don't know if it's legal to ask about it or not,” he said. “But it's fun to. And I know they're not going to lie about it.”

Gov. Gavin Newsom has proposed record levels of public funding for K-12 schools, but in several Southern California school districts declining enrollment and rising costs may still lead to cuts next school year.

The budget proposal allocates $125.5 billion, the highest-ever level, according to Newsom. That’s $20,427 per student.

“There's an increase in per pupil funding, but I wouldn't be fooled into thinking that those numbers indicate that schools really have more money to work with than in previous years,” said California School Boards Association spokesperson Troy Flint. The organization represents almost 1,000 districts and county offices of education statewide.

That’s because declining enrollment combined with rising teacher salaries, un-funded state mandates and other increased costs are squeezing local school districts.

LAist spoke to Flint and several other school finance experts to understand the financial challenges California districts face as they create their spending plans for next school year.

How does the state fund school districts?

The majority of the state’s general fund comes from personal income, sales tax and corporation tax revenue.

“That's great when the economy is good and state revenues are growing, and it's trickier when the economy is bad and state revenues are small,” said USC education professor Lawrence Picus.

California law guarantees TK-12 schools and community colleges a minimum level of funding each year, usually about 40% of the state’s general fund. (Property tax is a local revenue source, and considered to be less volatile but with limited growth.)

The state provides a base amount of money multiplied by each student and there is additional funding for every low-income, English-language learner, unhoused or foster youth student in the district. This system is called the Local Control Funding Formula.

How does enrollment affect school funding?

Since California sets funding rates per student, it needs a way to count those students. This is average daily attendance — how many students show up for class each day.

Currently, fewer students are enrolling at schools throughout the state, particularly in areas with high costs of living like Los Angeles. Students who are enrolled are also missing more school compared to before the pandemic.

“The intuitive response is, ‘well, if you have declining enrollment, you have fewer students, you should need less money,’” Flint said. “But in practice it doesn't really work that way.”

That’s because a district may lose a few students from each class across several schools each year, which may not justify laying off staff or closing a campus.

California education law blunts the immediate impact of declining enrollment by calculating funding based on the highest of three attendance counts: current year, prior year, or the average of the three most recent years, but over time fewer students means a smaller multiplier for state funding.

Increasing costs

Michael Fine is CEO of Fiscal Crisis and Management Assistance Team (FCMAT), the California agency that supports public schools' financial and business practices. He estimated schools are experiencing an estimated 5-6% cost increase every year.

The sources of that increase can include an increase in sexual assault claims (and the ensuing legal costs), utilities and insurance costs.

California provides money toward these increased costs through the Cost of Living Adjustment (COLA). This year’s proposed COLA is a 2.41% increase, less than half the estimated increase districts are experiencing, Fine said.

“At the state, they can say we are fully funding our commitment to TK through 12 education,” Fine said. “But at the local level, it feels like things are constrained. It feels like a pinch or actually a reduction.”

Another factor is the push to increase educators’ salaries in light of California’s high cost of living.

This year unions representing teachers at 32 school districts, including Los Angeles Unified, are negotiating contracts under a unified platform called “We Can’t Wait.” The campaign has already led to one strike and negotiations have stalled in more than a dozen districts, including LAUSD.

Federal, state budget uncertainty

This year’s state revenue projection is higher than expected, in part because of high salaries tied to artificial intelligence, but there’s no guarantee the funding will last.

Alix Gallagher studies school finance at Policy Analysis for California (PACE) and said that because revenue is unpredictable, lawmakers often opt to fund short-term initiatives rather than make long-term commitments.

“Whatever positive effects we're seeing [from short-term funding] are not the types of positive effects we might see if our funding was more stable,” Gallagher said.

For example, this year there is $1 billion for community schools, $757 million to support learning recovery related to the COVID-19 pandemic and $22.9 million for schools damaged by the January 2025 wildfires in L.A. County.

The budget also includes a one-time $2.8 billion grant that can be used for a variety of purposes from filling in the funding gap left by declining enrollment to supporting teacher training.

“Many districts will use that to mitigate some of their struggles,” Fine said. “All it does is buy time.”

The federal government also provides some money for education, but it’s also unclear how that funding will change in the second year of the Trump Administration’s second term.

In 2025, there were cuts to migrant education, mental health, and some internet access programs, although the courts ordered the administration to restore funding to several programs including teacher-training and afterschool programs.

What’s next for California school funding?

Newsom will present a revised spending plan in May and California lawmakers have until June 15 to pass the state’s budget.

In the meantime, local school districts will begin crafting their own budgets based on the governor’s proposal.

Fine said district administrators and elected school boards will have to manage the financial consequences of declines in enrollment over time.

“They make the hard decisions, their boards make the difficult, hard decisions to make, cuts to services and programs,” Fine said.

How can I monitor my school district’s financial health?

School budget proposals should be presented at public meetings, often the school board, where elected leaders can ask questions and the public can weigh in.

Districts may also create a working group, often called a budget advisory committee, of staff, families, community members and students to come up with a plan to address the district's financial challenges.

One indicator of your school district’s financial health are interim reports due in December and March to the County Offices of Education. These reports show how and whether the district can meet its financial obligations for the current and two following years and are labeled:

• Positive, the district can meet its obligations
• Qualified, the district may not be able to meet its obligations
• Negative, the district cannot meet its obligations without changes

Two of Orange County’s 32 districts filed qualified reports in December— Cypress and Saddleback Valley Unified. LAist has also requested this information from the Los Angeles County Office of Education and will update this article when we hear back.

$8.63 million in emergency grants sent to 562 families.

That’s how much financial assistance the Entertainment Community Fund has provided to performing arts and entertainment industry workers since fires broke out in Southern California in January last year. And the organization still is distributing grants, with the knowledge that needs are likely to increase soon.

 ”We know that the trajectory of the recovery process with homeowners and their insurances is that they will often pay some portion or all of a rent expense while people are displaced from their homes,” says Keith McNutt, the ECF’s Western Regional director. “That usually only lasts nine months to a year, and we're of course coming up on that year.”

Why entertainment workers?

Providing support to the entertainment community is nothing new for the nonprofit Entertainment Community Fund (formerly known as The Actors Fund), a national organization that’s been around since 1882 and is a sort of safety net for arts and entertainment workers in any kind of need or crisis. They also have built some of their own affordable housing.

A significant portion of their work, McNutt says, is making people aware that help is available and also that it’s OK to access it.

“It’s hard for any professional person in their craft to ask for help from anyone,” McNutt says. “But literally, we were created 140 years ago for exactly that reason. Because people work hard in this industry, but the industry doesn't provide regular income, regular benefits, [...] predictability, a standard career ladder.”

On top of the normal unpredictability factors of a career in the performing arts, there’s also the fact that the past five years have been “such a brutal onslaught of crises,” as McNutt describes it, from the COVID-19 pandemic to the WGA and SAG-AFTRA strikes in 2023 to the January 2025 fires, “that people have not had time to recover.”

What help is available?

The Entertainment Community Fund’s staff of social workers, career counselors and health insurance counselors provides a wide range of services (many of them free), like classes on things like building “parallel” or “sideline” careers to supplement income and support groups (including some specifically designed for people impacted by the 2025 fires).

Some services, like emergency financial assistance, require a more formal application to show that a recipient does in fact work professionally in performing arts or entertainment.

From ‘parallel’ careers to career changes

For a long time, McNutt says, he heard from arts professionals who saw their non-arts-related day jobs (ECF calls them “parallel” or “sideline” jobs) as sort of betrayal of their art, but “ our message has always been, ‘No, no, no [...] that's what helps you stay in your creative craft.’”

Over the past couple of years, though, with hardships compounding and  ”profound shifts in the amount of employment, particularly in television and film,” McNutt has seen something different.

“We have seen significant increases in the number of people who are coming to our career center to consider transitioning to other careers," he says. "And that is definitely a change.”

And even for those cases and questions like, “How do you apply for a job that's not in the industry when you've never worked outside the industry?” McNutt says that's "something we can help people with.”

A three-judge panel ruled Wednesday that the new congressional maps created by California voters in the fall are legal and should remain in place, handing a win to state Democrats who hope the new districts will swing five congressional seats for their party next year.

The ruling denies a request by California Republicans and the Trump administration for the federal court in Los Angeles to issue a preliminary injunction blocking the maps created by Proposition 50.

In the 117-page ruling, the federal judges rejected GOP arguments that the new maps amounted to racial gerrymandering, which has been prohibited by the U.S. Supreme Court. The panel ruled 2-1, with the two Democratic appointees ruling for California and Judge Kenneth K. Lee, who was appointed by President Donald Trump, dissenting.

In the opinion, Judge Josephine Staton wrote that the panel’s conclusion “probably seems obvious to anyone who followed the news” about Proposition 50 last year. She noted that during the campaign, no one ever described the new maps as racially motivated — including the Republican plaintiffs.

“No one on either side of that debate characterized the map as a racial gerrymander,” the opinion states, noting that the California Republican Party called it a “political power grab to help Democrats retake Congress and impeach Trump,” and Attorney General Pamela J. Bondi deemed it a “redistricting power grab” for political gain.”

The judges also rejected Republican arguments that the voters’ intent did not matter. The majority wrote that voters clearly were endorsing the argument that both sides were making: that this was a partisan power grab, aimed at giving Democrats a leg up in the midterm elections and counteracting what GOP-led states were doing with their own districts.

Democrats celebrated the ruling.

“Republicans’ weak attempt to silence voters failed. California voters overwhelmingly supported Prop 50 — to respond to Trump’s rigging in Texas — and that is exactly what this court concluded,” Gov. Gavin Newsom said in a statement.

Newsom pushed lawmakers to put Proposition 50 on a special statewide ballot after Trump set off a mid-decade redistricting scramble by demanding Texas redraw its maps to benefit Republicans.

In his dissenting opinion, Lee wrote that race “likely played a predominant role in drawing at least one district because the smoking gun is in the hands of Paul Mitchell,” referring to a Democratic consultant who helped draw the new lines.

Lee argued that Mitchell publicly “boasted” about boosting Latino voting power in the 13th Congressional District in theCentral Valley, and that voter intent should not be the only basis for the court’s decision.

“To be sure, California’s main goal was to add more Democratic congressional seats. But that larger political gerrymandering plan does not allow California to smuggle in racially gerrymandered seats,” said Lee, who wrote that Democrats likely wanted to create a Latino majority district “as part of a racial spoils system to award a key constituency that may be drifting away from the Democratic party.”

The ruling could be appealed to the U.S. Supreme Court.

Congressional candidates have until March 6 to file papers to run for office in the June primary.
