|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
|At 9 am PST, water vapor satellite imagery displayed an upper-level trough moving southeast over central Baja, two upper-level lows off the PAC NW, and NW flow aloft over southern California. Surface observations showed gusty westerly winds diminishing over the mountains and deserts. The Wind Advisory will be allowed to expire at 10 AM. A PNS was issued with the highest observed wind gusts for the past 48 hours, and is headlined on our webpage. Northwest flow aloft will continue below normal high temperatures, fair weather and a few high and low clouds at times through Saturday.
SYNOPSIS FROM THE SAN DIEGO OFFICE
Fair and cool weather will continue through Saturday. A few disturbances could generate rain, mountain snow and gusty winds at times Sunday through early Tuesday. Dry and warmer weather with possibly breezy offshore winds is expected for the middle of next week.
SYNOPSIS FROM THE PHOENIX OFFICE
Behind a cold front, temperatures will hover slightly below average through the remainder of this week and into early next week. Two fast moving storm systems will move into the region Sunday and again on Monday. The weather system on Monday will have the better potential of spreading rain showers across much of the region. Drier and eventually warmer weather will return to the area by the middle of next week
