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 Thursday, September 21, 2017 ** PM10 HIGH POLLUTION ADVISORY IN EFFECT THURSDAY, SEPTEMBER 21, 2017 ** Gusty winds this afternoon associated with an approaching upper level low pressure system and dry cold front will cause widespread blowing dust and elevated PM10 levels. PM10 exceedances of the health standard are now expected and so the PM10 Health Watch originally issued for today has been upgraded to a PM10 High Pollution Advisory (HPA). Anyone with respiratory and/or heart ailments should remain indoors during periods of blowing dust. The breezy conditions will continue into Friday, however the winds aren’t expected to be quite as strong as today, therefore the highest forecasted PM10 levels will be in the mid/upper range of the moderate AQI category. Less winds and much nicer weather over the weekend with afternoon highs only in the 80s. The PM10 levels will mainly be in the good AQI category with only the usually elevated PM10 locations (i.e. Hidden Valley, Stanfield) in the low/mid moderates. The ozone levels will be in the upper good AQI category for the foreseeable future as cooler temperatures keep ozone levels in check. PM2.5 levels will follow behind PM10 and be in the good to moderate range of the AQI scale. Forecaster: S. DiBiase
