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: Yesterday, PM-10 (dust) remained in the Good Air Quality Index (AQI) category around the Valley, thanks to rain earlier this week. However, as anticipated, PM-2.5 (smoke, soot) rose back into the Moderate AQI category at most PM-2.5 monitors in Phoenix. So far this morning, PM-10 levels have been running low around most of the Valley. Areas south and west of the Phoenix metro area are seeing the highest levels, which is typical. PM-2.5 levels, on the other hand, are elevated throughout parts of the Valley; they have been elevated since late last night. Looking ahead, warm and sunny weather is expected each day through this forecast period; high temperatures will hover around the mid-70s. And, outside of breezy, easterly winds tomorrow afternoon, winds are expected to be generally light. No rain is forecast in the near future. Air quality-wise, PM-10 will continue to be forecast in the Good AQI category. PM-10 should remain relatively low in most areas around the Valley. The main uncertainty, though, is the amount of local activity in areas south and west of the Phoenix metro area. These areas are expected to see the highest PM-10 levels, which could approach the Moderate AQI category. PM-2.5 will continue to be forecast in the Moderate AQI category, due to overnight and morning stagnant conditions generally expected each day. The main exception to this will be Saturday, during which winds will help to limit overall PM-2.5 levels. The longer the winds last into the evening, the greater the chance they will have at reducing PM-2.5. PM-2.5 levels should be lowest on Saturday, increasing afterwards. Check back tomorrow for the next Phoenix air quality forecast. Until then, have a good day! –M.
