Smoke from large wildfires in Canada's Alberta province has drifted into many U.S. states, including Wisconsin, and is causing haze and air-quality issues.
Smoke from the wildfires cast hazy skies across several states Friday morning and was showing up on satellite. Besides Western states, Wisconsin, Illinois and Michigan were being affected.

More than two dozen fires are burning in Alberta, and 10,000 people have been forced from their homes.
The government agency Alberta Wildfire reports the largest blaze is out of control about 450 miles north of Edmonton and has burned 887 square miles of land.
The U.S. Environmental Protection Agency rated the air quality in Helena, Montana, as unhealthy Friday morning. The air quality in the Montana cities of Great Falls and Lewistown was rated as unhealthy for sensitive groups such as people with asthma or heart disease.
