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
Warm and dry through early next week. Very warm for valley and coastal locations as gusty offshore winds continue into Thursday... weakening into the weekend. Expect daytime temperatures 10 to 20 degrees above seasonal averages. High temperatures will cool some for Friday into early next week...but remain above average

High pressure aloft will continue much warmer high temperatures for today with slight cooling for Thursday. Combined with weak to locally moderate offshore flow...this will push warmest high temperatures for inland coastal and western valley areas into the lower to mid 90s on Wednesday with high temperatures well into the 80s toward the coast. Surface high pressure over the western plains into New Mexico will bring periods of gusty east winds near the coastal foothills of the mountains into the valleys of San Diego and Riverside Counties and inland Orange County with the strongest and most widespread winds on today. Strongest gusts overnight have exceeded 40 mph...mostly in the coastal foothills and far inland valleys of San Diego County

SYNOPSIS FROM THE PHOENIX OFFICE
Upper level low pressure that will be backing westward into northern Mexico, just to the south of the New Mexico Bootheel will bring somewhat cooler temperatures and locally breezy to windy conditions to south central and southwest AZ today through Friday. A modest warming trend and continued dry conditions can then be expected from the upcoming weekend into early next week as high pressure rebuilds westward into the Desert Southwest
