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
A weak low pressure system near the California coast will maintain mostly dry southwest flow aloft…but with some afternoon clouds near the mountains at times. High temperatures will fluctuate within a few degrees of average. The marine layer and weak onshore flow will continue areas of night and morning low clouds and patchy fog extending into the western alleys…with gusty southwest to west winds in the mountains during the late afternoon through late evening each day.
Dry conditions continue region wide today. Monsoon moisture returns to southeast Arizona beginning Wednesday. Meanwhile, temperatures climb above normal today and Wednesday. Moisture overspreads the rest of Arizona and far southeast California by Friday. Storm chances will follow this same trend and continue into early next week. As is typical, the best chances for showers and thunderstorms will be over the higher terrain of Arizona. With higher humidity and more cloud cover, max temperatures trend downward late this week and over the weekend.
