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 Tuesday, May 26, 2020 ** OZONE HEALTH WATCH IN EFFECT TUESDAY, MAY 26, 2020 ** The second heat wave of 2020 is on its way this week as high pressure builds into the area. The afternoon highs will reach triple digits and strive to reach 110 degrees later in the week and this upcoming weekend. The ozone levels are going to approach the health standard today in northern areas and some afternoon breeziness on Wednesday and Thursday are expected to limit ozone formation and transport and so have slightly lower forecasted ozone levels. However late in the work week (Friday) lighter winds and much warmer temperatures are expected to result in ozone exceedances. So an ozone High Pollution Advisory (HPA) may need to be issued. Stay tuned. The PM10 levels everywhere except for Hidden Valley are forecast to be in the good to low moderate range this week. Hidden Valley’s early morning wind conditions coupled with locally generated dust will play a large part in the daily PM10 levels this week. For example, this morning’s winds around Hidden Valley have been light and variable with brief periods of easterly winds which have brought the locally generated dust to the monitor and hourly PM10 averages have ranged from 308 ug/m3 all the way up to 1,102 ug/m3 and so today will be the second PM10 exceedance day at Hidden Valley of 2020. The next couple of morning’s the early morning wind conditions are forecast to have more westerly to northerly components as the high pressure builds into the area from the west and so the daily PM10 concentrations at Hidden Valley are forecast to be below the health standard. However later in the week, lighter winds from an easterly direction are expected and so PM10 levels are forecast to approach and perhaps exceed the health standard. Check back tomorrow for an updated air quality forecast. Forecaster: S. DiBiase
