The California Department of Forestry and Fire Protection has updated its classification of areas that are more at risk of being affected by wildfires. The new fire hazard severity zone map shows which California neighborhoods are considered “very high” zones while others can be classified as “high” or “moderate.

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.

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