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
Monsoonal moisture will continue a chance for afternoon thunderstorms in the mountains and deserts through Wednesday and possibly Thursday. A trough of low pressure near the West Coast toward the end of the week will bring drying of the monsoonal moisture with lower inland humidities. Near to slightly below average high temperatures will begin slowly warming for inland areas next weekend

Southwestern California will remain on the western edge of monsoonal moisture through mid week. Model forecasts show slightly lower precipitable water values today versus Sunday...a little more for Tuesday into Wednesday...then drying into Thursday. This monsoonal moisture will continue a chance for afternoon thunderstorms in the mountains and deserts through Wednesday and possibly Thursday. Isolated to widely scattered thunderstorms are expected this afternoon and again Tuesday afternoon...mainly near the mountain ridge tops onto the desert slopes of the mountains...and in portions of the deserts north of the San Bernardino Mountains with isolated flash flooding possible

SYNOPSIS FROM THE PHOENIX OFFICE
A very humid monsoon airmass over the region will increase the chance of showers and thunderstorms region wide through Wednesday. Later in the week, drier westerly flow coming off the Pacific will push the chance of showers and thunderstorms into eastern Arizona. Warmer temperatures are forecast later in the week and weekend.
