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
A deepening trough over the West will bring a cooling trend and more marine layer clouds through Friday. On Saturday the flow turns offshore as high pressure builds. That will bring Santa Ana conditions, clear skies and hot weather next week.
SYNOPSIS FROM THE PHOENIX OFFICE
Warm conditions will continue today as a weak disturbance approaches from the west. This will bring a slight chance for very light showers over south central Arizona Thursday morning, but will quickly move out of our area by late Thursday afternoon. A cooler airmass will settle in over the weekend before high pressure returns, sending temperatures well above normal by early next week.
