The highest AQ index in California (as of 22:00 PST) is currently the Bishop area. Particle Pollution (PM2.5) is measuring at 129 (Unhealthy for Sensitive Groups). This means members of sensitive groups may experience health effects. The general public is less likely to be affected.
Over the next few days, the highest Particle Pollution (PM2.5) 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, light northwesterly to northerly winds will aid dispersion and transport cleaner air into the Imperial Valley as a surface ridge of high pressure lingers to the north. However, morning and evening temperature inversions and periods of calm winds will allow pollutants to accumulate, leading to low-Moderate AQI levels on both days.
