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 Wednesday, April 26, 2017, 9 a.m. Yesterday’s trough did bring breezy to gusty winds with the strongest gusts in the 30-35 mph range along with some periods of blowing dust. The good news is the overall air quality impacts weren’t quite as bad as forecast. Most areas were in the low to mid-range of the moderate AQI category. This morning is starting off as expected with hazy conditions and some elevated PM10 levels. Eventually the winds will pick up later in the morning and be a little breezy this afternoon. No significant blowing dust is expected today and the overall air quality related to the particulates will actually improve as the day progresses. Therefore have removed the PM10 Health Watch for today and reduced the forecasted levels. The ozone levels however will be the pollutant of concern as this afternoon progresses with the highest levels expected to be in the middle to upper range of the moderate category. Another trough will move into the area by late Friday and slowly move through by the second half of Saturday. More breezy to gusty winds along with some blowing dust. Since yesterday’s winds will be similar in strength to Friday/Saturday’s winds and yesterday’s particulate levels didn’t reach extremely high levels another trough will move into the area and bring more breezy to gusty winds which are anticipated to be at least as strong as today’s wind event and perhaps a little stronger. At this point have a PM10 Health Watch possible for Friday with the chance that it gets upgraded to a PM10 High Pollution Advisory (HPA). Stay tuned and check back on Wednesday. Forecaster: S. DiBiase
