Air Quality Alert issued December 13 at 6:59AM MST by NWS Phoenix AZ

AQAPSR

The Arizona Department of Environmental Quality (ADEQ) has issued a
PM-2.5 High Pollution Advisory for the Phoenix Metro Area on Saturday.

This means that ongoing stagnant weather conditions combined with
existing airborne fine particulate levels may result in local fine
particulate concentrations that pose a health risk. Adverse health
effects increase as air quality deteriorates.

Fine particulate matter – also known as PM-2.5 – 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, reduce or eliminate fireplace use, refrain
from outdoor burning, and avoid using gas-powered lawn equipment.
