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.

As thousands of acres burn across Southern California, wildfire smoke is causing poor air quality in the region and beyond.

How bad is the air? The South Coast Air Quality Management District monitors particulates in our region. SCAQMD says much of the Los Angeles basin’s air is unhealthy for sensitive people. And the closer you get to the fires, the worse it gets.
