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
Weak troughing over the west will bring quiet weather through the weekend. Temperatures will be slightly cooler than average, and the marine layer will become a little deeper. Early next week an upper ridge builds over the Southwest for hotter weather and a shallower marine layer

A drier and more stable airmass will slowly move into the region through Thursday. However a slight chance of afternoon and evening thunderstorms will remain over the mountains north through east of Phoenix. On Friday, a surge of monsoon moisture will return to southern Arizona resulting in a threat of afternoon and evening thunderstorms over portions of south central Arizona, while southwest Arizona and southeast California remain dry and stable. A strong high pressure system will subsequently build into the region Sunday through the middle of next week for dry weather and much warmer afternoon temperatures
