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
Low pressure off the Southern California Coast will continue a threat of showers and thunderstorms over the mountains and high desert areas into Tuesday. The low moves north and inland for drying, strengthening onshore flow, and a deeper marine layer for the latter half of the week. It will be noticeably cooler beginning Wednesday, and marine clouds will be more extensive each morning into the weekend. Patchy drizzle is possible west of the mountains Thursday and Friday mornings.
FROM THE PHOENIX OFFICE
Dry air moving into the region will end rain chances starting today while also bringing warmer temperatures through the middle of this week. A slight cooling trend is expected late this week into the weekend before a possible increase in moisture and a return to rain chances by Sunday into next Monday.
