The Brief

Hilary is officially a tropical storm, according to the National Weather Service. So no longer a hurricane, but it's forecast to pack a wallop still, with heavy rains and wind, bringing potential flooding and mudslides.

• The rain has started to hit many areas in Southern California, with the most intense rain and wind striking at night and sticking around into Monday morning. Rainfall in the city of Los Angeles is expected to total about 1.5 to 3 inches, with winds from 20-30 mph.
• Conditions are expected to be much worse in the valley and mountain regions. At a press conference Sunday morning, L.A. Fire Department Chief Kristin Crowley said those areas can expect 3 to 7 inches of rain and Santa Ana-like winds up to 40 mph, with gusts to 50 mph.
• A state of emergency is in effect for much of Southern California.
• All state beaches in Orange and San Diego counties are temporarily closed. Camping is canceled in affected areas, and some inland parks are closed due to flooding concerns. 
• The L.A. Unified School District will announce later in the day on Sunday whether schools will be open or closed on Monday.
• Flash flood warnings and watches are in effect throughout the region.

Here’s an excerpt from our guide to understanding flood warnings:

• 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.
• A flood 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.

Forecast and conditions

The storm was downgraded from a hurricane to a tropical storm by the time it reaches us, in part because colder waters off our coast deplete the energy needed to sustain a hurricane.

Our dramatic, mountainous topography will also help to break up the storm, according to Paul Iñiguez, meteorologist with the Center for Western Weather and Water Extremes at the Scripps Institute for Oceanography.

“They’re large speed bumps in the air,” he said.

Rainfall totals could reach 6+ inches in our desert areas according to this forecast from August 18.

The difference between a hurricane and a tropical storm is wind speed, and regardless of what Hilary is downgraded to, one thing's for certain: it's going to bring enough rain to threaten communities, particularly those in the mountains and deserts.

We could see flash floods across the southwestern U.S., particularly in desert areas due to Hurricane Hilary.

Tropical storm and flood watches have been issued by the National Weather Service for counties across Southern California.

What else you should know

• Rainfall: Expect 2-4 inches across many metro areas, and potentially more than 6 inches in the mountains and deserts. Rainfall rates could hit 0.5 to 1 inches per hour, meaning debris flows and flash floods are very much a possibility.

• Wind: Should be around 20-30 mph, with gusts up to 73 mph in some spots. That's strong enough to potentially cause power outages and downed trees. Comparable to a strong Santa Ana wind event.
  
• Violent seas: South-facing beaches are particularly vulnerable and could see waves up to 10 feet high. There's also a high risk of rip currents. Boaters should seek safe harbor on Sunday and Monday due to dangerous conditions.

How emergency responders are preparing

State and federal officials from California Office of Emergency Services, Caltrans and other agencies provided updates on hurricane preparations on Saturday.

Their message for Southern Californians was clear: Stay off the roads during the peak hours of the storm between Sunday and Monday.

"If you must travel and you encounter water flowing across the roadways do not attempt to drive through it," said Tony Tavares, director of Caltrans, adding that the department may close roadways preemptively to ensure road safety.

Additional resources across the state have been summoned for support, including in emerency medical services and local sheltering operations.

And a number of military rescue vehicles are placed throughout the region.

"We also have other capabilities, soldiers, airmen who are standing by and will be prepared to respond as the need arises," said Colonel David Kauffman from the California Military Department.

On Saturday afternoon, the San Bernardino County Sheriff's office issued evacuation warnings for the communities of Oak Glen, Forest Falls, Mountain Home Village, Angelus Oaks, and Northeast Yucaipa.

As for the city of Los Angeles, it has issued an emergency alert and has activated its Emergency Operations Center, has a fully staffed fire department on standby and is expanding its 311 operating hours. The L.A. Department of Water and Power also has crews available to respond to power issues.

“Whether it be wildfires or earthquakes the city is prepared,” said Los Angeles Mayor Karen Bass during a news conference on Friday afternoon.

The L.A. County Department of Public Works has been clearing debris basins and culverts, and fixing roads across unincorporated areas since last spring, when the last of the atmospheric rivers slammed into us. They have teams ready to deploy in case of incident, as do Orange and Ventura counties.

"We're preparing for the worst, but the forecast is not out of line with what we were dealing with this last winter," said Steven Frasher, public information officer with L.A. public works.

Both L.A. and Ventura county fire departments are preparing for swift water rescues.

The city of Avalon on Catalina Island is expected to be one of the hardest hit spots. As such, L.A. County has preemptively deployed an additional rescue boat and personnel to the island.

The Los Angeles Sheriff Department is advising residents and tourists on Catalina to leave the island as soon as possible.

Some south and southeast facing beaches are being shored up in anticipation of a storm surge, including Seal Beach in Orange Count as it's particularly vulnerable. Long Beach, San Pedro, Point Mugu and Port Hueneme are as well.

What's the risk?

Heavy rainfall is likely to result in debris flows and flash floods. Desert communities out in places like the Antelope Valley could see flooded roads, especially at low water crossings.

Be smart and avoid driving Sunday night through Monday morning if you can. Treat this like you would a powerful atmospheric river.

The context

For the first time ever, the National Hurricane Center has issued a Tropical Storm Watch for areas across Southern California. The last time we were directly hit by a tropical storm was back in 1939, when one made landfall in Long Beach, according to the National Weather Service in Oxnard.

While the track of this storm is unusual, the hurricane itself is 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 impact Southern California. In September 2022, Hurricane Kay dropped more than 5 inches of rain on the area, causing flooding and damaging homes.

Cancellations

The Dodgers, Angels and Padres have all had their Sunday home games moved to Saturday, so they'll all be playing double headers.

Meanwhile, "CicLAvia—Koreatown meets Hollywood" has been canceled for Sunday. Organizers on Saturday announced that while the event "has always gone on rain or shine, the weather is just too unpredictable."

If you were planning on taking a trip out to the desert, you know that Joshua Tree National Park is closed to backpacking. And the Mojave National Preserve, which just saw its most destructive fire on record, is closed completely. It's unclear how this major storm is going to affect recovery efforts.

The Summer Sounds concert series in West Hollywood has been rescheduled.

The Interstellar Music Festival in San Pedro is canceled this weekend.

A number of Amtrak Pacific Surfliner trains between Los Angeles and San Diego are canceled Saturday night through Monday morning.

Downed tree, power line or flooded road?

Dial 911 if it's an emergency.

However, if you need to report a flooded road or a downed tree, you can call the following non-emergency numbers:

• L.A. City: Dial 311 for a flooded road or downed tree. Call (800) DIAL-DWP if you see a downed power line.
• L.A. County: (800) 675-HELP
• Ventura County: (805) 384-1500
• Orange County: (714) 955-0200 or visit here.

If you're in L.A. County and need sand bags you can find some at local fire houses.

As Los Angeles homeowners grapple with the expense of rebuilding after last year’s devastating fires, an L.A. City Councilmember is putting forward an idea that could lower some costs.

Councilmember Traci Park, who represents the Pacific Palisades, has introduced a motion to explore waiving part of the city’s portion of the local sales tax for fire victims who purchase rebuilding materials in the city.

The 1% of the local 9.75% sales tax that goes into the city’s general fund would be given back to consumers under the proposal. The waiver could apply to lumber, appliances and other rebuilding goods purchased within the city.

The motion, introduced Friday by Park and seconded by Councilmember John Lee, says: “The City should do everything within its power to alleviate the financial burden for these residents and businesses in order to facilitate their return and stabilize the Pacific Palisades community.”

Would it make much of a difference? 

Economists told LAist the proposal could help many homeowners mitigate the high cost of rebuilding, but likely wouldn’t tip the scales for under-insured, under-resourced property owners.

“It wouldn't hurt if it's very well designed and easy to use,” said Alexander Meeks, a director at the Santa Monica-based Milken Institute. “But I'm not sure if it's really going to tackle the scale of the financial challenge that survivors are facing.”

Meeks noted that the tax waiver wouldn’t lower up-front costs such as environmental testing, architectural design and permitting. And it may not help homeowners sourcing raw materials from outside the city.

Zhiyun Li, a UCLA Anderson School of Management economist, said the waiver could help some homeowners justify the additional cost of rebuilding more fire-safe structures.

“Homeowners must typically pay out of pocket to upgrade to IBHS+ standards, which are more stringent,” Li said. “The tax waiver could encourage upgrading to IBHS+ standards or investing more in mitigation, thereby reducing future risk and improving the likelihood of maintaining insurance coverage.”

What’s next for the proposal? 

The proposed tax relief would not be available to properties that have been sold since the fires started in January 2025.

The motion has been sent to the City Council’s budget and fire recovery committees. If approved by the full council, it would require the city administrative officer, the Office of Finance and the city attorney to report back to the council within 60 days on options for crafting a tax relief plan.

The motion calls for the report to consider factors such as how to minimize the burden of administering the tax relief, what documentation homeowners would have to submit and what it would cost the city to oversee the program.

Senate and House Republican leadership have resurrected a stalled plan to fund the Department of Homeland Security after a record 47-day funding lapse.

House Speaker Mike Johnson, R-La., and Senate Majority Leader John Thune, R-S.D., said in a joint statement on Wednesday that the House will take up a measure passed by the Senate last week to fund most of DHS except Immigration and Customs Enforcement and Border Patrol through the end of September.

Republicans would then attempt to fund ICE and Border Patrol for three years using a party-line budget reconciliation bill that would not require support from Democrats.

"In following this two-track approach, the Republican Congress will fully reopen the Department, make sure all federal workers are paid, and specifically fund immigration enforcement and border security for the next three years so that those law-enforcement activities can continue uninhibited," Thune and Johnson wrote.

The agreement comes nearly a week after House Republicans dismissed an identical plan, refusing to take up the Senate-passed measure and instead passing a 60-day short term funding bill for all of DHS that had little chance of overcoming Democratic opposition in the Senate.

Johnson called the agreement a "joke" and President Donald Trump declined to publicly endorse the deal. Trump had previously resisted any package that did not include his push to overhaul federal elections known as the Save America Act.

"I think any deal they make, I'm pretty much not happy with it," Trump told reporters last week.

Democrats welcomed the agreement as in line with their pledge not to give ICE any more money without reforms after immigration enforcement agents killed two U.S. citizens in Minneapolis. But the deal does not include any of the policy demands Democrats are pressing for, such as a ban on masks for immigration enforcement officers and requiring warrants issued by a judge, not just the agency, to enter homes.

"For days, Republican divisions derailed a bipartisan agreement, making American families pay the price for their dysfunction," Senate Minority Leader Chuck Schumer, D-N.Y., wrote in a statement Wednesday. "Throughout this fight, Senate Democrats never wavered."

Trump seemed to bless the revived plan earlier Wednesday, writing on social media that he wants a party-line bill to fund immigration enforcement on his desk by June 1.

"We are going to work as fast, and as focused, as possible to replenish funding for our Border and ICE Agents, and the Radical Left Democrats won't be able to stop us," Trump wrote.

Despite the shutdown, ICE has been minimally impacted because Republican lawmakers approved $75 billion for ICE through another party-line budget reconciliation bill last year.

Congress is on a two-week recess, but the Senate and House could move to fund all of DHS except ICE and CBP as early as Thursday using a procedure known as unanimous consent that allows the chambers to circumvent formal voting as long as no member objects.

Even during a recess when most members are not in Washington, this could be unpredictable, especially in the House, where many hard-line conservatives oppose a deal that does not fully fund DHS.

"Let's make this simple: caving to Democrats and not paying CBP and ICE is agreeing to defund Law Enforcement and leaving our borders wide open again," Rep. Scott Perry, R-Pa., a member of the ultra-conservative House Freedom Caucus, wrote on X. "If that's the vote, I'm a NO."

If a member does object, that could require waiting for another vote when all members are back from recess.

California clocked its second-worst snowpack on record Wednesday, a potentially troubling signal ahead for fire season.

It’s an alarming end to a winter that saw abnormally dry conditions briefly wiped from California’s drought map in January, for the first time in a quarter-century.

Though precipitation to date has been near average, much of it fell as rain rather than snow. Then March’s record-breaking heat melted most of the snow that remains. The state’s major reservoirs are nevertheless brimming above historic averages and are flirting with capacity, and a smattering of snow, rain and thunderstorms are dousing last month’s heat wave.

But experts now warn that California’s case of the missing snowpack could herald an early fire season in the mountains.

On Wednesday, state engineers conducting the symbolic April 1 snowpack measurement at Phillips Station south of Lake Tahoe found no measurable snow in patches of white dotting the grassy field.

“I want to welcome you call to probably one of the quickest snow surveys we’ve had — maybe one where people could actually use an umbrella,” joked Karla Nemeth, director of the California Department of Water Resources. “We’re getting a lot of questions about are we heading into a hydrologic drought? The answer is, I don’t know.”

State data reports that California’s snowpack is closing out the season at an alarming 18% of average statewide, and an even more abysmal 6% of average in the northern mountains that feed California’s major reservoirs.

Only the extreme drought year of 2015 beat this year’s snowpack for the worst on record, measuring in at just 5% of average on April 1st, when the snow historically is at its deepest.

“I think everyone's anticipating that it will be a long, busy fire season,” said Lenya Quinn-Davidson, director of the UC Division of Agriculture and Natural Resources Fire Network.

“Without a snowpack, and with an early spring, it just means that there’s much more time for something like that to happen.”

‘It’s pretty bizarre up here’ 

In the city of South Lake Tahoe, which survived the massive Caldor Fire in the fall of 2021 without losing any structures, fire chief Jim Drennan said his department is already ramping up prevention efforts.

“It's pretty bizarre up here right now. It really seems like June conditions more than March,” Drennan said. “People are already turning the sprinklers on for their lawns.”

Without more precipitation, an early spring may complicate prescribed burning efforts. But Drennan said fire agencies in the Tahoe basin can start mechanically clearing fuels from forest areas earlier than usual.

“That means we can get more work done,” he said.

It also means homeowners need to start hardening their homes now, said Martin Goldberg, battalion chief and fuels management officer for the Lake Valley Fire Protection District, which protects unincorporated communities in the Lake Tahoe Basin’s south shore.

Goldberg urges residents to scour their yards for burnable materials, create defensible space and reach out to local fire departments with questions. The risks are widespread — from firewood, wooden fences, gas cans, plants, pine needles — even lawn furniture stacked against a house.

“In years past, I wouldn't even think of raking and clearing until May,” Goldberg said. “But my yard's completely cleared of snowpack, and it has been for a couple weeks now.”

‘A haystack fire’

Battalion chief David Acuña, a spokesperson for Cal Fire, said fire season is shaped by more than just one year’s snowpack.

Climate change has been remaking California’s fire seasons into fire years. And California’s recent average to abundant water years have fueled what Acuña called “bumper crops of vegetation and brush.”

“Most of California is like a haystack. And if you’ve ever seen a haystack fire, they burn very intensely because there's layers of fuel,” Acuña said.

Like Quinn-Davidson, Acuña wasn’t ready to make specific predictions about fires to come.

But John Abatzoglou, a professor of climatology at UC Merced, said the temperatures and snowpack conditions this year offer a glimpse of California in the latter decades of this century, as fossil fuel use continues to drive global temperatures higher.

How this year’s fires will play out will depend on when, where and how wind, heat, fuel and ignitions combine. But it foreshadows the consequences of a warmer California for water and fire under climate change.

“This,” Abatzoglou said, “is yet another stress test for the future in the state.”
