SAN FRANCISCO, Sept. 28. Wildfires in California have burned more than 3.75 million acres (15,175 square km) of land this year with 26 fatalities as of Monday, according to California Department of Forestry and Fire Protection (Cal Fire).

More than 66,000 people were under evacuation orders from several fast-growing new wildfires by Monday afternoon, about 54,000 of them due to Glass and Shady fires in Napa and Sonoma counties, according to California Governor’s Office of Emergency Services.

The Glass Fire, the largest currently burning in the Bay Area, swelled to 36,236 acres (147 square km) with zero containment by Monday evening, according to updates by the Cal Fire.

The Zogg Fire, starting on Sunday in Shasta County, exploded to 31,237 acres (126 square km) Monday and remained uncontained with three fatalities and 146 structures destroyed, according to Cal Fire unit’s tweet.

The state-largest-ever fire, August Complex, has expanded to 902,463 acres (3,652 square km) with 45 percent contained as of Monday afternoon. The 306,135-acre (1,239 square km) North Complex was 78 percent contained.

A red flag warning was in effect on Monday for much of northern California as hot and dry conditions continued through the day, the Cal Fire said.

Due to the ongoing evacuations and threatening wildfires, Santa Rosa City Schools said that it would cancel all online classes Tuesday and Wednesday. (Xinhua)
