|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
Fair weather will prevail this week. Night and morning low clouds and areas of fog will occur in coastal areas and western valleys, with lingering clouds along the immediate coast each afternoon. It will be warm inland and hot in the deserts, with a gradual cooling trend during the week. Temperatures will decrease slightly each day, but continue very close to seasonal averages through Thursday. Low pressure aloft will gently and gradually bear down on California this week. That will slightly deepen the marine layer to extend the coastal clouds farther inland during the latter half of the week. In addition, winds will increase during the afternoons and evenings in the mountain passes and portions of the deserts. The weather will turn coolest Friday and Saturday coming in several degrees below average.
SYNOPSIS FROM THE PHOENIX OFFICE
Little change in the weather pattern is expected through mid week as a strong high pressure system produces mostly clear, dry, and hot weather. However, a low pressure system moving through the western states will lead to a gradual cooling trend Thursday through Sunday. Anticipate more breeziness as well. During the latter half of this week and through the weekend, the ridge slowly gets pushed eastward and replaced by troughing from the Pacific. Accordingly, there will be a gradual cooling trend beginning Thursday with highs reaching 2-3 degrees below normal by Sunday. There will be some enhanced breeziness Friday and Saturday as well.
