The highest AQ index in California (as of 7:00 PDT) is currently the Colfax area. Particle Pollution (PM2.5) is measuring at 55 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Ozone (OZONE) will be in the Brawley area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Today and tomorrow, as an upper-level low pressure system gradually passes north of the Imperial Valley, vertical mixing will be enhanced. However, sunny skies and temperatures in the mid-80s will be sufficient for ozone formation, yielding low-Moderate AQI levels on both days.
