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
Warmer this week with strong high pressure building over the Southwest. The high stalls over Arizona next week, setting the stage for a long duration heat event from Friday through the middle of next week, perhaps longer. A shallow marine layer will keep the coastal areas cooler with areas of night and morning clouds and fog. Highs in the Coachella Valley and the San Diego Deserts will range from 110-115 Friday, and from 112-118 Saturday through Wednesday. Hottest days will be Monday through Wednesday when highs may reach 120 in a few spots.
Strong high pressure will build over the Desert Southwest the rest of this week and into next week. This will result in the first major heat wave of the Summer with high temperatures climbing well above 110 degrees in the lower deserts Saturday through Wednesday. In fact, many desert locations, including Phoenix, will reach 115 to 120 degrees Sunday through Wednesday. This heat is going to be extreme and should be taken with extreme caution. The Heat Risk will be high across our Arizona forecast area from Saturday through Wednesday and across our southeast California forecast area from Sunday through Wednesday.
