Several parts of southern California are currently under windblown dust and ash advisories as deadly wildfires continue to burn. Here's how to protect yourself.

Ash from the recent LA County fires and burn scars formed by other wildfires in the fall can be dispersed by strong winds. See an air quality map.

Wildfire smoke causes particularly dangerous air quality, especially for sensitive groups including children and pregnant people.

A dust and ash advisory has been issued for L.A. County until 7 p.m. Wednesday "due to harmful particle pollution levels from windblown dust and ash."

With another surge of fierce Santa Ana winds, residents were asked to remain vigilant. An Air Quality Alert has been extended for many portions of LA County through Wednesday evening.
