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.

Millions woke up to hazy skies and poor air quality Wednesday morning as crews continued to fight the Palisades Fire in western Los Angeles, the Eaton Fire near Altadena and the Hurst/Sylmar Fire near Santa Clarita.
