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
Another warm afternoon is expected today, before gradual cooling settles in during the second half of the workweek. The main concern continues to be the critical fire weather conditions in the mountains and deserts that will continue through at least Wednesday evening. Along the coast the marine layer will remain shallow today and tomorrow before increasing slightly late in the week

Troughing will continue to establish itself along the West Coast on Wednesday, with a second weak shortwave reinforcing the first and helping the trough retrograde westward. This should produce a weak closed low off the SoCal coast by Friday. For our local weather this will mean a slow cooling trend through the end of the workweek, and the continuation of gusty winds and low RH values in the mountains and deserts through at least Wednesday evening. Wind may actually be a bit stronger Wednesday evening, as a weak 700 mb jet reinforces mountain wave activity. RH values will likely recover some Thursday and Friday, but rapid moisture recovery is not expected

SYNOPSIS FROM THE PHOENIX OFFICE
Very warm and fairly dry conditions will last through Wednesday with lower desert highs around 110 degrees and only a slight chance of high terrain storms. A return of some minimal monsoon moisture looks likely for the latter half of the week resulting in mostly slight chances for showers and thunderstorms and slightly cooler temperatures. Some gradual drying this weekend will mostly confine storms to higher terrain areas of eastern Arizona with very minimal chances across the deserts
