Ash from the recent LA County fires and burn scars formed by other wildfires in the fall can be dispersed by strong winds. See an air quality map.

The ongoing wildfires have put the Los Angeles area under an air quality alert, with the National Weather Service advising SoCal residents to remain indoors with their windows closed and wear N-95 masks if they have to go outside.

The Bay Area’s poor air quality is adding an extra twist to the San Francisco 49ers’ home opener in Santa Clara Thursday night.
