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 Friday, February 14, 2020 What can be said? Sounds like a broken record, this holiday weekend will be another wonderful weather weekend with dry conditions and comfortable temperatures. No significant weather changes are expected through early next week. Early morning temperatures inversions will help trap particulates close to the ground and elevate them a bit, especially in/around Hidden Valley which is forecast to reach the moderate AQI category Sunday through Tuesday. The rest of the PM10 monitoring locations are forecast to remain in the good AQI category through the weekend and early next week mainly because the ground surfaces are still relatively saturated and will take some time (week or two) to dry out enough to where it will affect the overall daily PM10 averages. The ozone levels are forecast to remain in the good AQI category since it’s still too early in the year to where the sun angle is relatively low in the sky and the temperatures aren’t warm enough to cause a significant bump in the ozone levels. Looking at the longer range forecast (middle to end of next week), a weak upper level low pressure system may develop to our north and west. At this point, the area of its development and the projected patch into/through our area make it most likely a dry system. Stay tuned and check back on Tuesday for an updated air quality forecast.
