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 continue hot weather inland through Wednesday...followed by slow cooling into next weekend as high pressure aloft weakens and a weak low pressure trough develops along the coast. A disturbance, in addition to moisture aloft and weak instability, will continue to produce a slight chance for showers and thunderstorms over the mountains, high deserts, and Coachella valley through early evening. Residual moisture will produce a slight chance of afternoon and early evening mountain thunderstorms Wednesday. Main threats from thunderstorms are dry lightning and gusty winds. The marine layer and onshore flow will keep coastal high temperatures cooler with areas of night and morning low clouds and fog.

High pressure will move somewhat north and east of Arizona this week allowing warm temperatures to prevail, but also bring a couple of weather disturbances through the state. An increase in monsoon moisture will accompany these weather systems providing a threat of afternoon and evening showers and thunderstorms the remainder of week
