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 Monday, June 24, 2019 ** OZONE HEALTH WATCH MONDAY JUNE 24, 2019 ** The Woodbury fire (https://inciweb.nwcg.gov/incident/6382/) in the Tonto National Forest (http://www.facebook.com/TontoNationalForest/) grew to over 96,000 acres over the weekend and is 25% contained. According to the United States Forest Service Wildland Fire Air Quality Response Program, the concern for the local area at this point is for smoke impacts. The Arizona Department of Environmental Quality (ADEQ) has set up a temporary PM2.5 monitor in Blue Point and Queen Valley (https://www.phoenixvis.net/PPMmain.aspx). Keep track of fire with the links above (InciWeb, Tonto National Forest Facebook page, ADEQ Queen Valley PM2.5 monitor) and on Twitter (https://twitter.com/TontoForest). The best chances for smoke impacts for the populated areas will be during the overnight and early morning hours when winds will be at their lightest and from an easterly wind direction. The good news is typically during the overnight periods the fire activity is reduced due to the cooler temperatures and the increase in relative humidity. Additionally the winds switch to southwesterly to westerly directions during the midday and afternoon hours and blow the smoke away from the more densely populated areas. Weak high pressure today will help elevate the ozone levels in northern portions of the County today into the upper range of the moderate AQI category in northern portions of the County. An ozone health remains in effect today as the ozone levels may approach and perhaps exceed the health standard. The combination of potential smoke impacts from the Woodbury fire and elevated ozone levels pose a health risk. Anyone with respiratory and/or heart ailments should limit outdoor activities when smoke is present and also during the afternoon and early evening hours when ozone levels are at their highest. Less favorable afternoon conditions (i.e. winds from a southwesterly direction) on Tuesday mean slightly lower ozone levels are forecast. An upper level low pressure system over the Pacific will arrive into the Pacific Northwest during the second half of the workweek and slowly migrate eastward. For the most part that system will not directly impact the area with any weather to speak of, about the only impact for the local area will be afternoon breeziness. The afternoon high temperatures will rise a bit each day and reach the 103-108 degree range by Thursday/Friday. The particulates will be mainly in the good AQI category, excluding Stanfield and occasionally San Tan Valley which are forecast to reach low moderate. Hidden Valley PM10 level are forecast to reach the middle and upper range of the moderate AQI category this week due to favorable early morning conditions (stagnant) and the usual weekday uptick in local dust generating activities.
