On August 19, local time, a fire in the mountainous area at the junction of San Mateo County and Santa Cruz County, California, was spreading rapidly. The fire consisting of 22 fires burned at least 4,000 hectares of land and forced the evacuation of more than 22,000 people. On that day, many wildfires burned over 250,000 acres of land in the San Francisco Bay Area, and tens of thousands of people were evacuated.

  Due to strong winds and high temperatures, many wildfires have spread rapidly in Northern California recently. Except for San Francisco County, all counties in the Bay Area have been affected. The California Department of Forestry and Fire Protection said the fire has burned more than 100 buildings in the area. The dense fires caused smoke to drift in all directions, and the San Francisco Bay Area and parts of central California became the regions with the worst air quality in the world that day.
