Smoke from Canadian wildfires is threatening air quality from the Midwest to western New York State, triggering warnings of “unhealthy” levels in some areas extending through the weekend.

Air quality alerts have been posted across Wisconsin and Minnesota as smoke from wildfires moves south, Zack Taylor, a senior branch forecaster with the US Weather Prediction Center, said in an interview. The pollutants could even spread to Iowa later Thursday, though forecasts suggest it won’t reach large East Coast cities such as New York for now, he said.
