Moderate Air Quality Awakens: What West Pinal Can Expect

West Pinal is set to experience moderate air quality through the end of the week as the arrival of the monsoon season begins to take shape. Initial forecasts show that Monday and Tuesday will see particulate matter (PM₁₀) remaining in the moderate range, while fine particles (PM₂.₅) and ozone levels will be classified as good.

Weather patterns suggest that by Wednesday, storm activity may increase, with PM₁₀ levels peaking at an Air Quality Index (AQI) of 94. Additionally, evening conditions may lead to blowing dust as moisture from northern Mexico combines with a low-pressure system moving in from the west.

As the week progresses into Thursday, forecasts predict drier conditions, contributing to an improvement in AQI levels. Throughout this period, ozone levels are expected to remain stable, fluctuating between good and moderate.

This marks the first notable indication of monsoonal weather affecting rural Pinal County, particularly with storm chances concentrated in higher elevations.
