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
Seasonal summer weather through Friday with high pressure over the Southwest. Weak monsoonal flow returns over the weekend with isolated thunderstorms over the mountains and deserts Saturday and Sunday. The monsoon strengthens Monday and Tuesday with greater thunderstorm coverage over the mountains. Some thunderstorms may drift west of the mountains into the inland valleys.
SYNOPSIS FROM THE PHOENIX OFFICE
Drier air over our region will result in a lower chance of storms for much of the work week. This will allow our warming trend to continue into Thursday with highs slightly above normal. Moisture begins increasing late Thursday and will usher in an increased chance of storms across the CWA Friday through the weekend. Subsequently, high temperatures decrease as well…most noticeably over south-central Arizona.
