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 Thursday, March 30, 2017 An upper level low pressure system will move into the area today and slow down and meander around for a day or so. Unfortunately no precipitation is expected with this system. Today is featuring interesting conditions from a PM10 perspective. Light winds and a temperature inversion this morning have helped elevate PM10 concentrations in the Hidden Valley area. Additionally, the winds will pick up in intensity this afternoon and reach gusts near 30 mph! Therefore blowing dust is likely as well. Breeziness will continue on Friday as the system continues to impact the area. However the winds aren’t expected to be quite as strong as today and so decent ventilation should help lower the PM10 concentrations a bit. The upper level low pressure system will slowly progress eastward on Saturday and eventually exit the area. Not much expected weather-wise on Saturday and the same can be said about dust causing activities, therefore have good AQI forecast for PM10 and PM2.5. A weak ridge of high pressure on Sunday will result in a nice day, light winds and pleasant temperatures. A morning temperature inversion may help trap particulates briefly on Sunday and result in slightly elevated PM10 levels, however the forecast range is good to low/mid moderate on the AQI scale. The ridge will be short lived as a trough moves in early next week and increases the winds yet again. Stay tuned. The ozone levels over the next several days are expected to be in the good to low moderate range. Forecaster: S. DiBiase
