Topline:
With just a handful of narrow roads to evacuate thousands of residents, a fast-moving wildfire could be a nightmare scenario in Topanga Canyon.
What we know: If it’s hot, dry and windy enough, a wildfire could potentially burn from the San Fernando Valley to the Pacific Ocean in four hours.
Be prepared: If you’re in any fire prone area, pack a go bag, back your car into your driveway and make sure that you sign up for emergency messages, which is how the fire department will tell you what to do.
If a red flag is announced: Consider leaving in advance before evacuation orders are given so that you don’t get stuck in traffic.

Topanga Canyon’s nightmare fire scenario begins in the middle of the night when everyone’s asleep at home.
As blustery Santa Ana winds blow in from the east, a spark from a powerline or a passing car drops onto dry brush, starting a fire along the edge of the San Fernando Valley. As the flames grow, emergency services send out alerts, waking up thousands of residents throughout the area, telling some to shelter in place and others to leave.
It’s an increasingly likely situation as our vegetation dries out and winds pick up, according to Drew Smith, fire behavior analyst with L.A. County Fire.
“I would not be surprised,” Smith told me as we stood atop a helipad looking across the Transverse Ranges. “We are training for that.”
With only a few arteries in and out of the canyon, Smith warns that a fast-moving wildfire could trap people on the canyon’s narrow roads, consuming everything in its path.
In a worst-case scenario, the fire explodes into a devastating tragedy akin to the 2018 Camp Fire in Butte County, which destroyed the town of Paradise, trapping people trying to escape. At least 85 people were killed.
“That’s one thing that keeps me up at night,” he said. “That worst-case scenario fire with our residents at home with limited options. It’s terrifying.”
Preparing for the worst-case scenario

It’s difficult to emphasize just how dangerous wind driven fires can be, especially where we were standing, near the top of Stunt Road, above Calabasas.
Looking out across the Santa Monica Mountains, you can see small communities tucked in between dense chaparral that hasn’t burned in 30 plus years. Meaning, there’s a whole lot energy ready to fuel fires that roll through.
If the Santa Ana winds are blowing, strong gusts can throw embers more than a mile ahead of a fire front, starting up spot fires all over.
And because of the steep and rocky terrain, firefighting hand crews and bulldozers might struggle to dig fire lines meant to help contain the fire.
Even with water drops from helicopters, containing a fire in nightmarish fall conditions can be all but impossible.
“We know that fire history tells us on a high risk day, if we don’t suppress a fire within the first 10 minutes, it has a high probability of extending to the Pacific,” Smith said.

Smith estimates that it'd take one of these worst case scenario fires about four hours to sweep westward, from the San Fernando Valley to the Pacific Ocean, destroying communities along the way. Just as we saw during the Woolsey Fire in 2018, which made its way 17 miles across L.A. to Malibu in less than 24 hours, destroying 1,600 structures and killing killing three.
"Don't get lured into a false sense of security because we've had a very passive fire season in Los Angeles County," said Smith. "Under the right conditions, we have a high potential for a devastating fire in the Santa Monica Mountains that hasn't seen fire frequency in 25 years."
Topanga isn't the sole community at risk, the threat really applies to those throughout the Santa Monicas.
A key staging area: 69 Bravo
The helipad Smith and I were standing on is called 69 Bravo, and it’ll likely be one of the most important staging areas for firefighters when one of these fires does break out.
It sits at about 2,600 feet above sea level, offering views of Newhall Pass on one side and the Pacific on the other. Below the pads are four 8,000 gallon water tanks that automatically refill, there to be drawn on by helicopters and fire trucks that are working to head off flames on their run to the ocean.

The four, 8,000 gallon tanks at 69 Bravo have open tops so that firetrucks and helicopters can draw directly from them. They automatically refill.
How do you know if conditions are ripe for an extreme fire?
It’s quite likely that many fires will be started – all by people – in the coming months. Though, each won’t become a Woolsey level event.
So how do you know if you should be worried?
Smith laid out some of the key conditions he looks for to figure out if a fire is going to move fast:
Temperatures above 80 degrees
Relative humidities in the single digits
Live plants with moisture levels at 80% or less (they’re usually around 55% by the fall)
Strong, gusty winds
If you want to keep it simple, look out for red flag warnings from the National Weather Service, which indicate that extreme fire behavior is possible.
Check out their Fire Weather Snooper, which presents data from weather stations that are entering or in red flag territory.
On average we get eight red flag events per year, according to Smith, and on average each lasts three days.
How you can prepare and respond
Red flag warning prep
It’s always a good time to prep for disasters, especially before a red flag event arrives:
If you live in a high risk area like Topanga Canyon and a red flag event is on its way:
How to stay safe in high-risk areas
Back your car into your driveway and have your go bag in the car, ready to leave at a moment’s notice
If you get an emergency alert, follow the instructions given by emergency services. They’ll be coordinating evacuations, and will make efforts to keep roads from getting clogged
Consider leaving long before any fire breaks out. Smith said he knows people in Topanga that leave as soon as a red flag event starts

CLEAN is a rapid response soil testing program from the USC Department of Earth Sciences and Public Exchange developed by USC faculty, students and staff to assist local communities impacted by fires in L.A. County.
Residents can collect soil samples and drop them off at Boyle Heights City Hall for CLEAN to collect.
Submit this survey– Your sample ID will be provided upon completing the survey. Make sure to save your ID as this is how the CLEAN team keeps track of your sample and provides results to you.
Before getting started, gather your materials and protective equipment. (ADD points)
Disposable gloves and an N95 or KN95 facemask
Plastic spoon or shovel
Ziploc bags (2 per composite samples)
Permanent marker
Masking tape (for bag label)
9-digit sample ID code (from your survey)
Select your sampling zones
Your sampling zones are where you will be collecting the soil from. Your zones can be your front or back yard, garden, etc. The picture on page four of the guide shows the different zones in a home and though your home may not have all zones, what’s important is that you understand what zones you’re collecting from and labeling them accordingly.
Once you’re wearing your protective gear and have your equipment, you are now ready to collect the sample.
Collect two spoonfuls of soil for 2-5 different spots within a single zone
Drop all spoonfuls from the zone into one Ziploc bag. By the end of collecting, the bag should have about a cup size of soil in it.
Seal your Ziploc bag and for extra protection, put it over another Ziploc bag. This bag will now contain the zone’s composite sample.
Then repeat for every other zone you want to test. You should have one composite sample per zone you test. (e.g. one for the garden, one for the front yard, etc.)
Using a permanent marker, label each Ziploc bag with your unique sample ID and the zone name either on tape or directly on the bag.
Then you repeat steps 5 and 6 for each zone you are testing.
After collection
Once you have finished collecting your samples, make sure to wash your hands. If you suspect your soil to be contaminated, CLEAN suggests limiting access to that area, wiping or taking shoes off before entering your home, and preventing children from playing in bare soil.
CLEAN will test all samples for lead and some select samples will be tested for Arsenic, Chromium(VI), and Mercury. Testing for lead can take up to four weeks, while tests for other materials may take longer.
Where to submit your sample
After collecting and labeling your soil samples, you can submit them using one of the following methods:
Option 1: Drop Off Your Sample
Boyle Heights City Hall Address: 2130 E. 1st Street, Los Angeles, CA 90033 Hours: Monday–Friday, 9 a.m.–5 p.m.
Option 2: Mail Your Sample
CLEAN Project Address: 3651 Trousdale Parkway, USC ZHS 117B, Los Angeles, CA 90089

A Los Angeles Superior Court judge ruled Tuesday that the city of Inglewood can, for now, continue its deal allowing WOW Media to run its digital billboards along the city’s major roads.
The backstory: Last summer, companies tied to SoFi Stadium, Kia Forum and Intuit Dome sued to block the agreement, arguing that the city had violated competitive bidding rules and policies governing the use of public roads and sidewalks.
More details: Superior Court Judge Joseph Lipner rejected several claims brought by the stadiums, saying in a 25-page ruling that WOW’s agreement with the city adhered to rules governing the public right–of-way, the legal term for publicly accessible roads, sidewalks and other paths.
Inglewood’s video billboards just secured a big legal victory.
A Los Angeles Superior Court judge ruled Tuesday that the city of Inglewood can, for now, continue its deal allowing WOW Media to run its digital billboards along the city’s major roads.
Last summer, companies tied to SoFi Stadium, Kia Forum and Intuit Dome sued to block the agreement, arguing that the city had violated competitive bidding rules and policies governing the use of public roads and sidewalks.
The stadiums, which run their own massive digital billboards on its properties, also claimed the city’s dealings with WOW breached their contracts with the city. Court records previously reviewed by The LA Local suggested the yearslong relationship between Mayor James Butts and SoFi Stadium owner Stan Kroenke was fraying.
At one point, Butts claimed the city’s SoFi Stadium development agreement was void.
The dispute also moved beyond the courts and onto the streets when stadiums launched a ballot initiative aimed at banning WOW’s billboards. WOW fired back with a pair of its own ballot initiatives aimed at stadium taxes and parking fees.
Superior Court Judge Joseph Lipner rejected several claims brought by the stadiums, saying in a 25-page ruling that WOW’s agreement with the city adhered to rules governing the public right–of-way, the legal term for publicly accessible roads, sidewalks and other paths.
The judge also ruled that the city was not required to open a competitive bidding process for the agreement because WOW and its patented spiral video kiosks were uniquely positioned to fulfill the contract.
But Lipner said he did not have jurisdiction to rule on allegations by the Forum and Intuit Dome that the city breached their development contracts.

Butts told The LA Local that the court’s findings speak for themselves and touted the revenue the billboards bring the city. Inglewood has made as much as $7.4 million in billboard revenue in a year, according to budget documents.
WOW celebrated Lipner’s ruling in a statement to The LA Local, calling the stadiums’ court case and ballot initiative part of an “expensive misinformation campaign.”
“The court’s ruling makes clear that the city followed the law and acted in the best interests of its residents,” WOW CEO Scott Krantz said. “It has become abundantly clear that the stadium duopolists want complete control of every facet of Inglewood life.”
A spokesperson for Hollywood Park, the complex that includes SoFi Stadium, said it plans to appeal and that the case raised important questions.
“We respectfully disagree with the court’s decision regarding the city’s long-term agreement with WOW and continue to believe that leasing public rights-of-way in this manner is inconsistent with state and municipal law,” the spokesperson wrote.
Beyond a possible appeal by the stadiums, Lipner wrote that the parts of the case he did not rule on will be transferred to another court department to be calendared for future proceedings.

A judge declared a mistrial on Friday for a former Pacific Palisades resident accused of starting a fire that led to last year’s destructive Palisades Fire after the jury said it was deadlocked after about two days of deliberations.
Why it matters: The Palisades Fire in 2025 burned for more than three weeks across 23,000 acres. It killed 12 people, destroyed homes, businesses and displaced thousands of residents, some of whom still haven’t been able to return to their neighborhoods more than a year later.
The backstory: Firefighters initially kept the Lachman Fire contained to about 8 acres, but it continued to burn underground in the days following. A strong, widespread windstorm spread the remnants to the surface and into nearby communities, becoming the Palisades Fire on Jan. 7.
Read on... for more on the case, how we got here and what's next.
A judge declared a mistrial on Friday for a former Pacific Palisades resident accused of starting a fire that led to last year’s destructive Palisades Fire after the jury said it was deadlocked.
Jonathan Rinderknecht, 30, was facing up to 45 years in federal prison for one count of destruction of property by means of fire, one count of arson affecting property used in interstate commerce and one count of timber set afire.
The judge set a new trial date for Oct. 19 and the court ordered Rinderknecht remain detained.
Assistant U.S. Attorney Bill Essayli said on social media that the evidence against Rinderknecht is "strong."
"We fully intend to retry this case before a new jury and obtain guilty verdicts on all charged counts," Essayli said.
It was announced Thursday that the jury had reached a verdict, but when attorneys and Rinderknecht filed into the room, the judge said the opposite — the jury cannot make a unanimous decision on each of the three charges based on a note they shared with the court.
The jury exchanged further notes with the judge that said there is nothing the court could do to help them reach a unanimous verdict and there were jurors dead set on both sides.
What happened in court?
The trial reconvened Friday to figure out the next steps after the jury said it was deadlocked.
Prosecutors were pushing for the court to tell the jurors to go back to deliberations in an attempt to work it out, but U.S. District Judge Anne Hwang expressed concerns that it could come off as coercion.
Hwang decided to call the jurors into the courtroom to confirm they cannot reach a unanimous verdict, and that there is nothing else the court could do to help them. All 12 members confirmed that was the case and said the split was 10 not guilty and two guilty.
Prosecutors argued that Rinderknecht maliciously started a smaller fire — the Lachman Fire — near a hiking trail in the Santa Monica Mountains just after midnight on New Year’s Day 2025. About a week later, it became the Palisades Fire, one of the most destructive wildfires in California history. It killed 12 people and destroyed thousands of structures.
How we got here
Firefighters initially kept the Lachman Fire contained to about 8 acres, but it continued to burn underground in the days following. A strong, widespread windstorm spread the remnants to the surface and into nearby communities, becoming the Palisades Fire on Jan. 7.
According to thecriminal complaint, Rinderknecht was working as an Uber driver on New Year’s Eve and dropped a passenger off in the Pacific Palisades before walking up the trail about a block from his former home. Two passengers later described Rinderknecht as appearing angry and agitated that night.
He took two phone videos from a hilltop clearing about half an hour before the first signs of the Lachman Fire were spotted in the area. According to prosecutors, Rinderknecht unsuccessfully tried to call 911 several times in the following minutes, eventually reporting the fire when he got through to authorities toward the bottom of the trail.

Cameras captured Rinderknecht driving away from the area before turning around and following fire trucks to the scene, according to the complaint. Prosecutors said he then hiked back up the same trail to take phone videos of the fire and first responders.
Officials later said the Palisades Fire was a “holdover” fire, a continuation of the smaller Lachman Fire from six days prior.
The Palisades Fire burned for more than three weeks across 23,000 acres. It destroyed homes, businesses and displaced thousands of residents, some of whom still haven’t been able to return to their neighborhoods more than a year later.
Steve Haney, his defense attorney, has said prosecutors are trying to blame Rinderknecht for a fire that started nearly a week before.
"Well what about what happened between Jan. 1 and Jan. 7?" Haney told reporters last fall. "Jonathan wasn't out there with a fire hose putting that fire out at the Lachman location, the Fire Department was. So why are they blaming him for whatever the Fire Department didn't do?"
Haney said during the trial that “no matter what the government's theory is, the evidence will show Jonathan did not start the Jan. 1 fire," according to LAist’s media partner CBS LA.
Moving forward
According to the Los Angeles Fire Department’s after action report, staffing levels on the day the Palisades Fire started fell short of the standard for extreme weather conditions. Despite the high risk, the report said the decision not to deploy more firefighters in advance was made in part to save money.
Los Angeles Fire Chief Jaime Moore, who was tapped for the top job after the former chief was removed by L.A. Mayor Karen Bass citing the fire response, said things have changed since then.
Moore told LAist’s AirTalk in January that the department has updated its policies to increase staffing for especially hazardous conditions and promoted training in wildland firefighting, which have different challenges than those in urban environments and contributed to confusion during the Palisades Fire.
