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
Above normal high temperatures will continue through Saturday across the region, with inland northeasterly winds diminishing by this evening. Patchy low clouds and fog will return to portions of the coast tonight, with a greater coverage along the coast Friday night. Cooler Sunday, then a warming trend returns early to mid next week with weak offshore flow through the middle of next week

Building heights aloft and offshore flow will help high temperatures rise around 5 deg F above normal today. Gusty Northeasterly surface winds will surface below passes late this morning and early afternoon, then winds will begin to diminish later today as the offshore pressure gradient weakens. The ridge aloft and weak offshore flow will keep inland highs around 5 deg F above normal through Saturday, however highs will lower to near normal along the coast starting tomorrow as the marine layer redevelops from a coastal eddy

A weak low pressure system will continue to strengthen today along the south central Arizona, Mexican border. This system will circulate an increasing amount of moisture north into central and eastern Arizona, for a good chance of showers and thunderstorms. The low pressure system will begin to track northeastward tonight, moving toward the four corners on Friday. This will continue to produce unsettled conditions in central and eastern Arizona through Friday. Clearing skies with warmer temperatures are forecast to develop this weekend, through the middle of next week
