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 PHOENIX OFFICE
A large region of low pressure will continue over the Western States through the weekend. There will be day to day fluctuations in temperatures and afternoon breeziness as the system waxes and wanes. Overall though, temperatures will remain below normal and conditions will remain dry

Relatively cool airmass in place this morning with lower desert locations mainly starting out the day in the upper 50s to middle 60s. Dry atmospheric profiles and no clouds in sight on satellite will provide for a clear day today. The nearly stationary low pressure trough over the Western United States will keep temperatures from reaching normal highs in the middle 90s today and likely through the rest of the week. No changes to the current forecast are needed.

SYNOPSIS FROM THE SAN DIEGO OFFICE
A trough of low pressure over the western states will strengthen a little through Wednesday...then weaken again for next weekend. High temperatures will remain below average for inland areas through much of the week...then warm towards the end of the week into next weekend. A deep marine layer will bring areas of night and morning low clouds and patchy fog for coastal areas inland to the coastal mountain slopes. There are small chances for light precipitation along and west of the mountains for late tonight into Tuesday morning and again late Tuesday night into Wednesday morning with a slight chance of thunderstorms near the mountains Wednesday afternoon. There will continue to be periods of gusty west winds in the mountains and deserts...stronger during the late afternoon and evening each day
