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
Today will be mostly sunny except for some patchy coastal fog and some increasing high clouds. It will be cooler Friday as the marine layer deepens in advance of a low pressure trough moving into California. The trough will bring showers along with strong winds in the mountains and deserts Saturday. Weak high pressure will return next week bringing fair weather.

SYNOPSIS FROM THE PHOENIX OFFICE
High pressure over the region will result in high temperatures in the 90s today and Friday. A Pacific low pressure system will begin to take shape this weekend over northern California, and will
result in strengthening wind speeds on Friday and especially Saturday. A slight chance of showers will also exist on Saturday evening as a cold front moves through the region. Much cooler temperatures are expected by Sunday, before another warming trend into next week as high pressure rebuilds across the Southwest.
