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 Thursday, April 26, 2018 ** OZONE HIGH POLLUTION ADVISORY (HPA) THURSDAY, APRIL 26, 2018 ** One more day of elevated ozone levels as the levels approach and perhaps exceed the health standard this afternoon. Therefore today’s ozone High Pollution Advisory (HPA) remains in effect as a precaution to those with respiratory and/or heart ailments. A break in the ozone levels as the work week comes to an end Friday. The ozone levels will drop back into the middle and upper range of the moderate AQI category Friday due to lower emissions and less favorable winds. Morning temperature inversions and light winds along with local dust activities in/around Hidden Valley bring continued daily chances for PM10 exceedances today and again on Friday. Local dust controls will go a long way towards limiting PM10 exceedances at Hidden Valley. The PM2.5 levels will remain elevated at Hidden Valley and are forecasted to be in the middle of the moderate AQI category. Less favorable winds (for elevated PM10) over the weekend should help limit the daily average PM10 at Hidden Valley (mid-upper moderates). A large upper level low pressure system currently several hundred miles off of the coast of northern California will eventually move eastward and onshore this weekend/early next week. This system will move well to our north and bring locally breezy conditions over the second half of the weekend/early next week. Some localized blowing dust is expected during this period of time, however the overall forecasted PM10 levels are in the middle of the moderate AQI category. Another low pressure system next week is projected to move over the area and bring stronger winds and even the chance for some much needed precipitation. Stay tuned.
