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: FORECAST SUMMARY: Monday, August 20th, 2018 through Friday, August 24th, 2018 Ozone: 8-hour Ozone concentrations will be generally Good throughout the state. PM-2.5: 24-hour Fine Particulate concentrations will be generally Good to Low Moderate. FORECAST DISCUSSION An approaching low pressure system, during Monday, will provide cloudy skies and precipitation probabilities through Tuesday. With cloudy skies and rain, ozone values will stay low. However widespread smoke from the West Coast fires can still influence our fine particulate concentrations. Wednesday and Thursday should provide good clean-out days with northerly winds, moderate temperatures and low humidity. Ozone values will be low and fine particulate numbers should also be low unless influenced by the distant fires. The upcoming weekend could be worrisome as winds turn southwest. With those winds, temperature and humidity will increase along with the transport of ozone precursor pollutants. As such, the regional forecasters have agreed to another call Friday morning to discuss the probabilities for the weekend. EXTENDED FORECAST: Air Quality is expected to be generally Low Moderate going into the weekend.
