The fire agency said in late afternoon on social media that the forward progress of the second blaze, the Hawick fire, had been stopped.

A brush fire in the Lakeside area grew to more than 850 acres Wednesday, which kept Cal Fire firefighters on the scene and evacuees from accessing their property for a second day.

Face masks, such as N-95s and KN-95s, as well as indoor air filtration will help with the smoke and particulate matter, experts said.
