Forest fires in northern Minnesota, adjacent portions of Ontario and Manitoba, and massive ones in the western US, combined with regional and local wind patterns to fill the Minnesota skies–and sometimes air–with smoke. Dim sunshine, milky-looking skies, and a strong “campfire” odor dominated portions of the summer.
Why is Minnesota smoky?
“We’ve seen many large and intense fires across western Canada that generate an enormous amount of smoke. Weather patterns can carry the smoke long distances and bring it south across the border. This produces adverse air quality impacts for Minnesota.”
Why is it so hazy in Minnesota?
Minnesota’s bad air in 2021 was largely the result of Canadian fires that were burning at the same time that an air mass was moving south from Canada into Otter Tail County, the meteorologists said.
What is causing the smoke in northern Minnesota?
Heavy smoke from Canadian wildfires has prompted the Minnesota Pollution Control Agency to expand an air quality alert originally for northern Minnesota to much of the state.
Where is the smoke coming from in MN?
Wildfire smoke can originate locally or travel into areas of Minnesota from other states, even other countries. In fact, in recent years, wildfires in Canada have been responsible for more “bad air” days than in-state sources. Air quality alerts should be taken seriously by everyone in affected areas.
Why is the air so hazy?
Haze is caused when sunlight encounters tiny pollution particles in the air. Some light is absorbed by particles. Other light is scattered away before it reaches an observer. More pollutants mean more absorption and scattering of light, which reduce the clarity and color of what we see.
Are there wild fires in Minnesota?
(Valley News Live) – The state of Minnesota experienced an extra hot and dry summer, leading to one of the most active wildfire seasons in recent history. The Minnesota Department of Public Safety says this summer, it responded to 17 wildfires between March and October 2021.
Should you stay inside wildfire smoke?
Protecting Yourself from Smoke
The best way to prevent breathing harmful particles in wildfire smoke is to stay indoors. When air quality reaches dangerous levels due to wildfire smoke, the most effective way to reduce exposure and avoid the ill effects of smoke is to stay indoors with windows and doors closed.
Can smoke in the air make you sick?
Inhaling fine particles can cause a variety of health effects, including respiratory irritation and shortness of breath, and can worsen medical conditions such as asthma and heart disease. During increased physical exertion, cardiovascular effects can be worsened by exposure to carbon monoxide and particulate matter.

What is haze vs fog?
Fog and haze are both weather phenomena of obstruction to vision. Fog is composed of a large number of tiny water droplets or ice crystals that suspended in near-surface air. Haze is a large number of tiny dry dust particles floating uniformly in the air[1–4].
How haze can affect your health?
Haze particles can sometimes affect the heart and lungs, especially in people who already have chronic heart or lung disease e.g. asthma, chronic obstructive pulmonary disease (COPD), or heart failure. There may be up to one to three days of time between exposure to haze and health effects/ symptoms.
What causes haze in winter?
Ample sunlight causes chemical reactions that are intense in mountain valleys during temperature overturns. Warm air traps the pollutants in the cold air. The contaminants are often made up of farm chemicals like ammonia.

Does air conditioning clean air of smoke?
It works extremely well to filter out particulates such as ash, soot, and other debris from nearby fires, and to neutralize the harmful gasses, chemicals, and odors that make up smoke.
Does drinking water help with smoke inhalation?
Drink a lot of water. Wildfire smoke inhalation causes microscopic particles to get trapped in your lungs. They can get into your bloodstream and travel throughout your body, contaminating your organs. Water helps flush these particles from your system.
Do bathroom fans help with wildfire smoke?
Don’t use bathroom fans and range hoods
First, indefinitely running an exhaust fan is a fire hazard. Second, if you’re constantly sucking air out of your home, that means you’re also pulling in smoky air through small gaps around the house.

The toxic components of tobacco smoke are found not only in the smoke that the smoker inhales but also in environmental tobacco smoke, or secondhand smoke—that is, the smoke exhaled by the smoker (mainstream smoke) and the smoke that rises directly from the smoldering tobacco (sidestream smoke).
