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 later this week will lead to very hot temperatures over the weekend and early next week. A noticeable uptick in temperatures begins Friday. Then…temperatures really jump over the weekend…climbing well above normal on Saturday and several degrees hotter yet from Sunday through next Tuesday - reaching 115 to 120 degrees across the deserts each day! This would set new records Sunday and Monday at many locations. If you must be outside during the peak heat of the day, remember to stay hydrated! Drink before you get thirsty, limit your time outside/exposure to the sun, use your air-conditioner or seek out public locations that provide A/C like libraries, public malls, and cooling centers. Find a cooling center or hydration station near you at

An area of low pressure across the Pacific Northwest will keep temperatures across the region near to below normal through Thursday. Very strong high pressure will then gradually build across the Desert Southwest from Friday into at least the early part of next week, with record high temperatures likely at many locations

A low pressure trough along the West Coast will maintain a deep marine layer and cool days into Thursday, with areas of night and morning coastal low clouds and fog extending into the valleys. Building high pressure will bring much warmer weather and a shallower marine layer Friday through Monday. The warming will be very pronounced this weekend into early next week as high temperatures soar back above average, with the greatest increases over the valleys and deserts. A coastal eddy developing by Tuesday morning will bring cooler conditions west of the mountains, with hot weather continuing further inland
