Department of Natural Resources officials say there could be air quality problems downwind of a northwestern Wisconsin wildfire.
The DNR issued an Air Quality Special Notice on Wednesday.
Agency spokesman Kevin Harter says they haven't had any reports of problems but residents in Bayfield and Douglas counties, where the fire has been burning, or counties directly to the south should be cautious.
The fire started Tuesday afternoon and has destroyed nearly 50 structures and forced dozens from their homes. Firefighters have stopped most of the fire from spreading as of Wednesday afternoon.
The DNR says people should monitor their symptoms and consult a physician if they have concerns about smoke exposure.
Symptoms include irritation of eyes, nose and throat, or breathing discomfort. Smoke can aggravate chronic lung or cardiovascular disease.
