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
SYNOPSIS FROM THE SAN DIEGO OFFICE
An upper-level trough along the West Coast will maintain a deep marine layer with below average highs today, and create areas of drizzle this morning. The trough will weaken Thursday through Saturday and create a shallower marine layer with highs closer to seasonal normals. Upper-level low pressure next week could continue below normal highs and a deep marine layer.
SYNOPSIS FROM THE PHOENIX OFFICE
Relatively dry conditions will persist across the Desert Southwest through Saturday. After a brief period of below normal temperatures, a warming trend will continue into the weekend. The monsoonal flow is expected to return to Arizona Sunday, bringing an increase in moisture and a threat of thunderstorms. Afternoon and evening storms will remain in the forecast through the middle of next week along with near normal temperatures.
