On Friday, the South Coast Air Quality Management District issued a smoke advisory for the fourth consecutive day, largely due to the elevated levels of unhealthy pollution billowing from the Eaton Fire in Altadena.

Here's advice from SCAQMD: Avoid using indoor or outdoor wood-burning appliances, including fireplaces. Avoid vigorous physical activity. Keep windows and doors closed. Avoid using a swamp cooler or other fan that brings in outside air.
