Route Fire Holding At About 5,200 Acres; Evacuations Lifted
This story will be updated as more information becomes available.
What We Know So Far
The Route Fire, which ignited just after noon Wednesday near the 5 Freeway in Castaic, has burned about 5,200 acres and is now 37% contained, fire officials reported Friday morning.
Their plan is to continue mopping up hot spots near containment lines, hoping to get the hardest work done before the midday heat.
Authorities say conditions remain challenging, with excessive heat, steep terrain and low humidity creating conditions that already injured seven firefighters on day one.
In a media briefing Thursday morning, Los Angeles County Fire Department Deputy Chief Thomas Ewald noted that containment is key, but can be difficult to report with certainty, as firefighters work to confirm that there's “no possibility of the fire jumping” containment lines.
“We can knock down the intensity of the fire, but it’s really about perimeter control."

The fire began just after noon on Wednesday at the I-5 and Lake Hughes Road.
- Cause is under investigation
- 550 structures threatened, 2 destroyed

As the predicted heat wave descended on the region, the district had already place the region under an ozone advisory, noting that "ozone air pollution can cause respiratory health problems, including trouble breathing, asthma attacks, and lung damage." The heavy smoke from the fire could exacerbate the risks.
Why It Matters
With high heat and low humidity expected for the next several days, any wildfire in the area is spreading quickly. At 4 p.m on the first day, the Route Fire was reported at 250 acres. By 5:30 it had grown to 600 acres, and less than two hours later it was at more than 4,600 acres and still spreading.
Emergency responders will be exposed to dangerous conditions. The National Weather Service reported temperatures near 110 degrees at the site of the fire shortly after the fire was first reported at 12:01 p.m.

The Context
California’s wildfires have gotten increasingly destructive and deadly.
Jacob Margolis, who covers fires for our newsroom, notes the Route Fire is burning in areas that appear not to have burned for decades.
"One spot hasn't burned since 1983 and other spots 2001 and other spots 2007. You know, all that's time for fuel to build up," said Margolis, who has an upcoming LAist Studios podcast on fires called The Big Burn.
Some important context to keep in mind from Margolis' larger explainer on wildfires:
Temperatures have gotten hotter and our landscapes have gotten drier, which makes them more susceptible to burning throughout more of the year. On top of that, extreme drought, of which climate change is a contributing factor, leads to plant stress and massive tree die off. Those dead trees become added fuel for fires.
