What is the air quality in Michigan? Advisory in effect because of Canadian wildfires
The air quality in Michigan continues to be evaluated as wildfires in Canada burn. Officials have issued an air quality advisory for counties across the Upper Peninsula.
"Overnight Sunday, a warm front tracks east into the Upper Peninsula of Michigan. Southwesterly winds will develop, bringing increased fine particulate to the northern portions of Michigan on Monday." according to MiAir division, part of Michigan's Department of Environment, Great Lakes, and Energy.
MiAir anticipates levels rising into the Unhealthy for Sensitive Groups range across the U.P. There is a chance hourly levels could reach the "unhealthy" range for a short time.
"As a result, we anticipate fine particulate levels rising into the Unhealthy for Sensitive Groups (USG) range across the Upper Peninsula. There is a possibility that hourly levels could reach the Unhealthy (red AQI) range for a short period of time."
The following counties are under an air quality advisory for elevated levels of fine particulate through June 2: Alger, Baraga, Chippewa, Delta, Dickinson, Gogebic, Houghton, Iron, Keweenaw, Luce, Mackinac, Marquette, Menominee, Ontonagon and Schoolcraft.
"24-hour daily average fine particulate concentrations will range between good and moderate, but unhealthy for sensitive groups (USG, Orange AQI) across the Upper Peninsula on Monday," the MiAir division said.
Sensitive groups include people with heart or lung disease, diabetes, older adults, children, and people of a lower socioeconomic status, based on the U.S. Environment Protection Agency.
In Canada, there are several priority fires ranging from roughly 9,100 to 306,000 acres in size. As of May 30, there were 77 uncontrolled active fires, according to Natural Resources Canada.
As the smoke continues to carry over, officials forecast the smoke to linger in Michigan.
"Extended models show a boundary moving into the region later Tuesday, lingering through the rest of the week. This boundary will trigger storm development. Air quality levels during this period will continue to be evaluated," the MiAir division said.
Here's more on the Canadian wildfires affecting Michigan:
An advisory is called when two or more (or widespread) monitors are expected to reach or exceed the Unhealthy for Sensitive Groups (USG, Orange air quality index (AQI) threshold.
An alert is called when two or more (or widespread) monitors are expected to reach or exceed the Unhealthy threshold.
Under an air quality advisory, sensitive groups can avoid adverse health reactions by staying indoors, turning on the air conditioning or wearing a N95 mask, according to the Cleveland Clinic.
Michigan residents can check current conditions through EGLE's MiAir Quality Index Dashboard. The interactive map provides AQI scores for cities across the state.
In addition, residents can use AirNow, a part of the U.S. Air Quality Index, and check local conditions by searching their ZIP Code or city. AccuWeather also has an AQI feature that lists the current pollutants in the air.
The AQI shows the outdoor air quality for public health. It features six color-coded categories, from good (0-50) to hazardous (301 plus).
On the AQI, a good reading (green) means the air is acceptable and residents may enjoy their outdoor activities; moderate (yellow) means the air is acceptable, however it could be harmful for specifically sensitive groups.

The AQI takes into account five air pollutants:
ground-level ozone
particle pollution (also known as particulate matter, including PM2.5 and PM10)
carbon monoxide
sulfur dioxide
nitrogen dioxide
Here are the ratings in the AQI:
According to Natural Resources Canada, the National Wildland Fire Situation Report says there are 77 uncontrolled fires; 25 being held; 47 controlled; and 25 modified response.
"Canada is at National Preparedness Level 5, indicating that there is full commitment of national resources and demand for interagency resources through the Canadian Interagency Forest Fire Center (CIFFC) is extreme. Since national availability of resources is limited, international resources are being mobilized," the Canadian department said.
The priority fires are located in Ontario, Manitoba and Alberta – with Saskatchewan and Manitoba in a provincial state of emergency.

'Similar to humans, animals are also affected when there are issues with air quality, especially birds, animals with underlying respiratory and heart conditions, and other sensitive populations — such as young or senior animals,' State Veterinarian Nora Wineland said. 'If animals are being negatively affected by breathing poor quality air, they could exhibit various signs of illness, including coughing, wheezing, having difficulties breathing, eye drainage, lethargy, changing the sound of their vocalization, decreased appetite, and thirst. For any concerns related to the health of your animals, please contact your veterinarian.'
To best protect animals from poor air quality, follow these tips:
Keeping animals indoors with doors and windows closed and limiting the amount of time they spend outdoors.
Avoiding strenuous activities/exercise.
Ensuring clean air flow when indoors by using fans, air conditioners, air purifiers, etc.

Sunny and warm weather today, rain chances increase into Sunday.
LANSING, Mich. (WLNS) — Mostly sunny skies are in the forecast however wildfire smoke will still be lingering across most of the area. Today will most likely be the pick of the weekend as high pressure remains in control of our weather. Skies start mostly sunny, with the smoke and haze from the Canadian wildfires, temperatures will be in the upper 70s. Eventually, clouds increase this afternoon and evening ahead of our next weather system. It looks like this system stays to our south but might clip close to the Stateline, Jackson and Hillsdale could see a shower or two late tonight into Sunday morning. Partly to mostly cloudy skies continue for most if not all of Sunday, temperatures remain warm into the mid 70s area wide. A cold front moves in late Sunday into Monday, this will be the best chance for most of Mid-Michigan to see widespread showers and even rumbles of thunder. Scattered showers and storms continue into Monday and even Tuesday as this low pressure system moves out of the Great Lakes. Temperatures warm back up by the middle of the week into the upper 70s to low 80s. Copyright 2025 Nexstar Media, Inc. All rights reserved.

One Million Drivers Told To Avoid Gas Stations
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Indiana residents are being advised to minimize visits to gas stations today as smoke from Canadian wildfires continues to worsen air quality across the state. The Indiana Department of Environmental Management (IDEM) has extended an Air Quality Action Day through Saturday; fine particulate levels are reaching unhealthy thresholds, particularly in northern, northeastern, and northwestern regions, as reported by WNDU, potentially affecting at least a million people. Newsweek contacted IDEM for comment via email on Saturday. Why It Matters EPA reports that Volatile Organic Compounds (VOCs) are chemicals that easily evaporate into the air and are released from sources like petrol stations, vehicle exhaust, paints, and industrial processes. At gas stations, VOCs escape during refueling and contribute to air pollution even with vapor recovery systems in place. When VOCs react with nitrogen oxides (NOx) in sunlight, they form ground-level ozone—a major component of smog, the United States Environmental Protection Agency reports. EPA advises that this ozone can aggravate asthma, trigger respiratory symptoms, and harm people with existing heart or lung conditions.

File photo: The price of gasoline is displayed on a pump at a gas station on March 6, 2025 in Chicago, To Know The smoke originates from over 200 wildfires burning across Canada, as reported by the Canadian Interagency Forest Fire Center, with plumes stretching thousands of miles and affecting air quality throughout the U.S. Midwest. In some areas, air-quality indexes have reached levels deemed "very unhealthy," prompting widespread advisories. Reducing vehicle emissions can help mitigate ozone formation during such alerts. Residents are encouraged to limit driving, avoid refueling vehicles during daylight hours, and postpone the use of gasoline-powered equipment. To reduce pollution and protect public health, it is recommended to avoid gas stations during air-quality alerts or refueling in the evening, when ozone formation is less likely. As reported by Newsweek, at least two people have died and tens of thousands have been evacuated in Canada as a result of the blazes. WDNU reported that the following cities in Indiana will be most affected by the air quality: North Central Indiana: Including the cities of Elkhart, Goshen, Knox, Logansport, Plymouth, Peru, South Bend, Warsaw, Winamac, and all other cities within the area. Northeast Indiana: Including the cities of: Angola, Auburn, Decatur, Fort Wayne, Hartford, Huntington City, LaGrange, Marion, Portland, Wabash and all other cities within the area. Northwest Indiana: Including the cities of: Crown Point, Gary, Hammond, Kentland, LaPorte, Michigan City, Portage, Rensselaer, Valparaiso, and all other cities within the area. IDEM has issued some recommended actions that the public can take. These include: Walk, bike, carpool or use public transportation. Avoid using the drive-through and combine errands into one trip. Avoid refueling your vehicle or using gasoline-powered lawn equipment until after 7 p.m. Turn off your engine when idling for more than 30 seconds. Conserve energy by turning off lights or setting the air conditioner to 75 degrees Fahrenheit or above. A National Weather Service (NWS) air quality alert said that fine particulate levels are expected to be in the Unhealthy for Sensitive Groups range. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exposure. What People Are Saying The American Lung Association warns that wildfire smoke poses significant health risks, especially for children, older adults, and individuals with respiratory conditions. They recommend staying indoors, using air purifiers, and keeping windows closed to reduce exposure. The American Lung Association stated on its website: "Areas throughout the Midwest, including parts of Indiana, will see their air quality impacted by smoke from wildfires burning in Canada this weekend. The smoke is prompting several communities to issue air-quality alerts. "It is unhealthy to breathe and can be especially harmful to sensitive groups, including children, older adults, and people with lung diseases like asthma and chronic obstructive pulmonary disease." What Happens Next Residents are advised to monitor local air-quality reports and take necessary precautions to protect their health during this period of elevated pollution.

Smoke expected to lift in northern Michigan, but more could be on the way
A smoky haze settled over Traverse City, as seen from the top of Copper Ridge Drive on June 26, 2023. Smoke caused poor air quality and hampered visibility across northern Michigan. (Photo: Ed Ronco/IPR News) This coverage is made possible through a partnership between IPR and Grist, a nonprofit environmental media organization. Canadian wildfire smoke that blew into the Great Lakes region is expected to clear from northern Michigan this weekend — at least for now. The Michigan Air Quality Division said Thursday morning that the heavy smoke across the Upper Peninsula was already clearing out. Earlier in the week, there were unhealthy levels of fine particulate matter in the air across parts of the Upper Peninsula and northern Michigan, with smoke settling here for days before moving further south. While division forecasters expect Friday to be the last day for advisories from this round of smoke, they said it was too early to put out a firm forecast much beyond that: 'There is still a considerable amount of smoke in Canada and the models are indicating a late weekend frontal system could draw down more smoke, next week.' The state has been issuing air quality alerts for much of the region. As of Thursday, there were still advisories across the Lower Peninsula for sensitive groups, including people with health issues like asthma. People can take measures to protect their health, such as limiting outdoor activities, closing windows, and running air conditioners with high-quality filters. This is the latest in a series of intense wildfire seasons fueled by dry conditions in Canada, resulting in smoky springs and summers in the Midwest. 'For the last few years, you've combined what has been somewhat persistent wildfire problems in Canada with an air flow that is moving some of that air from Canada down into the United States,' said Jim Keysor, a meteorologist with the National Weather Service in Gaylord. It can be difficult to predict how far-away wildfires will affect air quality in different regions, since smoke is influenced by factors like wind, pressure systems, weather fronts and geography. 'Wherever the wind blows, the smoke is going to go,' said Alec Kownacki, a meteorologist with Michigan's Air Quality Division. 'And at different levels of the atmosphere you can have differing wind directions.' Over the past week, low pressure systems funneled smoke from fires in the Canadian provinces of Saskatchewan and Manitoba toward the upper Midwest. 'Along with that wind shift, a cold front came through. And what happens on the back end of a cold front — you have a lot of air sinking,' Kownacki said. Local weather patterns also have an influence. While rain can help improve air quality, the rain that swept across parts of the region earlier this week actually pushed smoke down toward the earth, Keysor said, making exposure more likely. 'It's actually helping to bring down some of that smoke that's higher up into the atmosphere, which normally would have been way up there,' he said. 'That wouldn't have bothered us a whole lot.' One positive, Keysor added, was that modeling for smoke forecasts has become more accessible in the National Weather Service offices in recent years. Their smoke forecasts are informed by state data. 'The programmers that were putting some of those models together began to look at that [smoke] parameter a little bit more and to make it a product that we could view more readily,' he said. The weather models they use are improving. 'We're able to see more of it than we used to.' The heavy smoke that was hanging across the Upper Peninsula and northern Michigan has now moved further south, including around Lansing. 'It's wreaking havoc for us down here right now,' said Kownacki, who is based there. Conditions are expected to improve across much of the state over the next few days, but there may be more smoke from the fires in the near future. The state Air Quality Division updated its forecast on Friday morning.
