"As of 0700 EST [Eastern Standard Time] on November 10, 2018, CAL FIRE reported wildfires in Butte County, CA had burned more than 100,000 acres and was 20 percent contained as seen in Figure 1. The cause of the fires is currently unknown. The wildfires are expected to be fully contained by November 30th. Northeast winds are expected to decrease in strength into the afternoon. The fires will continue to burn in drainages to the north and northeast. The fire continues to burn to the northwest into Magalia and toward Stirling City. Extremely dry fuels and heavy fuel loads in combination with low relative humidity are contributing factors which will aid in fire intensity and size, potentially impeding control efforts. The fire burned through Paradise and Concow Thursday; these areas will likely continue to experience active burning throughout Saturday. Friday night, the fire burned to the southwest toward Chico and Butte Creek Canyon and South. The fire crossed Highway 70 near Pulga and is expected to continue to burn east, southeast toward Yankee Hill. More than 2300 personnel, 300 fire engines, 20 dozers and nearly 20 helicopters are currently involved in fire-fighting efforts. Numerous air tankers from throughout the State are flying fire suppression missions as conditions allow."
