Mendocino Complex News Release — August 28, 2018

Mendocino Complex Wildfire
News – 8/28/2018

WILLOWS, Calif. — The Mendocino Complex is being managed by the United States Department of Agriculture Forest Service and CAL FIRE under a unified command. California Interagency Incident Management Team 3 is managing the western zone of the Ranch Fire. CAL FIRE Team 2 is managing the eastern zone of the Ranch Fire. The fires of the complex are located on the Mendocino National Forest and CAL FIRE Mendocino, Sonoma-Lake-Napa and Tehama-Glenn Units.

With firing operations complete the fire is no longer a threat to state land. On Wednesday, August 29th, CAL FIRE Team 2 will hand off the East Zone of the fire to California Interagency Incident Management Team 3. Team 3 will manage the East and West Zones of the Mendocino Complex.

Ranch Fire:

A short change in the weather pattern is expected to push smoke from the fire toward the west today. This change will bring higher wind speeds, warmer temperatures and lower relative humidity to the fire area. These conditions are expected to cause more active burning in islands of vegetation within the fire perimeter. The fire size increased by 7,714 acres (primarily due to mapping changes eliminating a large interior island) in the last twenty-four hours with the fire now estimated at 459,102 acres and 90 percent contained. Currently there are 2,440 personnel assigned to the Ranch Fire.

In the East Zone firing operations have been completed and operations are focused on mopping up heat found near the fireline. Crews have mopped in 150 feet from the edge of the line and will be improving that effort today. Large interior stands of fuel are expected to produce smoke as they burn off.

In West Zone a change in wind direction and velocity will test fireline in the area of Little Round Mountain and Bloody Rock on Tuesday. Firefighters will be watching closely as easterly winds push toward the ridge at up to 25 mph. The fire in this area has burned down to the Eel River and Anderson Creek drainage and is not expected to escape current lines. Suppression repair activities include chipping cut fuels, water bar construction, deconstruction of berms and pulling cut materials back across the line.

River Fire: The River fire remains at 48,920 acres and is 100 percent contained. Management of the River Fire has been returned to the Mendocino Unit of Cal Fire.

Smoke: Easterly winds today will drift smoke and haze from the Ranch fire to the west and over the coast. Local communities such as Covelo, Potter Valley and Laytonville are expected to see the highest impacts with moderate to heavy smoke increasing through the day. Ukiah and areas closer to the coast should see hazy skies and moderate smoke impacts. To the east of the fire, in the Sacramento Valley, including Elk Creek, Stonyford and the Clear Lake region, markedly improving air quality is expected by midday. Tomorrow, a return to light and variable winds will allow lingering smoke to sink into local communities on all sides of the fire.
