Unhealthy air warnings in large areas of the US
Dense smoke from more than a hundred wildfires burning in Canada and Minnesota is moving southeast this week, affecting millions of people in the north-central and northeastern regions of the United States. Alerts for dangerous and unhealthy air quality extended Wednesday from Minnesota, through Toronto, to New York.
Added to this are unusually high summer temperatures. Tyler Hasenstein, a meteorologist with the National Weather Service in Chanhassen, Minnesota, warned:
“For those two things to coincide is not good from a health perspective.”
The best advice, he said, is to stay indoors to avoid both smoke and extreme heat.
Evacuations in the Boundary Waters Wilderness Area
In far northeastern Minnesota, game wardens are working to evacuate between 6,000 and 10,000 people still remaining within the Boundary Waters Canoe Wilderness Area. The 445,000-hectare area (almost the size of Delaware) was closed Tuesday due to about 17 lightning-caused fires. Access is only possible by canoe.
Joy VanDrie, spokesperson for the Superior National Forest, explained:
“It’s hard work.”
Rangers and campers must paddle for hours or carry their boats overland to get out. VanDrie did not say when the area might reopen. Minnesota officials will allow some fires in the Boundary Waters to continue burning under monitoring, as long as they do not threaten people or property.
Additionally, the Canadian Air Force on Wednesday rescued two groups of young campers who had crossed the border and were safe, according to Minnesota Governor Tim Walz.
The smoke is expected to persist for several days. The authorities recommend that the population stay informed and avoid outdoor activities.
