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: High pressure that helped promote light winds and elevated ozone around the Valley yesterday has shifted eastward. In its place, stronger atmospheric flow will move over the region, beginning today. It appears this stronger flow is here to stay through this whole week. As a result, each day this week is expected to have breezy afternoon winds, generally out of the west or southwest. The good news for air quality is that these winds should help to prevent ozone from significantly accumulating. Hopefully this means we will finally have a break from high pollution advisories for a while. But, we have been surprised by ozone before. For now, ozone is forecast in the Moderate AQI each day. East and northeast parts of the Valley are likely to see the highest ozone levels due to the westerly winds. Lastly, PM-10 could potentially reach the Moderate AQI range at the West 43r monitor due to local, morning activity. Check back tomorrow for more. Until then, have a good day! –M.Graves Last Update: Sunday, April 23, 2017, 9:14 AM
