Forecasted Air Quality Impacts

Windblown Ash

High winds may disperse ash from the Palisades and Eaton impact zones. Winds may also disperse ash from the Hurst, Kenneth, Line, Airport, and Bridge fire burn scars
Ash impacts are possible in all areas to the south and west of these burned areas
Windblown ash particles may be too large to be detected by air quality instrumentation and will not influence Air Quality Index (AQI) levels. However, ash particles are typically visible to the naked eye either in the air or on outdoor surfaces
Windblown ash from burned structures may contain higher air toxic levels. If you see windblown ash, take precautions to reduce exposure

Windblown Dust

Blowing dust may result in AQI levels that are Unhealthy for Sensitive Groups or worse in portions of Los Angeles, Orange, and Riverside Counties in the South Coast Air Basin and the Coachella Valley.
High PM10 levels in the region may result from gusty Santa Ana winds, which can lift dust and soil into the air
Wind speeds and PM10 levels are expected to decrease throughout the region starting on Wednesday
Air quality can vary by hour and location depending on wind conditions
