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
A trough over the Western U.S. will keep temperatures below seasonal averages through Tuesday along with a deep marine layer west of the mountains. Warming will occur during the second half of the week as the trough lifts out and a weak high pressure ridge builds into the area. A building south swell will bring elevated surf beginning Thursday into the weekend.
Above normal temperatures will return today along with a gradual warming trend through the week. There will be a slight chance of showers and thunderstorms across southeastern Arizona during the midweek period as a southwesterly flow develops between a building area of high pressure and a persistent low pressure area. However, most locations will see mostly clear skies and dry weather the entire week. Somewhat cooler conditions are possible early next week as the high shifts west of the region into the eastern Pacific.
