Cal Fire released updated fire hazard maps for dozens of cities and towns in inland Northern California. All but one saw an increase in the number of acres in zones with heightened fire safety regulations.

With streaks of yellow, orange and red, Cal Fire’s new fire risk maps make plain the extent of fire danger in the Bay Area. The origin of the maps date back to one of the first major wildfires to burn into neighborhoods in the state: the 1980 Panorama Fire in San Bernardino County.
