Windblown ash particles may be too large to be detected by air quality instrumentation and not reflected in the Air Quality Index (AQI) map. However, they are typically visible to the naked eye either in the air or on outdoor surfaces. Although the AQI may show green, hazardous ash may be present in the air. If you smell smoke or see ash, please take precautions. See https://www.aqmd.gov/smokesafety for details.
