Smoke from wildfires in Canada is causing widespread air quality alerts across the Midwest and Great Plains. Currently, over 90 uncontrolled wildfires are burning in Canada, particularly in Manitoba, leading to the evacuation of around 17,000 people. Atmospheric winds have pushed smoke southeast, affecting states as far as the Georgia-Florida border.
Air quality is compromised in several states, with sensitive populations—including pregnant individuals, newborns, the elderly, and those with respiratory or heart issues—advised to limit outdoor activities. Residents in impacted areas may notice a campfire odor, hazy skies, and colorful sunsets, as reported by the National Weather Service. Minnesota has issued a statewide air quality alert until Monday evening, with northern counties facing unhealthy air conditions according to the Environmental Protection Agency’s Air Quality Index (AQI). Symptoms may include itchy eyes, coughing, and shortness of breath even among those not typically sensitive to air pollution.
Wisconsin had a temporary air quality advisory that may be reinstated, particularly for its northwestern regions expected to experience heavy smoke. North Dakota is currently facing “very unhealthy” air conditions, prompting state officials to caution residents to limit outdoor activities. South Dakota has also issued an air quality alert for certain areas.
The occurrence of smoke from Canadian wildfires has implications beyond immediate surroundings; it can affect air quality hundreds or even thousands of miles away, increasing health risks associated with fine particulate matter. These wildfires reflect a troubling trend of escalating frequency and intensity due to climate change, coinciding with other extreme weather events across the U.S.
