The Wisconsin Department of Natural Resources issued an air quality alert for all of southeast Wisconsin until noon on Monday, Aug. 4.

Last week, Canadian wildfire smoke blanketed Wisconsin and caused the Air Quality Index to reach the unhealthy level for sensitive groups. Six days later, on July 31, the smoke appears to have a worse impact on the air.

The smoky air is predicted to reach New York City on Monday, and it could bring unhealthy air quality for sensitive groups.
