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
IMPERIAL COUNTY
Cooler temperatures with some breeziness is on tap for Friday. The breezy conditions should be replaced by light northwest winds through the weekend. After cooler temperatures on Friday, there will be warming through the weekend.

SYNOPSIS FROM THE SAN DIEGO OFFICE
After a cool start this morning, expect a fair and mild day with light winds. Warm and dry weather returns this weekend as high pressure builds over the West, accompanied by Santa Ana conditions. Gusty offshore winds will quickly drive any left-over marine air offshore on Saturday morning, leaving very low humidity and warm days through Monday. Strongest winds will develop along the coastal foothills, and through favored passes and canyons. Somewhat cooler mid next week as the high pressure aloft weakens and weak onshore flow returns.

SYNOPSIS FROM THE PHOENIX OFFICE
A weather system passing north of area will bring some breeziness to SE California along with modest cooling to all areas today. A warming trend will quickly begin Saturday with high temperatures nearing record levels in the 80s Sunday and Monday. High pressure gradually weakens thereafter allowing temperatures to cool, although still remaining above average.
