  • A Smog Advisory is issued in your region when the AQI is expected to reach 50 in the next 24 hours.
  • It can be lifted once the AQI is expected to reach or drops below 50.

Increasing wind speeds are allowing for good mixing and dispersion of pollutants, resulting in cleaner air in the air quality forecast regions listed above.
