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.

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.

The residents of New York City were among the more than 132 million people in the country experiencing what the National Weather Service calls a "major HeatRisk," level 3 out of 4. The NWS and Centers for Disease Control and Prevention created the experimental HeatRisk tool to help assess possible health risks tied to extreme heat and humidity.

The Canadian government’s map of wildfire smoke fine particulate matter shows intense smoke over Saskatchewan and Manitoba, which then pushes out to Ontario, Quebec and Atlantic Canada through the week.

Montreal is grappling with the world's worst air quality due to wildfire smoke drifting from the Prairies, triggering health alerts across Quebec. Residents, especially vulnerable groups, are advised to limit outdoor activities as a heatwave exacerbates the risks of respiratory issues and heat-related illnesses.

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