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 will keep the fair and warm weather coming through Thursday. Coastal clouds nights and mornings will increase Friday and Saturday. A low pressure trough will dive down the west coast this weekend, bringing much cooler weather, gusty winds and showers to the region, especially Sunday and Monday. The trough will slowly move out Tuesday and Wednesday.
High pressure building 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. Fortunately, these anomalously warm temperatures don`t look to last long as models are in excellent agreement that an approaching Pacific trough will follow by Saturday. While still well offshore, cooler air will begin advecting into our area pushing high temperatures down into the mid 90s. With this transition to a cooler airmass, windy conditions are expected across our CWA possibly pushing many locations into wind advisory criteria on Saturday. Look for the possible combination of air quality/long-range visibility issues from lofted dust/sand as well as more localized areas of blowing dust causing surface visibility reductions.
