Potential increases in PM10 concentrations may increase to moderate or unhealthy level.

Imperial County Weather Synopsis
EXCESSIVE HEAT WARNING IN EFFECT UNTIL 8 PM PDT THURSDAY FOR SE CALIFORNIA & SW ARIZONA

SYNOPSIS FROM THE SAN DIEGO OFFICE
Excessive Heat through the Workweek. High pressure aloft over the Great Basin will create excessively hot weather through Friday. Temperatures will cool some over the weekend, but will remain above average. Hot weather will continue through the upcoming holiday weekend, but it will be cooler at the coast. Monsoon flow will bring a small chance of showers and thunderstorms mainly in the mountains during afternoons.
SYNOPSIS FROM THE PHOENIX OFFICE
Above normal temperatures will continue this week as strong high pressure remains firmly entrenched over the interior West. Thunderstorm chances will remain limited across lower desert communities through the rest of the week with activity focused mainly over mountain areas. However, areas of strong gusty winds are likely each afternoon and evening over the south-central Arizona deserts. The potential for cooler temperatures and increasing moisture improves across the region by the weekend.
