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
The ridge over the Southwest will flatten today and Thursday as a trough of low pressure moves across the Pacific Northwest. This should result in minor cooling in most areas. As a result, the Heat Warning for the mountains has been cancelled.

Very strong high pressure sprawling across the southern United States will bring continued hot weather to the area with lower elevation locations reaching highs generally between 110 and 115 degrees. The above normal temperatures will persist through next week as high pressure becomes re-established across the desert southwest. The monsoon high will also bring a slight chance of showers and thunderstorms to the desert southwest next week

Weakening high pressure aloft and increasing onshore flow will allow the marine layer to build slightly through the week. Night and morning low clouds and fog will return to the coast and western valleys, while mostly clear and warm weather prevails farther inland. The high pressure aloft will still keep the weather warmer than average through Saturday. Hot weather returns again early next week as the high aloft rebuilds over the region
