AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Local activity and stagnation early morning at the Durango monitor pushed PM-10 into the Moderates yesterday. Although these concentrations were fairly high around 7am, the increased mixing from daytime heating cleared out airborne PM levels by 10am, resulting in excellent air quality for the rest of the day. Looking ahead, the weather pattern has not changed much since yesterday. We’re still on track to be under the influence of an upper-level trough through Thursday. Surface winds are expected to be light. However, upper-level winds will still be breezy, generating sufficient mixing and ventilation. Ozone will continue to increase slightly and remain in the low-Moderates. Those breezy upper-level winds will help keep this pollutant relatively low. Once the trough exits by Thursday, calm weather will be over Arizona, allowing ozone to increase once again. As for PM-10, concentrations should be low with the exception of morning and evening hours. Stagnation during these hours can be enough to allow for elevated levels near the surface as a result of local activity. Therefore, expect the Moderate trend to remain. –P.
