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 Tuesday, March 28, 2017 Westerly to northwesterly winds will help transport ozone from the Phoenix metro into the northern portions of the county and so the ozone levels are anticipated to reach low moderates. Not quite as windy on Wednesday but still favorable wind directions will keep the ozone levels elevated. Additionally the warmest temperatures of the week will be on Thursday along with lighter winds so the ozone levels in northern and central portions of the County are expected to be at their highest levels (low to mid moderate). The PM10 levels over the next several days will be in the upper good to mid moderate range on the AQI scale with some spotty blowing dust today and again on Friday as another storm system moves into the area. Unfortunately not much in the way of local rain is expected this week. Forecaster: S. DiBiase
