Poor Air Quality Through Friday

It's Summer - What Makes This Heat Dangerous?

Poor air quality Wednesday through Friday as smoke from wildfires across the Boundary Waters & southern Ontario moves southwards across Minnesota & Wisconsin.

While heat indices in the upper 90s to near 100 are not all that uncommon in July, it’s the prolonged nature of this heat wave that can make it dangerous. Multiple days of these temperatures with little to no relief overnight can have a cumulative effect on heat stress, particularly for vulnerable individuals.
