The Arizona Department of Environmental Quality has extended an air quality health watch through Sunday because PM-2.5 levels may exceed federal standards. A strong ridge of high pressure will produce possible record-breaking heat over the weekend. Mixed with strong morning inversions and light winds, pollution will remain trapped over the Valley.

Because of the health watch, the Maricopa County Air Quality Department will issue No Burn Day restrictions through Sunday midnight. The ban includes fireplaces, fire pits or open outdoor burning.

Particulate matter can aggravate existing respiratory issues such as asthma. It comes from either combustion (cars, industry, woodburning) or dust stirred up into the air.

To report an air quality problem or polluter, call (602) 372-2703, or file a complaint online at under the "contact us" tab.
