The Bobcat Fire has been burning in the Angeles National Forest now for more a week. Crews are hoping to take advantage of low winds forecasted for the next few days to draw some containment around the flames and protect nearby foothill communities under evacuation warnings.

Overnight, fire officials said low humidity kept the fire active, with most growth on the north and south fronts.

Officials are particularly concerned about the community of Monrovia, where the city is asking residents to help firefighting efforts by conserving water. At approximately 4:30 p.m. on Saturday, the fire reached the Trask Boy Scout camp and Canyon Park.

Half an hour later, the fire also spread into Big Santa Anita canyon near Chantry Flat.

Fire officials today said they're trying to hold the fire north of Highway 39 and strengthen the containment lines they've created to keep the fire out of foothill communities to the south.

The good news? The western and some of the eastern front of the fire are heading toward areas that have previously burned in this year's Ranch 2 Fire, 2016's Fish Fire and the 2009 Station Fire. That means there's less fuel.

The bad news? The north and other parts of the east fronts are heading toward areas that haven't burned in 80 years.

Here's what we know so far today:


  • Acreage: 29,245 acres
  • Containment: 6%
  • Resources Deployed: 765 personnel

The brush fire erupted near the Cogswell Dam and then spread rapidly amid an intense, record-breaking heat wave, prompting evacuation orders for Mt. Wilson Observatory. The cause is under investigation.

  • The Angeles National Forest — along with every other national forest in the state — has been closed
  • State Route 39 is closed at Old Gabriel Canyon Road
  • State Route 2 east of Upper Big Tujunga Canyon Road to Islip Saddle
  • Upper Big Tujunga Canyon Road
  • Mt. Wilson Road


Evacuation warnings currently include residents living in the following foothill cities and communities:

  • Duarte
  • Bradbury
  • Monrovia (for residents north of Foothill Boulevard)
  • Sierra Madre (residents can call 626-355-1414 to learn more about impacted areas)
  • Pasadena
  • Altadena

"Residents should have evacuation plans in place, organize their emergency evacuation supplies, and have essential evacuation personal belongings easily accessible," U.S. Forest Service officials wrote on the fire incident page. "Vehicles should be fully fueled, facing out in their driveways and ready to leave. Please make those arrangements now."

According to L.A. County officials, a shelter area for horses has been established at the Pomona Fairplex (entrance at Gate 12).

An evacuation site at Santa Anita Park was closed Thursday, according to the local chapter of the American Red Cross.


Expect higher than normal temperatures through the weekend, but nothing like we experienced last Sunday.

Smoke advisories are now in place through at least Sunday. Smoke blanketed much of the L.A. basin this week, bringing unhealthy air quality with it.

And what's up with that orange glow we've been seeing in SoCal skies? According to Phillip Fine, deputy executive officer for planning and rules with South Coast Air Quality Management District, that's largely due to the massive wildfires burning in Northern California and Oregon. Those blazes have created a smoke plume that's almost 1,000 miles wide, Fine said, but local air quality hasn't been as affected, he explained.

"A lot of that smoke is not making it down to ground level, thankfully, but that's why all over Southern California, we're seeing this eerie, orange glow... If you look at the air quality that they're experiencing up in Northern California and Oregon, it is much worse [than what] we're getting in Southern California and much more widespread, so we're somewhat fortunate we're not seeing those level of impact."

Our orange-tinged skies pale in comparison to the absolutely apocalyptic color pallete people in the Bay Area have experienced this week.

The poor air quality is also affecting COVID-19 testing in L.A. County. Officials announced today that several testing sites will be closed through the weekend due to the unhealthy air. The list includes:

  • College of the Canyons
  • East LA College
  • Pomona Fairplex Gate 17
  • San Gabriel Valley Airport
  • Montebello Civic Center
  • Panorama City


The Mount Wilson Observatory houses 18 telescopes, many of which were used to make some of the greatest astronomical discoveries of the last century.

They include the 100 inch Hooker telescope that Edwin Hubble used in the 1920s to prove that our universe is still expanding.

Observatory Director Tom Meneghini said he's afraid they could be seriously impacted if the fire gets close enough.

“The heat can do irreparable damage. Our two big telescopes are historically significant and irreplaceable,” Meneghini said.

However, he said fires have gotten close before and the decades-old firefighting setup at the Observatory is ready to be used again.

"We have an inground system of hoses and pumps," he said. "We have half a million gallons of water ready to pump so that’s all been prepared for any fire professional to come in and take over."

The fire also threatens a seismic station that has recorded earthquake activity for 100 years, seismologist Lucy Jones said via Twitter.

Numerous television and radio stations have transmitters in the area, including our newsroom which broadcasts on the radio at 89.3 KPCC.
