More than 800,000 acres of land across these SoCal counties have been classified under the highest fire hazard severity zone level.

Cal Fire's new maps for Southern California added 3.5 million acres into fire-hazard zones, increasing the acreage in the highest hazard zone by 26%.

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.
