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, October 19, 2018 An upper level low pressure system off the southern California coast this weekend will help usher in atmospheric moisture and bring chances for showers and perhaps a thunderstorm or two. Have increased Saturday’s and Sunday’s PM10 forecasted values a bit and added a mention of blowing dust as there is a slight chance for some pop-up thunderstorms and associated localized outflows. Even though the forecasted PM10 levels are elevated a bit over the weekend, they are still in the good AQI category. Ozone will continue to be the highest pollutant and will be in the middle of the good AQI category. The chances for showers remain for Monday, though in areas to the south and east. The longer range forecast has high pressure building into the area for the second half of next week. Enjoy the good air quality and warm temperatures the next few days. Check back on Monday for an updated air quality forecast.
