The fire remained active overnight. RH recovery moderated fire behavior some, however large diameter dead and downed fuels will continued to smolder and burn down. Scattered heat is detected near control lines, posing a threat. Fuel moistures remain critically low for both live and dead fuels. SW winds are forecasted through the weekend into next week. SW winds are associated with large fire growth. The Energy Release Component is above the 97th percentile. The Burning Index is above the 90th percentile. Potential exists for wind driven surface fire due to alignment.

WEST ZONE: Provide for the life safety of citizens and emergency responders. Implement structure and critical infrastructure defense. Construct control lines and take advantage of targets of opportunity as allowed by fire behavior and resource availability. Improve and hold established control lines. Hazard mitigation will remain ongoing in communities to "make safe" for repopulation. Aggressive mop up and tactical patrol of perimeter contained.

Aggressive mop-up, backhaul of hose, and tactical patrol will continue in Branch 1 and 30. In DIV N and P, crews will continue to strengthen and improve control lines, and provide structure defense in communities in the Kirkwood area. Direct line construction will continue in DIV I. MIST tactics will be used in the Desolation Wilderness. Fire Suppression Repair continues to evaluate repair needs and will implement the Incident's Fire Suppression Repair Plan.

EAST ZONE:

From Highway 89 west to Scout Peak, crews will remain engaged in strengthening direct containment lines with mop up to reduce the threat to structures. In the Christmas Valley area, resources will continue to patrol and mop up as necessary.

On the northeastern side of the fire, resources will strengthen existing fireline and continue to use direct

tactics.

On the southern flank of the eastern finger of the fire, a combination of direct hand and dozer line has been completed to keep fire from moving to the south and east.

Crews will continue to mop up and secure the line.

In the northwest part of the zone, west of Upper and Lower Echo lakes, crews will continue to construct direct fireline toward Pyramid Peak.

In the Lower and Upper Echo Lake areas, mop up and patrol continues.

Crews patrolled the fireline area to the southwest in the Scout Peak area. Direct line construction continues to the southwest.

Crews are constructing direct line to the east and to the west from the DP 68, in the Strawberry Creek area.

In the Caples Lake area crews will hold line, mop up, and extend fireline past the zone break.

A contingency group is nearing completion on building contingency lines to the northeast of the fire in the event of fire crossing primary containment lines.
