Topline:
As predicted, Tropical Storm Hilary brought heavy rains to Southern California, particularly in the mountain and desert areas, which saw quite a bit of flooding and debris flows.
The forecast: Intermittent rain and thunderstorms are expected through Monday, but things should clear up my Tuesday.
Heaviest rainfall: Lewis Ranch in Los Angeles County saw 7.04 inches.
The storm formerly known as Hurricane Hilary has broken down and moved on to Nevada, leaving behind flooded roads, downed trees, stranded cars and soaked residents.
As predicted, Southern California's first tropical storm to make landfall in 84 years hit the mountains, foothills and deserts the hardest.

"It was uncharted territory as much for us forecasters as it was the public who found what we were saying pretty hard to believe," said Miguel Miller, a meteorologist with the National Weather Service. "We found it hard to believe ourselves, but we couldn't discount it. Couldn't deny it."
The center of Hilary passed over Los Angeles around 8 p.m. Sunday, though the heaviest rain fell between 2 and 6 p.m., dropping more than 1 inch per hour in some spots.
There have been no reports of any significant injuries or damage as of 8 a.m. Monday, though assessments are ongoing.
"We urge you to please be cautious of hazardous road conditions," L.A. Fire Chief Kristin Crowley said at a Monday morning news conference.
Still, the storm was felt across the region:
Across L.A. County, it was the San Gabriel mountains and the Antelope Valley that saw some of the heaviest bands of precipitation.

Rainfall totals as of early Monday:
Given how unusual it is for our region to see rain during this time of year, it's unsurprising that many daily rainfall records fell.
Flood watches are still in effect for Los Angeles and surrounding counties as the storm wraps up. They'll likely be lifted by Tuesday.
“We’ve made it this far. Let’s make it to the final home stretch here,” said Ariel Cohen, meteorologist in charge with the National Weather Service.

The city of L.A. is providing shelters to unhoused people at the following locations:
If you need to report a flooded road or a downed tree, you can call the following non-emergency numbers:
If you're in L.A. County and need sand bags, you can find them at local fire houses.
Dial 911 if it's an emergency.
As Hurricane Hilary approaches, it's important to have a safety plan in place. Advice from L.A. County Fire Department Chief Anthony Marrone:
A detailed list of emergency kit items can be found at ready.la county.gov; there will be real-time emergency updates on the county’s emergency website, found on the county’s landing page: LA county.gov/emergency.
The last time we were directly hit by a tropical storm was in 1939, when one made landfall in Long Beach, according to the National Weather Service in Oxnard.
While the track of this storm was unusual, the hurricane itself was not.
“So far this season has played out as expected,” said Jamie Rhome, deputy director of the National Hurricane Center.
Tropical cyclones regularly form off the coast of Southwest Mexico between May and November. While they usually track west out into the Pacific, they can head north toward Baja.
Sometimes they do indirectly affect Southern California. In September 2022, Hurricane Kay dropped more than 5 inches of rain on the area, causing flooding and damaging homes.
Topline:
For the rest of the year, Los Angeles residents won't get their water and power shut off if they can’t pay their bills.
The details: Mayor Karen Bass announced Tuesday that she asked the L.A. Department of Water and Power’s board to pause any residential shutoffs for nonpayment through the end of 2026. The request comes after a series of record-breaking heatwaves this summer and fall. A spokesperson for LADWP said the changes will be implemented immediately. The board is expected to formally vote to approve the ask at its next meeting, set for Oct. 27 at 10 a.m., according to a spokesperson for Bass. According to the LADWP spokesperson, customers who need assistance will get extra time to pay their bill by entering into a payment arrangement without any interest or late fees.
Bill breakdown: DWP bills two months at a time, and right now, many customers are being hit with one of their highest bills of the year — from August and September. In those months, 2% of DWP's 1.6 million customers received a bill of over $3,000, the DWP said; 3% were between $2,000 and $3,000; 12% were between $1,000 and $2,000; and 18% were between $500 and $1,000. At least 60% were under $500, the DWP said. LADWP says customers can call 800-DIAL-DWP (342-5397) if they have questions about their bills.
The backstory: As atmospheric pollution drives hotter, longer heat waves, utility bills are soaring too. That's why, in 2023, LADWP's board voted to end power shutoffs for all customers during extreme weather. Under that policy, LADWP will not shut a customer’s water and power off if they are delinquent on their bill when the National Weather Service has issued an extreme heat or cold weather advisory or warning. Outside of such weather advisories, however, customers can still face shutoffs. Under Bass’ request, shutoffs won’t occur through the rest of the year regardless of weather advisories.
Other resources: Bass encouraged customers to sign up for LADWP’s Level Pay program, which allows customers to pay off past-due bills over time or even out the peaks of high-energy-use seasons across a longer term. You can sign up and find other bill assistance programs on the DWP website.

Significant rain is in the forecast this week, just days after heat and Santa Ana winds fueled wildfires across Southern California
The rain: The bulk of the rain is expected on Wednesday night and Thursday morning. Most of L.A. and Orange counties could get around an inch, with more expected in the hills and mountains. There is also a chance of thunderstorms and hail.
Flood risk: A National Weather Service flood watch is in effect for the Santa Monica Mountains and surrounding communities. The area includes burn scars from last week’s Bryson Fire and last year’s Palisades Fire. Wildfire burn scars are susceptible to landslides and flooding during heavy rain.
Cooldown: Forecasters say the storm will bring cool air into southern California. Highs on Wednesday and Thursday will peak in the 60s and low 70s in most places. High elevations will likely be even cooler.
Read on … for more on this week’s forecast.
Southern California is likely in for a solid dose of rain this week, just days after heat and Santa Ana winds helped fuel several wildfires across the region.
Forecasters expect the bulk of the rain to roll into the Los Angeles basin Wednesday night and continue into Thursday morning, with a small chance of thunderstorms and hail.
The San Fernando Valley, San Gabriel Valley and coastal areas across L.A. and Orange counties could get around an inch over the next few days. Hills and mountains could get up to 3 inches.
“We could see some pretty high rain rates,” said National Weather Service meteorologist Mike Wofford. “It's a good storm for this time of year — it's a little stronger than what we would see normally.”
The possibility of significant rain in the mountains raises concerns about flooding in areas recently burned in wildfires, particularly around the Bryson Fire burn scar near Malibu, which is only a few days old. Burn scars can’t absorb heavy rainfall and are susceptible to landslides.
The National Weather Service has issued a flood watch for the Santa Monica Mountains and surrounding communities from Wednesday afternoon through Thursday. That means heavy rain there could flood streets, creeks and rivers. The flood watch area includes both the Bryson Fire and Palisades Fire burn scars.
This will also be the first nontropical storm of the season, meaning it’s moving into the region from the north. Most storms that hit Southern California follow a similar path, especially during the winter, unlike the tropical storms that formed off the coast of Mexico and brought muggy weather to the region this summer.
Nontropical storms also bring cold air to the region. On Wednesday and Thursday, forecasters expect highs in the 60s and 70s. High elevations will be even cooler.

The science research institute that would likely receive $4.2 billion in public taxpayer money if voters approve Proposition 38 this November had only three employees as of last month — far fewer than the 51 staffers it planned to have hired by last year. Public statements and public records CalMatters obtained raise questions about how well prepared the institute is to shepherd so much money if the bond measure passes.
Why it matters: Prop. 38 would allocate up to $8.4 billion in bonds for scientific research on diseases and cures concerning the immune system, with an emphasis on finding treatments for Alzheimer’s, cancer and heart disease. The ballot language stipulates that a single, unnamed research institute would receive half the bond’s money to conduct research and partner with other researchers if it meets highly specific criteria. Bonds are a type of debt that must be repaid. Previous reporting by CalMatters found only one institute in California currently meets those criteria: the California Institute for Immunology and Immunotherapy. The institute’s principal funder is billionaire Gary K. Michelson, who wrote Prop. 38 and is by far the largest donor to its political campaign.
What opponents say: The measure’s critics say Prop. 38 is well-intentioned but poorly designed because it overlooks the many established public and nonprofit university and hospital research labs in California. They also say California should not subsidize subsets of scientific research and instead should support research more broadly.

Backers of the proposition said state bond money is needed to stabilize research funding after President Donald Trump repeatedly attempted to cut existing and future federal science grants.
The measure’s critics say Prop. 38 is well-intentioned but poorly designed because it overlooks the many established public and nonprofit university and hospital research labs in California. They also say California should not subsidize subsets of scientific research and instead should support research more broadly.
CalMatters obtained documents that included the five-year business plan of the California Institute for Immunology and Immunotherapy. The plan was part of the formal affiliation agreement between UCLA and the institute, which the two parties signed in August 2024. Among other details, the agreement requires the institute to pay UCLA 7.5% of the net revenue of any drugs and technologies developed by the institute’s staff. The institute is one of the founding tenants at a UCLA-owned research park in West Los Angeles, where the institute is leasing 235,000 square feet of research space, the institute says.
Between summer 2024 and summer 2025, the institute committed to hiring “approximately” 51 employees, including six executives, five “world-class” scientists who can lead research labs, and 40 other employees, such as data scientists, lab technicians, biologists and administrative personnel. Between 2025 and 2027, the institute would hire roughly 90 more workers, including 10 research lab leaders, according to the agreement.
But John Mazziotta, a senior UCLA official who also serves as a board member of the immunology institute, last month said the institute has hired just three employees: a chief operating officer, a general counsel, and a scientific advisor, and “they're well into the search” for a director. Mazziotta, the CEO of UCLA Health and vice chancellor for health sciences at UCLA, made his comments during the Sept. 16 UC Regents meeting.
The Yes on Prop. 38 campaign has repeatedly refused to comment on whether the bond was written specifically for the immunology institute. Claudia Briggs, a spokesperson for the campaign, told CalMatters in July that whichever nonprofit receives the $4.2 billion portion of the bond fund should be a sophisticated one that “is prepared to accelerate lifesaving research immediately while maintaining the highest standards of scientific quality, accountability, and stewardship of public funds.”
At a September press conference, a Yes on Prop. 38 spokesperson appeared to confirm CalMatters’ findings that only one institute currently qualifies to be the one to receive half the bond money. “It is very likely that CIII, which is a research institute affiliated with UCLA, will qualify for half of the funds under the current criteria,” said Robin Swanson. CIII is the initialism for the immunology institute.
According to the five-year plan, the institute was supposed to spend $25 million on personnel between 2024-25 and 2025-26 and $45 million total on operating expenses in that time, including maintenance, utilities and rent. It was also supposed to spend an additional $167 million in that time on capital expenses, such as construction and demolition. However, Mazziotta told UC regents that the institute had so far spent a total of $20 million on “operating expenses, hires” and other expenses.
The Yes on 38 campaign refused CalMatters’ request to interview Michelson for this story, as did Michelson himself in a separate email. A spokesperson for the institute, Becky Warren, sent a written statement that didn't answer CalMatters' questions about employing far fewer people than the five-year plan laid out. Instead, she highlighted the promise of the institute and a few of its milestones, including signing the affiliation agreement with UCLA and clearing a state environmental review of its forthcoming research facility.
The institute won’t get state bond money if it isn’t ready to begin work, “plain and simple,” wrote Swanson, the Yes on 38 spokesperson, in an email. She stressed that though the institute very likely qualifies, the ultimate decision to award half the bond funding is up to the California Department of Public Health.
The UCLA research park that houses the institute isn’t slated to be fully built until at least late 2028, according to the agenda item of the September UC regents meeting. The research park is a former mall UCLA acquired in late 2023 that’s now undergoing major retrofitting.
But the 2024 affiliation agreement between UCLA and the institute anticipated this. The agreement permitted the institute to use UCLA health research space on another campus property on an interim basis. Mazziotta told regents that research is underway there.
Mazziotta also told the regents the institute's construction costs are not fully funded — it still needs roughly $100 million. He said UCLA was in serious talks with a donor to provide about $50 million to the institute.
If Prop. 38 passes, the bond funding would be provided in increments based on how often the institute requests new money that senior state officials approve. If all the funds are depleted, Californians would repay the bond at a rate of $500 million to $600 million annually for about 20 years.
CalMatters submitted the public records request to UCLA, which must comply with the California Public Records Act. The institute, as a private nonprofit, does not have to comply. And while Prop. 38 would channel billions of dollars in taxpayer money to the institute, the proposition’s language specifically exempts the nonprofit that will receive the $4.2 billion from state public meetings laws, political reform laws and the public records act. The other half of the funds would go to a council that’ll pick projects led by researchers from a limited pool of universities and nonprofits. The council would generally be governed by the state’s political reform act, which prohibits financial self-dealing.
Briggs defended the institute’s exemption in Prop. 38, writing that applying state transparency laws to existing private organizations would “not fit well with how private entities are organized and operate.” Instead, she noted the selected nonprofit institute would be required to publish annual reports on its research progress and financial plans plus commit to annual state audits, among other disclosures written into the ballot measure.
Still unclear to the UC regents is the relationship between UCLA and the institute on matters of public disclosure. Four senior UCLA officials sit on the institute’s board. So is a document held by those UCLA officials public because it’s related to UCLA affairs or private because it’s related to the institute’s affairs? UC’s general counsel couldn’t explain where that dividing line is after a regent member asked him. The regent member, Michael Cohen, said he wants more clarity when the regents meet again in November.
Gov. Gavin Newsom and the California Democratic Party endorsed Prop. 38, as have dozens of patient and research advocacy groups, plus the state GOP. The union of graduate students and post-doctoral researchers, whose pay often relies on science research funding, has also endorsed the proposition. The union doesn’t represent faculty.
Money raised in support of Prop. 38 now exceeds $66 million, including at least $61.2 million in contributions from Michelson and his policy institute. Roughly $14 million of that includes loans from Michelson. The no camp has raised about $8,800
