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
IMPERIAL COUNTY
Partly cloudy today. Light northwest to north winds will increase slightly during the night. Highs will be in the low 70s.

SYNOPSIS FROM THE SAN DIEGO OFFICE
A weak low pressure system will move out this morning and offshore flow will develop today. The offshore pressure gradient tightens up overnight for more widespread offshore winds, strongest in the coastal foothills.
Gusts in these favored areas could exceed 35 mph tonight into Friday morning. The winds decrease quickly during the day. Dry and fair weather will result through the weekend.

SYNOPSIS FROM THE PHOENIX OFFICE
A weather system moving east across the region is expected to bring lingering isolated to scattered showers to south central Arizona today; showers will continue to decrease tonight into Friday and mainly affect higher terrain areas to the east of Phoenix. High temperatures today will be on the cool side with central deserts only reaching into the middle 60s. A warm up is expected this weekend followed by another potential weather system for the first half of next week. The system next week will likely bring cooler temperatures along with at least a few showers to portions of south central Arizona.
