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
A trough of low pressure over the western states will bring stronger onshore flow...dry southwest to west flow aloft...and cooling into Tuesday with Tuesday high temperatures 5 to 10 degrees below average. Inland humidities will be lower with gusty southwest to west winds in the mountains and deserts. The marine layer will deepen with night and morning coastal low clouds and patchy fog extending into the far inland valleys for Tuesday and Wednesday. Low pressure will weaken over the western states for the latter half of the week with high temperatures returning to near average for next weekend with night and morning coastal low clouds and patchy fog extending into the western valleys.
SYNOPSIS FROM THE PHOENIX OFFICE
While a more few showers and thunderstorms will be possible across central and eastern Arizona today, a distinct drying trend will end storm chances across the lower elevations. Even higher elevation communities will see rainfall chances evaporate by Tuesday. Through the remainder of the week, mostly clear skies and dry conditions will prevail with temperatures hovering near or slightly below normal.
