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, April 23, 2018 ** OZONE HEALTH WATCH MONDAY & TUESDAY, APRIL 23-24, 2018 ** Hidden Valley PM10 levels are off to a fast start this workweek as hourly average levels have surpassed 1,000 ug/m3 for a couple of hours early this morning. Therefore today’s PM10 forecast has been increased into the Unhealthy for Sensitive Groups (USG) AQI category since the 24-hour average PM10 is expected to exceed the health standard. Unfortunately not much is expected to change this week as high pressure controls the area. Morning temperature inversions will help trap particulates close to the ground and local dust causing activities will play a large role in overall PM10 concentrations. Hidden Valley will be the area of concern this week as the forecasted PM10 levels over the next several days are over the health standard. Ozone is another pollutant of concern this week as afternoon high temperature reach the middle to upper range of the 90s under mostly sunny skies. The forecasted ozone levels are in the upper range of the moderate category today through Wednesday. Therefore an ozone health watch remains in effect today and has been extended into Tuesday. Anyone with respiratory and/or heart ailments should limit outdoor activities during the afternoon and early evening hours when the ozone levels are typically at their highest. The PM2.5 levels will be elevated at Hidden Valley and are forecasted to be in the upper range of the moderate AQI category, though just below the health watch criteria.
