  • A Smog Advisory is related to the Air Quality Index (AQI), which rates how clean the air is.
    • The AQI scale ranges from 0 to 100+.
    • Higher numbers mean higher health risks.
    • 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.
  • Smog is harmful to the lungs and heart.
    • Even in healthy people, smog can reduce lung function.

Winds have shifted to a southerly direction resulting in cleaner air in the forecast regions listed above.
