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 trough of low pressure near the West Coast will maintain slightly below average high temperatures today. Warmer with a slightly shallower marine layer for Wednesday and Thursday as high pressure to the north expands northward. Cooling to slightly below average for Friday into early next week as another trough of low pressure develops near the West Coast. Onshore flow and the marine layer will continue areas of night and morning coastal low clouds and patchy fog extending into portions of the western valleys

A warm and very dry airmass will remain in place across the Desert Southwest this entire week continuing the significant break in the monsoon. Afternoon temperatures will generally run a few degrees above normal. A return of monsoon moisture will gradually bring chances for thunderstorms, possibly as early as Sunday over high terrain areas and then the lower deserts sometime early next week
