More than 3.5 million additional acres across Southern California, including Los Angeles County, have been designated as fire hazard zones under updated maps released on Monday by the California Department of Forestry and Fire Protection (Cal Fire).

All told, the size of orange and red patches on the new maps is 3,626 square miles — an area nearly twice the size of Delaware.
