This was 3 days ago: Health officials are encouraging residents to tele-work, carpool or
use mass transit during the advisory period.
- Residents are also advised to avoid outdoor exercise during the day, delay refueling vehicles until the evening, and postpone painting or cleaning projects that use volatile organic compounds.
The AirNow interactive map shows parts of Arizona edging
into the "purple" category of air quality, indicating very unhealthy
conditions.
- Localized spikes in PM10, which are inhalable particles less than 10 micrometers in size, such as dust, were detected in western Pinal County, but experts caution that readings may not reflect broader regional trends.
Meanwhile, ozone levels in Phoenix are forecast to remain in the mid-to-upper range of the Moderate Air Quality Index (AQI) category.

. . .While a low-pressure system expected over the weekend may reduce ozone
formation, the system is also forecast to bring stronger winds that
could increase airborne dust levels.
An ADEQ spokesperson told Newsweek:
- "This week, air pollution around Arizona will be primarily locally driven.
- Therefore, PM10 (dust) and PM2.5(smoke) will generally be highest in the mornings/evenings, when local activity is greatest during times of stagnation."
The statement added:
"Ozone is expected to be elevated in Phoenix each day this week, at most in the mid-upper range of the Moderate Air Quality Index (AQI) category.
Light winds and mostly sunny skies will be favorable conditions for the local formation and build-up of ozone."
