Canadian wildfires led to Mackinac Bridge in Michigan being shrouded in smoke, prompting visibility and air quality concerns, with Michigan authorities and health officials advising caution and monitoring air conditions.

A pulmonologist recommends limiting outdoor exposure to minutes when AQI exceeds 150, and notes smoky conditions from Canadian wildfires could last for weeks.

Lightning, which is more common in hotter temperatures, is usually the cause of wildfires that burn the most land. In 2023, scientists at Canada’s natural resources department found that lightning sparked fires that burned 93 percent of the total wildfire area, and the remaining seven percent of the area burned from human causes.
