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
Strengthening high pressure aloft will bring a summertime heat wave inland through the weekend. Coastal clouds will be patchy during nights and mornings. This will be followed by cooler but more seasonally warm weather next week

A patch of high clouds over the desert and a patch of low clouds around San Diego were all that blemished the sky this morning. Both patches are going away and, except for a few cumulus over the mountains, skies will be sunny today. The hot weather from yesterday will continue today and become a little hotter Friday as a strong high pressure ridge over Texas expands west over SoCal

SYNOPSIS FROM THE PHOENIX OFFICE
The dry weather across southeast California and southwest Arizona will begin to spread eastward, with the chances for showers and thunderstorms gradually dwindling across central Arizona the next several days. The combination of thinning moisture and a much warmer atmosphere building into the region, will cause afternoon temperatures to soar, especially Friday and Saturday. Temperatures will cool a bit Sunday, but still remain fairly hot into next week, as thunderstorm chances return to the forecast
