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 high pressure aloft will move across Southern California today with a weak upper level low-pressure system moving into California on Wednesday. High temperatures near to slightly above average today and Wednesday. Following will be a weak high pressure aloft with 5 to 10 degrees above average for Thursday and Friday. Lowest temperatures early this morning in the upper deserts will fall into the upper 20s to mid 30s with areas of frost.

For late in the weekend into early next week a trough of low-pressure will move inland along the West Coast. This will bring slow cooling on Saturday with greater cooling for Sunday and Monday.

Overall, mostly weak offshore low-level flow will persist into Friday with locally gusty northeast winds near the coastal foothills and below passes and canyons accompanied by a slow warming trend taking inland high temperature 5 to 10 degrees above average for Thursday and Friday.

A low-pressure system will leave behind much cooler temperatures for Tuesday with highs in the 70s on the low deserts. Temperatures will warm slightly on Wednesday with little change the rest of the workweek. A stronger low-pressure system will result in increasing cloudiness and precipitation chances across the region during the weekend and into early next week.
