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)

Forecast Discussion: Updated Friday, July 19, 2019 The Monsoon high will reestablish itself over the Four-Corners area late Sunday and early next week. This will mean more favorable conditions for storm development over the mountains to our east and also for areas in southern Arizona. Strong outflow winds are forecast to make their way into the desert locations and bring blowing dust and elevated particulates. Therefore a PM10 High Pollution Advisory (HPA) may be issued for Monday as a precaution, check back on Sunday for an updated air quality forecast. The forecasted outflows are for late afternoon and evening hours and so that’s when the highest levels are particulates are expected. Anyone with respiratory and or heart ailments should limit outdoor activities during those times on Monday. Unfortunately at this point in time it doesn’t look like Monday will be a widespread rain event so not all areas will get precipitation which doesn’t bode well for Tuesday which may be another active day storm wise, stay tuned. The ozone levels are forecast to be in the good to upper moderate (northern areas) range on the AQI scale the next several days. At this point have the Apache Junction forecasted ozone levels below the health watch criteria (90-100 on the AQI scale). As the Monsoon activities kick off the ozone levels should drop accordingly due to cloud cover and strong winds. Stay up to date with current air pollution levels by checking the near real-time PM10, PM2.5 and ozone levels online at http://www.pinalcountyaz.gov/AirQuality/Pages/AirQualityReport.aspx.
