Wildfires have consumed over 4 million acres in California this year, more than doubling the previous record set during the 2018 season.

As of Oct. 7, 16,500 firefighters in the Golden State are battling 22 major wildfires, which have led to at least 31 fatalities and the destruction of close to 9,000 structures, Capital Public Radio reports. The August Complex – now the largest fire in California history – has grown to reach 1.01 million acres and has claimed the life of one firefighter and injured another. It is at 60% containment.

The Glass Fire, burning for just under two weeks in Napa and Sonoma Counties, has expanded to 67,420 acres, destroying 1,517 structures, 636 of which were homes. It is at 62% containment.

The blaze, which is 170,996 acres and just 14% contained as of Oct. 8, has crossed the border into Colorado, prompting mandatory evacuation notices for parts of Jackson and Larimer Counties.

To date, the Mullen Fire has destroyed 29 homes, 31 outbuildings, and one firefighter has been injured. Officials predict strong winds and warm temperatures heading into the weekend; however, a cold front is forecast for Saturday evening, bringing with it moisture and even snow at higher elevations.

Elsewhere in Colorado, the Cameron Peak Fire that began in mid-August, and is now the third largest in state history, reached 128,149 acres as of Oct. 6, Fox 21 News reports. More than 1,000 firefighters are working on the blaze, now at 42% containment.

In response to continued fire activity, Gov. Jared Polis on Wednesday (Oct. 7) extended his statewide fire ban on campfires and other open burning for another 30 days, according to The Durango Herald.

In Oregon, nearly every active incident has reached at least 50% containment, The Oregonian reports, with the exception of the 204,435-acre, 46%-contained Lionshead Fire. Additionally, as of Oct. 7, three fires have been at least 90% contained, and only three others experienced growth overnight.
