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
Strengthening high pressure aloft will bring a warming trend into Friday or Saturday with high temperatures 5 to locally 10 degrees above average. This will be followed by slow cooling into early next week. The marine layer will become shallower with areas of night and morning coastal low clouds and fog extending locally inland

Most monsoonal moisture will remain to the east of southwestern California...though there will be some mid and high clouds at times and a few afternoon clouds near the mountains. Around Wednesday night...there may also be some higher level moisture and clouds from tropical cyclone Estelle...passing by well to the southwest

An increase in clouds and humidity can be expected during the next couple of days along with a slight chance of showers and thunderstorms, mainly east of the Lower Colorado River Valley. High temperatures over the central deserts will stay near seasonal normals, with hotter conditions over the western deserts. Storm chances on the lower deserts will be slight, with better chances over the higher terrain and over southeast Arizona. During the latter half of the week, storm chances will dwindle, and temperatures will increase to above normal levels.
