SAN FRANCISCO (CBS SF) — A layer of unhealthy, smoky air from the CZU Lightning Complex wildfire stalled over the San Francisco Bay Area Friday, triggering an air quality warning and forcing local residents to remain indoors with their windows closed.Alameda County Omicron Variant Outbreak Victims Attended Wisconsin Wedding Last Weekend
The offshore winds that had helped clear out the Bay Area skies on Thursday had all but disappeared. Combined with a marine layer of low fog, the overcast skies turned cloud-covered and gray.

“The stable air mass may also play a role in decreased air quality over places like the SF Peninsula as smoke becomes trapped within the boundary layer,” the National Weather Service warned.
