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
Fair and warmer weather is expected as weak low pressure aloft covers the West. Areas of low clouds will appear near the coast nights and mornings. Warmer weather will arrive Sunday and Monday as high pressure strengthens. Moisture from the south will bring a slight chance of thunderstorms to the mountains during the afternoons Monday and Tuesday. A trough of low pressure will bring cooler weather toward the middle of next week

SYNOPSIS FROM THE PHOENIX OFFICE
Sunny skies will dominate our weather the next few days at least

Temperatures will be increasing a little each day and up to seasonal averages by Saturday. On Sunday the cut off low will move into northern Baja Mexico and allow a high pressure ridge to nose into California from the west. This will also direct some northeast flow on the west side of the low that will create some offshore winds in our foothills Sunday and Monday mornings

The cutoff low will also draw northward some moisture from southwest Mexico. Models are coming into a better consensus on some of that moisture moving into Southern California Monday through Tuesday
