Officials warned young children and those with respiratory illnesses to take precautions. For weeks, smoke from Canadian wildfires has been drifting across the border.

"A lot of the prairies within Canada, the prairie provinces, entered the fire season already starting out in a drought, and so there wasn't a lot of moisture throughout the winter," said Alex Jones a communications manager at the Canadian Interagency Forest Fire Center.

By the time the Silver State Hotshot crew arrived from Nevada a few weeks ago, Canada’s wildfires had already scorched millions of acres and shattered all-time burning records.

A Hazardous Weather Outlook is also in effect across the region. The National Weather Service issued the outlook because of smoke blanketing Wisconsin amid Canadian wildfires in Manitoba and Ontario. The smoke is being transported south by wind patterns, leading to air quality alerts and advisories across the state.

Considering wildfires, and prevailing winds blowing from Canada, are expected to become more frequent, the impact on crops will remain an area of study.

From 1982 to 1993, Canada’s median wildfire size was 112 hectares. From 2013 to 2022, it was 509 hectares. This year so far, it’s about 1,900 hectares.

The blazes have destroyed nearly 15 million acres of land, and the fire season is expected to go into September. With it comes the threat of smoky days in Minnesota and North Dakota.

Minnesotans are inhaling another plume of smoke from Canada this week, and an attempt to blame Canada's handling of wildfires is being met with eye-rolls north of the border. Why it matters: Experts say smoky summers are likely the new normal in Minnesota and many parts of North America unaccustomed to dealing with the haze as climate change turns the continent's forests into tinderboxes.
