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 Friday, August 16, 2019 Not much change in the day to day weather as the Monsoon (or as some have referred to it this year, ‘Non-soon’) takes a break over the next several days. A weak trough will pass by well to our north this weekend and help knock down the afternoon temperatures a few degrees, though it will still be hot! Diurnal winds (light early morning easterly winds that becoming westerly in the afternoon) and abundant sunshine will be the norm over the next several days. The forecasted ozone levels are in the upper good to mid-moderate range (northern portions of the County) as afternoon winds should be breezy enough to keep the ozone levels at bay this weekend and early next week. Not to mention the sun angle and amount of daily sunlight are on their slow downward trend. The particulates are forecast to be in the good to low moderate, excluding Hidden Valley which has forecasted particulates in the mid-moderate range, mainly due to the expected early morning PM10 and PM2.5 spikes. Check back on Monday for an updated air quality forecast.
