Smoke Spreads Across Ontario

Smoke Spreads Across Ontario

A cluster of lighting-triggered fires has burned in Canada along the Ontario and Manitoba border since early July, sending thick plumes of smoke streaming across Ontario. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured an image of smoke darkening skies as far south as Minnesota, Wisconsin, and Michigan on July 7, 2019. Wildfire smoke triggered the evacuation of hundreds people from a village in Northwest Ontario and prompted air quality warnings in Winnipeg and the United States, according to news reports.
