Air Quality Alert issued January 7 at 12:13PM MST by NWS Tucson AZ

The Arizona Department of Environmental Quality (ADEQ) has issued an
Coarse Particle – for Wind/Dust (PM10D) High Pollution Advisory for
the Rillito (near Marana) Wednesday.

An episode of strong and gusty winds is forecast to generate
widespread blowing dust that may result in local PM-
10 concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.

Coarse particulate matter – also known as PM-10 – is an air
contaminant that can aggravate heart and lung disease conditions,
especially in older adults, children, and those with asthma. A
decrease in physical activity is recommended.

Consolidate your travel, stabilize loose soils, slow down or avoid
travel on dirt roads, reduce or eliminate fireplace use, and avoid
using gas-powered lawn equipment.
