Forecast Discussion: Today, an upper-level ridge of high pressure will limit atmospheric mixing, trapping pollutants near the ground. Furthermore, moderate west-southwesterly winds will transport regional pollutants into the Imperial Valley, and hot, sunny conditions will enhance ozone formation. As a result, ozone levels will be Unhealthy for Sensitive Groups. Tomorrow, moderate to strong westerly winds will help to disperse pollutants throughout the day. However, sunny skies and warm temperatures will continue to aid ozone production in the Imperial Valley. As a result, ozone levels will be Moderate.
