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 PHOENIX OFFICE
Low pressure will linger across the region through tonight with a continued chance of showers and thunderstorms across south-central Arizona. High pressure will take over starting Thursday with temperatures climbing well into the 90s for both Thursday and Friday. Dry conditions will persist through the coming weekend into early next week while high temperatures fall back into the middle 80s to lower 90s.

SYNOPSIS FROM THE SAN DIEGO OFFICE
Marine layer clouds are likely to clear out of inland areas today while the beaches may remain mostly cloudy. Warmer today under higher pressure aloft. A little cooler on Thursday with better onshore flow as a low pressure system moves in over the Pacific Northwest. More significant cooling for Friday through the weekend with a deep marine layer producing night and morning stratus and patchy drizzle over and west of the coastal slopes with only partial clearing during the days. Strong onshore flow will create strong and gusty west winds in the mountains and deserts late Thursday through much of the weekend. Continued cool with a deep marine layer and gusty winds in the mountains and deserts early next week as a broad trough remains over the west coast.
