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
Marine layer clouds west of the mountains this morning will be slow to clear back to the coast this afternoon. The marine layer will turn shallower through Sunday as high pressure aloft builds over the Southwest. This upper ridge will remain nearly stationary through the middle of next week resulting in an extended period of hot weather.
SYNOPSIS FROM THE PHOENIX OFFICE
Slight chances for showers and thunderstorms will linger across central and eastern Arizona today, but decrease Friday as drier air moves in from the west. Sunny and hot temperatures can be expected across the region this weekend. A modest increase in moisture levels early next week will mean a return of slight chances for rain, possibly stretching all the way into southeast California. Temperatures will cool a few degrees in response to the moisture.
