Be Advised
High wind levels have the potential to suspend particulate matter into the air. High levels of PM10 may pose an impact to public health. It is recommended that active children and adults, and people with respiratory disease, such as asthma, limit their outdoor activities.

Potential increases in PM10 concentrations may increase to moderate or unhealthy level.

Imperial County Weather Synopsis
High pressure aloft off the California coast will continue warm and dry weather through Thursday with high temperatures around 10 degrees above average for inland areas. Towards the coast...weak onshore flow will keep high temperatures cooler with areas of night and morning coastal low clouds and locally dense fog extending inland to the mesas and far western valleys at times. For Friday through early next week...a large cold low pressure system is expected to develop somewhere in the vicinity of Southern California bringing much cooler temperatures...periods of strong gusty west winds in the mountains and deserts...and chances for showers and a slight chance of thunderstorms for late Saturday through early next week.
High pressure building strongly over the Southwest will give the lower desert elevations another run at the first triple-digit readings of 2017 this week. Dry conditions, mostly clear skies, and generally light winds will prevail for the area. A cold Pacific low pressure system will approach the region, triggering a cool down and elevated winds Saturday, and even cooler temperatures Sunday and Monday. A slight chance of showers and storms are also forecast for the late weekend and lingering possibly into early next week as low pressure is slow to exit the Southwest.
