TODAY
Personnel worked to build on existing containment lines, mop-up and monitor the perimeter of the fire before forecasted critical weather conditions take place early next week. Fire activity remained around the Mt. Lewis area where the fire has made its way down to the bottom of the drainage. Crews are looking at potential options to stop the forward rate of spread. Fire activity from Pinon Ridge to Dorr Canyon has moderated and crews will remain to patrol and mop-up the area. Most of the northern end and eastern end of the fire near Highway 39 to the San Gabriel Dam of the fire has seen minimal fire activity. Crews continued to monitor the area for heat signatures. Heavy mop-up to the north of Mt. Wilson to Highway 2 continued today. Aircraft and crews continued to battle isolated heat remaining near Chilao. To the south end, from Monrovia Canyon to Santa Anita Canyon, fire crews saw little to no heat signatures during mop-up.  A moderate Santa Ana wind event is forecasted for early next week. Fre crews will work to ensure priority areas remain ready.  Today, LA County Sheriff’s Department lifted evacuation warnings for selected areas in the Antelope Valley. Repopulation efforts continue with help from Los Angeles County Occupancy support. For more information visit: https://rb.gy/flykjl.


TONIGHT
Crews will continue to actively monitor and patrol containment lines in preparation for a rise in forecasted temperatures and increased winds, resulting in critical fire weather conditions. Night resources will be placed around the Mt. Lewis area and southeastern perimeter of the fire to monitor and hold existing lines. Additional night resources will be available as they continue mop-up and cold trailing on the north end of the fire.


WEATHER
Warm and very dry conditions with low humidity remained across the fire today. Tomorrow, building high pressure will bring warmer and drier conditions, as well as a shift to northeast ridgetop winds. Santa Ana conditions will bring stronger east to northeast winds beginning early Monday morning and lasting through the afternoon. These gusty winds will combine with very low humidity to produce a period of critical fire weather conditions. As a result, A Fire Weather Watch is in effect on Monday for gusty Santa Ana winds and low relative humidity.


EVACUATION ORDERS:
• Paradise Springs – South of Big Pines Highway, east of Devil’s Punchbowl, west of Largo Vista Road, and north of the forest.
• South and west of Upper Big Tujunga Canyon, east of Angeles Forest Highway, and north of Angeles Crest Highway.

Estimated Containment DateWednesday September 30th, 2020 approx. 12:00 PM

Chaparral, Brush, and Tall Grass

Significant Events

Mainly smoldering and creeping where heat exists within containment lines, should stay nearly within

existing footprint. A couple of exceptions: 1) in the northeast where the fire is backing, flanking and rolling out, with some flare ups; 2) is northwest of Mt. Wilson where interior island continues to consume with backing flanking, occasional flare ups/runs, and individual tree torching.

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

Main fire progression is in the northeast, heading in a northeast direction. Little growth expected, between

500-1000 acres to contingency line. A little movement is possible west of Waterman Mt.

Remarks

Containment dates are dependent on resource availability. Currently have limited resources for the fire. Critical need for resources continue. Damage Inspection Teams are assessing Juniper Hills and Valyermo areas.

Current Weather

Weather Concerns

Warm and very dry conditions occurred at the fire again today. Temperatures climbed into the 80s, and daytime humidity ranged from 15-35%. Ridgetop winds generally varied from the south to

west, with afternoon gusts into the 10-20 mph range.

On Sunday, building high pressure will bring warmer and drier conditions, as well as a shift to breezy northeast ridgetop winds.

Santa Ana conditions will bring stronger east to northeast winds beginning early Monday morning and lasting through the afternoon. These gusty winds will combine with very low humidity to produce a

period of critical fire weather conditions. As a result, A Fire Weather

Watch is in effect on Monday for gusty Santa Ana winds and low relative humidity. Near critical fire weather conditions are expected to continue each day through the remainder of the work week.
