Data from Cal Fire shows that the Mosquito Fire, which is located in Placer County, had grown to 64,159 acres as of Thursday morning and is currently 20 percent contained. On Monday morning, the fire had burnt 46,587 acres and by Monday night, Cal Fire officials said the fire had grown to 48,700 acres.

While the Mosquito Fire is currently burning in the Northern part of California, the southern part of the state recently saw a wave of extreme weather incidents over the past week.

Parts of Los Angeles experienced mudslides over the past weekend due to heavy rainfall brought by remnants of Hurricane Kay. California’s Canoga Park experienced a 2.6 magnitude earthquake on Monday and several other wildfires are actively burning across the state.

“Firefighters continue to hold the Mosquito Fire inside established control lines with the help of cooler temperatures and higher humidity. Throughout the day, crews continued to patrol, mop up and secure control lines along the Foresthill Road corridor, with a heavy focus on the area where yesterday’s spot fire made an aggressive run towards the community,” Cal Fire officials said in a status update on Wednesday night. “The Mosquito Fire’s eastern front continues to steadily grow with active fire behavior into densely forested areas with critically dry fuels and little fire history.”

In addition to using helicopters to help assist firefighters to extinguish the fire, Cal Fire said that they are also utilizing “mobile retardant bases,” and “Unmanned Aerial Systems.”

According to Cal Fire, the Mosquito Fire has damaged at least 10 residential and commercial structures, while 64 structures have been destroyed.

In a video posted to Facebook on Wednesday, Placer County Sheriff Lieutenant Josh Barnhart said, “I’m happy to report that as of yesterday afternoon, we have not added any more evacuation zones…if we do by chance have to issue orders in those warning zones, just be ready to go.”

“Approximately 6,000 homes collectively remained threatened at this time,” Barnhart added.

After the Mosquito Fire surpassed the 63,000-acre mark, it became the largest active wildfire of the year for California, surpassing the McKinney Fire.

According to the Los Angeles Times, Jonathan Pangburn, a fire behavior analyst with Cal Fire said on Wednesday that firefighters battling the Mosquito Fire are currently facing dry fuel conditions and predicted “an absolute blowup out here,” for the fire’s Eastern region.

California is also actively battling other fires, including the Mountain Fire which has burned over 13,000 acres and is 75 percent contained, and the Fairview Fire, which has burned over 28,000 acres and is also 75 percent contained.
