Today’s priorities for work on the Bobcat Fire are to continue work on the control lines. These lines are being built in the northeastern and northwestern portions of the fire in order to stop the forward progression. Additionally, firefighters will continue to mop up and secure the areas around structures where the fire burned into Antelope Valley and Juniper Hills. We will also be looking for ways to secure the line between Mt. Wilson and Highway 2 to eliminate the threat to that area. Residents are urged to remain alert for any additional evacuation orders or warnings that may be issued. For information on evacuations follow LA County Sheriff’s Dept. Twitter at @LASDHQ or https://bit.ly/35Uy9Ld


Additional evacuations were ordered for residents in the Antelope Valley yesterday. Yesterday and into the night the fire remained active due to windy conditions, especially on the north end. Over the evening the fire did moderate some and work started on direct lines. Successful strategic firing occurred to secure the area around Mt. Wilson last night. Aside from Mt. Wilson, the fire remained quiet from Crystal Lake all the way around the south end back up to Highway 2.


The weather today will me mostly clear with areas of smoke and temperatures will be steady throughout the day. Humidity will drop into the teens again and winds will remain southerly, with the strongest winds occurring in the northern portion of the fire again. A warming and drying trend is expected for mid-week.

West Fork of San Gabriel Canyon at Cogswell Dam
Incident Commander:
Angeles National Forest
Incident Description:

Current Situation

Total Personnel:
Size (Acres):
Estimated Containment Date:
Friday October 30th, 2020 approx. 12:00 PM
Fuels Involved:
Chaparral, Brush, and Tall Grass
Significant Events:
The Bobcat fire remained active overnight due to poor humidity recovery. Flanking continued in the Mt Wilson area and toward the northern part of the Bobcat Fire. Spotting continues to present challenges.

Planned Outlook

Planned Actions:
Continue direct and indirect line construction with resources available utilizing pre existing dozer lines when possible. Provide structure protection when fire impacts communities.
Projected Incident Activity:
Fire will continue to spread from the foothills into communities of Juniper Hills, Valyermo and Big Pine. Wind-driven fire spread downslope with spotting and rapid growth threatening structures. Community of Littlerock and Wrightwood will be impacted soon. On the east side, fire continues to threaten containment lines north of the Ranch 2 fire and threatens the Hwy 39 corridor. Very poor humidity recovery, especially in higher elevation, and warm overnight temperatures will allow the fire to burn actively through the night. Fire activity on the eastside
of Mt. Wilson Observatory is threatening all of the values on that peak
Containment dates are dependent on resource availability. Currently have limited resources for the fire. Critical need for resources continue.

Weather Synopsis

Weather Concerns:
Slightly cooler temperatures were observed today. Humidity
exhibited moderate recovery this morning, before dropping into the 15-25% range this afternoon. Gusty southwesterly/upcanyon winds
prevailed through the afternoon. Wind speeds, albeit lower than Friday, were still gusting between 20 and 30 MPH in the windier spots.

For tonight and Sunday, little change in temperatures is expected. However, some drier air will move into the area. This will result in poorer humidity recovery tonight and lower relative humidity on Sunday. Weak southerly/downcanyon winds will prevail tonight with southwesterly/upcanyon winds on Sunday. After similar
conditions on Monday, a warming and drying trend is expected midweek.
