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: Updated Tuesday, July 11, 2017 Late evening and overnight storm activity brought some much needed rain to portions of the county. Apache Junction/Queen Valley, San Tan Valley, Florence, Eleven Mile Corner and Arizona City all received measureable precipitation. The PM10 levels are significantly lower than they have been with only Hidden Valley and Maricopa slightly elevated. The next several days will feature favorable conditions for the Monsoon fueled storm activity. The daily question will be whether the storms that develop over the mountains are able to make their way down into the deserts. The PM10 forecasts are mostly in the good AQI category due to the aforementioned rain in addition to the likelihood that more widespread rain will be taking place this week. The PM2.5 levels will be in the good AQI category as well. The wildcard pollutant this week will be ozone as Apache Junction yesterday exceeded the health standard for the 13th time in 2017. Usually the ozone levels drop at the onset of the Monsoon, not so in 2017. Therefore we’ll have to keep tabs on the daily ozone levels in northern Pinal County this week. If the Monsoon storms either don’t materialize or else start late in the day and there is plenty of sunshine prior to the storm activity along with favorable transport winds from the Phoenix metro then the ozone levels can and probably will approach and exceed the health standard. Those are a lot of ‘ifs’ and as such, have ozone forecasts that are in the middle of the moderate AQI category for northern portions of the County with good levels elsewhere. Check back tomorrow for an updated air quality forecast. Forecaster: S. DiBiase
