The Mosquito fire in Northern California burned 64,159 acres (about 100 square miles) and was 20 percent contained on Thursday, September 15, according to Cal Fire.
The Placer County Sheriff’s Office reported that 70 structures had been destroyed and around 9,236 homes were threatened by the fire burning in parts of Placer County and El Dorado County, California.
According to Cal Fire, favorable weather conditions on September 15 would push out the smoke inversion and allow clear air to settle over the fire.
