The Wisconsin Department of Natural Resources has extended the

Air Quality Advisory until midnight tonight for the Northeastern Wisconsin Counties. Smoke originating from wildfires in Quebec, Canada continues

impacting PM2.5 concentrations at the surface across much of the

state. The air quality index is expected to range from the

UNHEALTHY FOR SENSITIVE GROUPS level to the UNHEALTHY level

across the advisory area. The highest concentrations are expected within the corridor south of a Minneapolis/St Paul, MN to Ironwood, MI line and north of a Dubuque, IA to Green Bay, WI line. It is recommended that

people with heart or lung disease, older adults, and children

avoid prolonged or heavy exertion, while everyone else should

reduce prolonged or heavy exertion.
