Forecasted Air Quality Impacts

Blowing dust may result in Air Quality Index (AQI) levels that are Unhealthy for Sensitive Groups or worse in most of Los Angeles, Orange, and Riverside Counties in the South Coast Air Basin and the Coachella Valley.
High PM10 levels in the region are a result of gusty Santa Ana winds, which can lift dust and soil into the air
Winds from the north to northeast might reach 30 to 40 mph with gusts up to 70 mph
High winds may also disperse ash from the Palisades, Eaton, Hurst, Kenneth, Line, Airport, and Bridge fire burn scars
Windblown ash from burned structures may contain higher air toxic levels. If you see windblown ash, take precautions to reduce exposure
Wind speeds and PM10 levels are expected to decrease throughout the region starting Wednesday 10 PM
Air quality can vary by hour and location depending on wind conditions
