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
Winds will range from north to northwest to west over the weekend, mostly light at 5 to 10 mph. Winds will likely increase Monday and into Tuesday.

WIND OUTLOOK: Another system moves through the Interior West on Monday and Tuesday. The main impact
will be windy conditions Monday into Tuesday (most noticeably for southeast CA and southwest AZ).

Some low clouds will persist into tonight west of the mountains before clearing out on Saturday morning. Dry and much warmer this weekend under a ridge of high pressure with weak offshore flow.

Saturday and Sunday will be sunny, dry and much warmer under a ridge of high pressure with weak offshore flow as a surface high moves into the Great Basin. Saturday will be the warmer of the 2 days with daytime temperatures in the 70s to low 80s west of the mountains. The offshore flow could produce local wind gusts to 45 mph in the mountain passes and coastal foothills, most likely on Saturday.

A little cooler on Monday with increasing clouds as the flow turns onshore in response to a low pressure trough moving inland to the north. Increasing low clouds west of the mountains could produce patchy drizzle in those areas on Monday morning.

A warming and drying trend is expected over the weekend as high pressure builds across the intermountain West. Early next week, a dry cold front will bring cooler temperatures and breezy to windy conditions Monday and Tuesday. Lingering breeziness will continue Wednesday and Thursday along with warmer temperatures.
