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
Fair and hot weather will continue today. An increase in monsoonal moisture this weekend will increase the chance of showers and thunderstorms in the mountains and deserts each afternoon and evening. It will also be slightly cooler this weekend into early next week

Friday will be a transition day as heights begin to fall across all areas. Return monsoonal moisture will begin to encroach on our area as well, bringing a slight chance for afternoon and evening convection. Monsoonal moisture will make a more noteworthy push Sunday and Monday, with a plume of nearly 2" PW airmass riding north along the Baja coast and also across the Sonoran Desert. This airmass should be capable of generating heavy rainfall and possible flooding in the deserts and mountains on Sunday and/or Monday

Strong high pressure will once again keep thunderstorm activity somewhat isolated today as well as maintaining very hot temperatures. However, this high pressure system will begin to weaken starting Friday, with better moisture profiles streaming north throughout the region. In addition to somewhat cooler temperatures, a marked increase in thunderstorm activity will impact the area through the weekend and into the beginning of next week
