August Complex North Zone Fire Update

September 23, 2020

Incident Commander: Norm McDonald

Start Date: 08/17/2020           Location: Shasta-Trinity NF; Six Rivers NF; Mendocino NF

Cause: Lightning                                    Fire Size: 859,966 (All Zones)

Containment: 39%                               Personnel (North Zone): 788

(Redding, CA) – Critical fire weather is expected today and Thursday as a trough of low pressure moves through the area. Winds out of the southwest at 10-20 mph are expected to clear the air on the western portion of the fire, and aid firefighters working around and north of Ruth. Helicopters and airtankers will be working today as the inversion lifts this morning. These winds, gusting to 25 mph on the ridges, will also challenge containment lines on the north and west perimeter. Spotting up to 1 mile ahead of the fire is possible.

The “surge resources," Type 2IA fire crews on loan from other fires, are working day and night to strengthen the dozer lines south of Highway 36, handline down from Rattlesnake Ridge, and contingency dozer line along the 29 Road to the east of the fire. The North Structure Group continues to work to improve access in Post Mountain/Trinity Pines, and widen the existing fuel break that the Forest Service has built surrounding the community. Dozer lines are nearly complete to the south and west of these communities.

“What we’d like to do is keep that fire south of Highway 36 and keep that highway open,” said Incident Commander Norm McDonald. “But I think one thing we’ve got to get across is that it’s going to be a tough order, considering the fire behavior that we have and the weather conditions that we having coming over the next few days.”

Yesterday, improved air quality allowed helicopters and airtankers to assist crews working on the ground above Ruth. Heavy equipment bosses are working with dozer crews to cut two lines above Ruth Lake. Strategic firing operations are also being used while winds and weather are favorable to strengthen these lines and protect the homes and businesses there. Structure assessment and protection is ongoing in the area.

The winds that cleared the air in Ruth and Forest Glen are bringing increased smoke to the communities to the north and east of the fire. Air quality is expected to remain poor in Post Mountain, Trinity Pines and Hayfork through Thursday evening, when winds are expected to shift again to the northwest. 

Although resources are limited, engines crews continue to patrol and mop up portions of the perimeter on the east and west portions of the North Zone. This includes the control lines south of Ruth and in the west near Yolla Bolly.
