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
High pressure aloft will continue dry and very warm days inland this week, while the marine layer and weak onshore flow keeps areas near the coast cooler with areas of low clouds and fog. The fog will be dense at times and linger near the beaches into the afternoons. Slightly cooler by midweek as a weak low pressure trough weakens the ridge and increases onshore flow. Greater cooling is possible beginning Sunday as a low pressure trough approaches the California Coast with prospects for rain and mountain snow next week

SYNOPSIS FROM THE PHOENIX OFFICE
High pressure will dominate much of the western states this week. This will result in dry and unseasonably warm weather with only occasional high clouds. Anticipate the warmest day of the year so far to be on Saturday with highs in the middle 90s over the lower deserts.
