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.

Forecast Discussion: Updated Friday, October 20, 2017 Yesterday morning’s easterly to northeasterly winds at Hidden Valley helped transport local emissions over to the monitor. As a result the PM10 health standard was exceeded at Hidden Valley, the 28th PM10 exceedance day of 2017. A trough will move by to our north today and bring breezy conditions. Some blowing dust is expected and a slight bump up in PM10 levels in most places (Excluding Hidden Valley). Overall the PM10 levels are going to be in the upper good to mid-moderate range on the AQI scale. Hidden Valley is forecasted to be in the mid to upper range of the moderate AQI category today and Saturday. High pressure will build into the western United States this weekend and early next week. A rise in temperatures will take place as the ridge of high pressure builds and a pressure surface gradient will create easterly to northeasterly winds, breezy at times. The PM10 levels at Hidden Valley are once again expected to rise on Sunday and early next week. Have forecasted PM10 levels at Hidden Valley in the upper range of the moderate AQI category for Sunday and Monday and slightly higher (unhealthy for sensitive groups) on Tuesday. Stay up to date with current air pollution levels by checking out the near real-time PM10, PM2.5 and ozone levels online at http://www.pinalcountyaz.gov/AirQuality/Pages/AirQualityReport.aspx. The PM2.5 levels will follow behind the PM10 levels and be in the range of upper good to upper moderate on the AQI scale. The ozone levels are expected to be in the upper good range on the AQI scale: Forecaster: S. DiBiase
