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 and offshore flow will strengthen Friday and continue Saturday. This will bring warmer and dry weather. It will also produce areas of strong northeast winds in foothills and some inland valleys. Cooler weather arrives Sunday as onshore flow returns, but flow will turn offshore again Monday and continue through Wednesday. That will bring warmer weather again along with areas of strong northeast winds.

SYNOPSIS FROM THE PHOENIX OFFICE

Above normal temperatures will continue today and last through the weekend. There will be a slight chance of showers and thunderstorms across southeastern Arizona today 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 seasonal normals.
