The smoke from Canadian wildfires produced some of the worst fine particle pollution on record in Minnesota over the weekend. The Minnesota Pollution Control Agency released the top hourly fine particle readings from the air quality alert that ran from Friday to Sunday, with the worst reading reaching 404.9 in Detroit Lakes.

The Dragon Bravo Fire has destroyed dozens of structures and a water treatment facility, and the White Sage Fire, located in Kaibab National Forest, has forced hundreds to evacuate.

Wildfires continue to burn in Canada, and the smoke is filling communities there and towns across the U.S. border.

Air quality across Minnesota was pretty bad this past weekend. It was so bad that it was ranked as some of the worst in the world!

The amount of land burned this year is on pace to be the most since 1994, as 100 blazes roared on Friday across the central Canadian province.

An air quality alert is in place for the entire state of Minnesota through 9 a.m. Monday. Northern Minnesota falls in the very unhealthy AQI category.

As winds shift back out of the south, the Canadian wildfire smoke blanketing the metro is expected to improve throughout the day on Sunday. However, some air quality issues will still persist, especially in northern Minnesota. An air quality alert remains in effect for all of Minnesota until 9 a.m. Monday.
