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 mild weather will continue through Thursday as a trough of low pressure moves through the West. High pressure will build Friday and bring noticeably warmer weather through the middle of next week, along with some clouds over the interior. Coastal low clouds will be less extensive

the lower desert has their own version of a marine layer. A gulf surge, low level moisture coming from the Gulf of California, has produced morning low clouds there too. These will also clear out this morning. Plenty of monsoon moisture including the remnants of Javier will continue to pour into Arizona today, and the weather will be quite active for them. However for us, except for an isolated thunderstorm or two, we expect no precipitation on our side of the Colorado River. Our fair and coolish weather will continue through Thursday as a low pressure trough gradually moves through the western states. This trough will lift out and a high pressure ridge will build into our region Friday and Saturday. That will bring a noticeable warming trend, with temperatures rising several degrees above average Saturday through early next week, but some weakening in the ridge is shown by models next week. The monsoon moisture continues to float by mainly to our east this week and to our south next week. Guidance hints of some moisture for precip creeping northward into SoCal around the middle of next week, but not with enough certainty to forecast it yet.

Thunderstorm activity will continue intermittently over central and south central Arizona through Thursday as thicker moisture moves into Arizona. Any storms that develop will have the potential for strong winds and heavy rain. A warming and drying trend will begin Friday and continue through the weekend as high pressure builds across the region
