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
Areas of gusty westerly winds in the mountains and deserts will diminish this morning as areas of northeast winds develop through and below mountain passes and foothills. Fair and seasonal weather is expected this coming week, but with more clouds again Saturday and Sunday mornings. Less cloudiness and slightly warmer weather next week

Low clouds fill the coastal basin up the coastal slopes to about 5000 feet this morning. At the same time variable high clouds continue to drift higher overhead. The strong westerly onshore winds in parts of the mountains and deserts will diminish this morning. Offshore flow will develop today, but will not amount to much. Some gusts below Cajon Pass are forecast to 30 mph or less heading into eastern Orange County. Even weaker winds below other mountain passes and foothills. The breath of offshore flow will help the low clouds clear across the region, but won`t be a big flush of dry air like recent offshore episodes have been. Fair weather with variable high clouds will continue, with little if any low clouds Thursday and Friday. Our weather pattern for the coming week doesn`t change much.

SYNOPSIS FROM THE PHOENIX OFFICE
A weak storm system will pass to our north through Wednesday helping increase thicker clouds and cool temperatures slightly. Dry weather with seasonably comfortable temperatures and occasional passing high clouds will return Thursday and continue through the weekend.
