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
Thunderstorms developed in Los Angeles at about 345 am and moved into northern Orange County just before 4 am. We updated the forecast to add isolated thunderstorms for Orange County and the northern Inland Empire. The thunderstorms lasted only about 20 minutes and went away just as fast as they sprang up. Still can`t rule out an isolated thunderstorm for this little region this morning, but they are not very likely

Periods of rain will come and go this week along with some strong winds in the mountains and deserts. The first rain will move through the region this morning. The next rain will arrive late Tuesday and continue Wednesday. A third rain event will arrive Thursday. Dry and cool offshore flow will develop this weekend

SYNOPSIS FROM THE PHOENIX OFFICE
Moist Pacific flow will allow periods of thicker high clouds to stream across the Southwest through the middle of the week. A few sprinkles or very light showers will be possible today though most locations will remain dry. Otherwise, temperatures will hover in a slightly above average range through mid-week. A stronger storm system may begin to affect the region by the latter half of the week with showers and much cooler temperatures.
