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
High pressure aloft over the southwest states will bring well above average high temperatures through mid week...peaking Tuesday and Wednesday. A shallow marine layer and weak onshore flow will moderate the heat towards the coast with areas of night and morning low clouds and fog. High pressure may weaken slightly the latter part the week with cooling spreading into the valleys Thursday...with slight cooling spreading farther inland on Friday and Saturday. Onshore flow will bring gusty west winds to the desert slopes of the mountains into adjacent desert areas each late afternoon through late evening.
SYNOPSIS FROM THE PHOENIX OFFICE
Strong high pressure will continue to build across the southwestern states early this week. This will result in record or near record temperatures at the hottest time of year. These temperatures will be extreme even by desert standards. A gradual decrease in the temperatures begins midweek, but excessive heat levels continue into next weekend.
