Wildfires in Alaska and Ontario are creating large quantities of smoke that is affecting not only those areas but Yukon, British Columbia, Quebec, Washington, Oregon, Idaho, and the Midwestern states. Tuesday morning the smoke is unusually noticeable in Milwaukee, Grand Rapids, Chicago, Detroit, Cleveland, and Toronto.
The NOAA map above shows the extent of smoke at 6:48 a.m. MDT July 9. The one below produced by the Canadian government is the forecast for 6 p.m. MDT July 10 but only covers the area within the black border.
