Photos: Carr Fire destroys over 800 homes in Redding, California; Mendocino Complex fires threaten over 10,000 homes

Minimal relief is on the way for California firefighters battling several massive wildfires that have set large swaths of the state ablaze.

As of Tuesday morning, the deadly Carr Fire in Shasta County had burned nearly 110,000 acres and was 27 percent contained. It first ignited July 23 following the mechanical failure of a vehicle.

Six people have died in the fire, including two firefighters.

The blaze has destroyed 818 residential structures while damaging nearly 170, according to Cal Fire. Sections of several neighborhoods in the city of Redding were completely lost. Over 4,000 structures remain threatened.

It is currently the ninth-most destructive wildfire in California history.

Firefighters have made up some ground on the blaze in the last several days, but persistent hot, dry and windy weather will pose challenges.

High temperatures in the region will not reach as high as 110 degrees Fahrenheit as they did last week but will still be over 100 F through Friday in Redding, according to AccuWeather Meteorologist Evan Duffey.

"Over the weekend, a storm system coming onshore in the West will bring temperatures down into the 90s and bring a slight uptick of humidity, but there is no rain expected," Duffey said.

The wind will be generally light, between 4 and 8 mph out of the south the next couple of days around Redding, according to Duffey. Duffey, who is also a volunteer firefighter, said the weather through the rest of the week won't be ideal for firefighter, but it will be better than it has been.

Evacuation orders have been lifted for Douglas City and portions of Happy Valley, Shasta Lake City and Redding, officials said.

Farther south in Mendocino County, the River Fire and Ranch Fire were combined into the Mendocino Complex. Both blazes are threatening more than 10,200 residents in Lake and Mendocino counties. Seven residences have been destroyed.

Nearly 2,000 firefighters have been assigned to the blaze, which is 5 percent contained and has burned nearly 70,000 acres. The cause is under investigation.

"The fire continues to burn aggressively when in alignment with wind, fuel and topography," officials said.

According to CNBC, California has already spent $115 million since the start of the July 1 fiscal year, about one-fourth of the state's emergency fund budget.

On Saturday, July 28, Gov. Jerry Brown issued a state of emergency for Lake, Mendocino and Napa counties due to the River, Ranch and Steele fires.

Also on Saturday, Brown also announced that the President Donald Trump signed a presidential emergency declaration that would allow direct federal assistance to further support the communities impacted by the Carr Fire.

The Ferguson Fire, which has consumed over 57,000 acres near Yosemite National Park, forced the closure of Yosemite Valley on Wednesday, July 25. Two firefighters have died while battling the blaze.

Poor air quality and visibility were attributed to the fire. Officials cautioned park visitors that smoke could be heavy at times.

The area is set to reopen on Friday afternoon, Aug. 3, according to the National Park Service.

The Cranston Fire, burning in the San Jacinto Mountains east of Los Angeles, is 57 percent contained and has burned over 13,000 acres.

The cause of the blaze has been attributed to arson. Cal Fire officials arrested Brandon N. McGlover, 32, of Temecula for allegedly setting multiple fires in southwestern Riverside County on July 25, 2018.
