Smoke from ongoing wildfires in Canada is spreading across parts of the Midwest and Great Plains, prompting air quality alerts in multiple states. Currently, over 90 uncontrollable fires are burning in Canada, particularly in Manitoba, leading to the evacuation of approximately 17,000 residents. Atmospheric winds have pushed smoke into the Upper Midwest as far south as the Georgia-Florida border.
Affected states are advised to consider limiting outdoor activities, especially for sensitive groups, including pregnant individuals, young children, the elderly, and those with respiratory or heart issues. Citizens may notice hazy skies and a campfire scent, with vibrant sunrises and sunsets reported. In Minnesota, a state-wide air quality alert is in effect until Monday evening, with northern counties experiencing unhealthy air conditions. Even those not in sensitive groups may encounter health effects like itchy eyes and coughing due to high pollution levels.
Wisconsin issued a temporary air quality advisory that could be reinstated given worsening conditions. North Dakota’s air quality has reached a “very unhealthy” status, prompting officials to warn residents, especially those with respiratory conditions, to minimize outdoor exposure. South Dakota also has air quality alerts in specific areas until conditions improve.
The wildfire smoke poses health risks far beyond the fire’s immediate vicinity, having previously affected major cities in the Northeastern U.S. Fine particulate matter from the smoke can lead to serious health issues, including increased risks of cardiac arrest and stroke after short-term exposure and chronic diseases with long-term exposure. With climate change making wildfires more frequent and severe, these events coincide with extreme weather patterns elsewhere, including heat waves and storms in other parts of the country.
