Firefighters in California are working tirelessly, battling several major blazes across the state, as wildfire season rages on. Cal Fire has urged Californians to be "extremely cautious" and asked that residents and visitors take measures to prevent any more blazes.

Mendocino Complex Fire
Ukiah and Hopland, California
302,086 acres, 47 percent contained

The Mendocino Complex Fire is actually comprised of two major fires. The Ranch fire, which ignited on July 27, near Ukiah, California, has burned through 253,166 acres and is 46 percent contained, according to an update by Cal Fire on Wednesday. Meanwhile, the River fire in Hopland, California, has reached 48,920 acres and is 81 percent contained.

In total, the two fires have burned through 302,086 acres and are just 47 percent contained. According to Cal Fire, the blaze is expected to be fully contained by September 1. At least 9,200 structures are under threat by the fire, which has already destroyed 229 structures and damaged 27 others.

Cal Fire said crews "were successful eliminating potential fire and decreasing spotting potential in the southern section" of the Ranch fire. "The River Fire saw no growth and crews continued to patrol the fire boundary," Cal Fire added.

Mandatory evacuations remain in parts of Lake County, Mendocino County and Colusa County. Parts of Mendocino County, Glenn County and Lake County are also under an evacuation advisory.

There are 4,019 fire personnel working on the Mendocino Complex Fire. Crews are being supported by 404 engines, 93 water tenders, 19 helicopters, 64 hand crews and 84 dozers. Two firefighters have been injured by the fire.

Cal Fire said that the wildfire is located "in steep drainages with varying wind exposure. Timber fuels have challenged firefighting efforts." Fire crews are focused on constructing containment lines and dealing with spot fires across control lines.

More than 1,000 residential structures were destroyed, and another 191 residences were damaged by the Carr fire. Meanwhile, 22 commercial structures and 500 other structures have been destroyed. At least 26 commercial structures and 65 other structures were damaged.
