Schools and universities canceled classes because of the unhealthy air quality billowing over the Bay Area from the Camp Fire in Butte County.

The West Contra Costa Unified School District sent out a notice saying that schools will be closed on Friday.

"Students and teachers will get an early start to the Thanksgiving holiday break and I hope the extra time will allow you to recover from the difficult week we have experienced," Supt. Matthew Duffy wrote. "Making the decision to close schools is never easy. During last year’s North Bay fires, the air quality was significantly worse throughout much of the Bay Area, but impacted fewer days. The smoke from the Camp Fire has not reached last year’s levels, but has lasted a longer period of time."

Oakland Unified School District, all public schools within Alameda County, and Mt. Diablo Unified School District also announced that classes will be canceled on Friday. Additionally, AC Transit announced a one-day cancellation of service to schools in Alameda and Contra Costa counties in response to the school closures.

The air quality was even worse on Thursday than it has been the previous week, when the wildfire broke out nearly two hours from the Bay Area.
