Smoke from wildfires in Manitoba, a Western province facing its worst fire season in 30 years, has created hazardous air quality conditions across Eastern Canada and the United States.

The Cram fire is the largest in the state, expanding overnight to more than 64,000 acres, according to the Northwest Interagency Coordination Center. It is zero percent contained, while the Elk fire in Klamath is 39% contained and has burned around 2,700 acres.
