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 off the Southern California coast will bring slight cooling through early next week. Residual mid level monsoonal moisture will maintain a slight chance of afternoon and early evening thunderstorms...mainly near the mountains...for the next few days. Drier southwest flow aloft for next week is expected to end the thunderstorm chances. A little warmer for the middle part of next week for inland areas...then a little cooler into next weekend. The marine layer and weak onshore flow will bring areas of night and morning low clouds and patchy fog to coastal areas.

The weak upper level low pressure system off the Southern California coast will move slowly inland early next week...followed by high pressure aloft to the southwest. This will bring slight cooling early next week...followed by slow inland warming for the middle part of next week. That low pressure system moving inland will bring drier southwest flow aloft...mostly ending the thunderstorms chances

Temperatures will remain near to slightly above the seasonal average through early next week. Modest moisture levels will persist through the weekend with occasional spotty thunderstorm chances. The primary threats from any of these storms will be gusty winds, patchy blowing dust, and very isolated heavy rainfall. The passage of a weather system during the middle of next week should allow some warming and drying across the region
