The highest AQ index in California (as of 12:00 PDT) is currently the Coachella Vly area. Ozone (OZONE) is measuring at 80 (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 E San Bernardino area. It is forecasted to be Unhealthy, meaning some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.
