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 low pressure trough over California will weaken and move northeast on Wednesday, paving the way for high pressure and weak offshore flow Thursday through Sunday. This will bring warmer days and drier conditions with few marine clouds. A building south swell will bring elevated surf Friday through Sunday. Slightly cooler early next week as weak onshore flow develops..
SYNOPSIS FROM THE PHOENIX OFFICE
Above normal temperatures will return today and last through the weekend. There will be a slight chance of showers and thunderstorms across southeastern Arizona today and Thursday as low pressure slowly passes by to the north. However, most locations will see mostly clear skies and dry weather the entire week. Cooler conditions are likely early next week with temperatures dropping back to near normals.
