Summary
Crews continue to battle the Mendocino Complex fire, which is burning in parts of Mendocino, Lake, Colusa, and Glenn counties in northern California. As of Aug. 27, the Ranch Fire - located north of Clear Lake - continues to grow northeast of Lake Pillsbury in Glenn County within Mendocino National Forest. The Ranch Fire has grown to 162,873 hectares (402,468 acres) and is estimated to be 67-percent contained. Authorities estimate full containment on or around Sept. 1. The much smaller River Fire, located south of the Ranch Fire, is 100-percent contained, having burned 19,797 hectares (48,920 acres).

The two fires combined constitute the largest wildfire in California's recorded history. Despite its size, though, the Mendocino Complex is largely burning in rural, forested areas; surveys indicate that 280 structures have been destroyed, while 38 others have sustained damage. An additional 1,050 structures remain threatened by the complex, and 3,000 personnel continue to battle the fire.

The authorities have lifted mandatory evacuations from Lake and Mendocino counties. The following evacuation orders remain in place for Colusa and Glenn counties:

  • Colusa County: Areas south of Colusa-Glenn County line; east of the Colusa-Lake County line; North of Goat Mountain Road extending to Sullivan Ridge and west of Mendocino National Forest boundary.
  • Glenn County: Areas north of Glenn-Colusa County line; east of Glenn-Lake County line; south of County Road 308 and Forest Route 24N02, and west of County Road 306.

Authorities in Lake County have maintained evacuation advisories for all areas previously under evacuation orders: Areas east of the Lake-Mendocino County line; south of the Lake-Mendocino-Glenn County line; west of the Lake-Colusa county line; north of the fire perimeter and the Mendocino National Forest boundary. In Colusa County, authorities issued evacuation advisories for all areas east of Mendocino National Forest's boundary and west of the East Park Reservoir, between Glenn County line and Lodoga; areas south of Goat Mountain Road extending to Sullivan Ridge east of Colusa-Lake County line and west of Mendocino National Forest's boundary.

Transport
The Mendocino Complex has caused localized transport disruptions in Lake, Mendocino, Glenn, and Colusa counties. As of Aug. 27, seven road closures remain in place in the affected communities. Low visibility from smoke and possible ashfall could contribute to traffic delays and congestion in the region.

Advice
Heed all evacuation orders. Seek updated information on road conditions if driving in the affected area; road closures and detours are likely. Individuals not under evacuation warnings should consider remaining inside well-ventilated, air-conditioned spaces to reduce exposure to smoke.

Summary
Two large wildfires burning in Lake and Mendocino counties continue to grow, with mandatory evacuation orders expanded in both counties. As of Aug. 4, the Ranch Fire - located near SR-20 - has burned roughly 63,405 hectares (156,678 acres), approximately doubling in size since Aug. 2, and is estimated to be roughly 27-percent contained. The River Fire, located just south of the Ranch Fire, has burned approximately 18,127 hectares (44,793 acres) and is 50-percent contained. 

Over 3,400 personnel are on site working to control the two fires, which are collectively known as the Mendocino Complex. The complex has destroyed at least 104 residential and non-residential structures; around 12,300 additional buildings in both counties are under threat. 

The authorities have issued the following mandatory evacuation orders, which will persist until firefighters increase containment percentages:

  • Lake County: For Lucerne, Pepperwood Grove, Paradise Valley, Glenhaven, and Clearlake Oaks areas of Lake County, all areas north of Clear Lake; Western Lake County, north of Clear Lake and Bartlett Springs Road, east of the Lake-Mendocino County Line, south of the Ranch Fire; Scotts Valley; Blue Lakes; Upper Lake; Bachelor Valley; Nice.

Emergency shelters are available for displaced residents at the Mendocino College, Lower Lake High School, Middletown High School, Twin Pines Casino, Middle Town Middle School and Mountain Vista Middle School.

Transport
The Mendocino Complex has caused localized transport disruptions in both Lake and Mendocino counties. As of Aug. 4, the following highway closures are ongoing:

  • SR-20: Closed from Potter Valley Road (Mendocino County) the Route 53 South junction (Lake County)
  • SR-29: From the Park Way Overpass (near North Lakeport) to the SR-20 junction

These highways serve as the main routes between the two counties; extensive delays are likely for local traffic. Additional road closures are also ongoing within the wildfire complexes and in the evacuated communities. Anticipate the status of highways and secondary roads to change in the coming days due to fire activity and the needs of response operations. Low visibility from smoke and possible ashfall could contribute to traffic delays and congestion in the region.

The Mendocino Complex is approximately 70 km (45 miles) north-northwest of Santa Rosa.

Advice
Heed all evacuation orders. Seek updated information on road conditions if driving in the affected area; road closures and detours are likely. Individuals not under evacuation warnings should consider remaining inside well-ventilated, air-conditioned spaces to reduce exposure to smoke.

As of Aug. 2, the Ranch Fire - located near SR-20 - has burned roughly 30,307 hectares (74,890 acres) and is estimated to be roughly 33-percent contained. The River Fire, located just south of the Ranch Fire, has burned approximately 14,277 hectares (35,278 acres) and is 50-percent contained. Over 3,000 personnel are on site working to control the two fires, which are collectively known as the Mendocino Complex. The complex has destroyed at least 38 residential and non-residential structures; over 12,000 additional buildings in both counties are threatened by the fires. 

Because of the size and expected growth of the Mendocino Complex, authorities have issued the following mandatory evacuation orders, which will persist until firefighters increase containment percentages:

  • Lake County: Areas north of the Lake/Sonoma County border, east of the Lake/Mendocino County border, south of the Ranch Fire, and west of Highland Springs, Big Valley, and Bartlett Springs roads; Lakeport; Scotts Valley; Blue Lakes; Upper Lake; Bachelor Valley; Nice
  • Mendocino County: Potter Valley; areas along SR-20

Emergency shelters are available for displaced residents at the Mendocino College, Lower Lake High School, Middletown High School, and Twin Pines Casino. 

Transport
The Mendocino Complex has caused localized transport disruptions in both Lake and Mendocino counties. As of Aug. 2, the following highway closures are ongoing:

  • SR-20: Closed from the SR-29 junction (Lake County) to east of the US 101 junction (Mendocino County)
  • SR-29: Closed from the SR-20 junction to Highland Springs Road (near Finley)
  • SR-175: Closed from east of the US 101 junction (Mendocino County) to the SR-29 junction (Lake County)

These highways serve as the main routes between the two counties; extensive delays are likely for local traffic. Additional road closures are also ongoing within the wildfire complexes and in the evacuated communities. Anticipate the status of highways and secondary roads to change in the coming days due to fire activity and the needs of response operations. Low visibility from smoke and possible ashfall could contribute to traffic delays and congestion in the region.

The Mendocino Complex is approximately 70 km (45 miles) north-northwest of Santa Rosa.

Advice
Heed all evacuation orders. Seek updated information on road conditions if driving in the affected area; road closures and detours are likely. Individuals not under evacuation warnings should consider remaining inside well-ventilated, air-conditioned spaces to reduce exposure to smoke.
