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
SYNOPSIS FROM THE SAN DIEGO OFFICE
A shallow marine layer will bring areas of low clouds and dense fog near the coast this morning. High pressure aloft and some offshore flow will continue to bring warm weather inland today. A gradual cooling trend will occur Sunday through Wednesday as the high pressure aloft weakens and an upper low forms off the coast. Night and morning low clouds will gradually become more extensive west of the mountains. Light rain is possible west of the mountains Tuesday morning, with more significant precipitation possible across the region next weekend as a deep trough of low pressure covers the West Coast.

FROM THE PHOENIX OFFICE
High pressure will subside late this weekend resulting in a gradual cooling trend starting Monday. Afternoon highs in the lower and middle 90s will be common for lower elevation communities this weekend with highs falling into the 80s during the early and middle parts of next week. Dry conditions are forecast to persist with little chance of rain through the end of the month.
