Provincial officials are warning that wildfires in northern Manitoba could continue burning underground throughout the winter months, creating persistent environmental challenges even as snow covers the landscape.
The Hidden Threat Beneath the Snow
While surface fires have been extinguished, the province confirms that subterranean burning could persist in affected areas around Flin Flon and other northern communities. These underground fires, known as zombie fires, can smolder in peatlands and organic soil layers for months, hidden from view beneath winter snowpack.
The concern follows an intense wildfire season that left extensive damage across northern Manitoba forests. Evidence of the destruction was captured during a helicopter tour of the Flin Flon area on June 12, 2025, where charred trees and blackened landscapes revealed the severity of the blazes.
Understanding the Science of Winter Burning
Underground fires represent a particularly challenging aspect of wildfire management. Unlike surface fires that are extinguished by rainfall or firefighting efforts, these deep-burning fires can continue consuming organic material like peat and root systems beneath the surface.
"What makes these fires so concerning is their ability to survive winter conditions," explained a provincial wildfire expert. "The insulating properties of snow can actually help maintain the smoldering process, allowing fires to reignite when conditions become dry again in spring."
Long-term Implications and Monitoring
The persistence of underground fires poses several significant challenges for the region. Provincial officials have implemented ongoing monitoring programs to track these hidden blazes throughout the winter months.
Environmental scientists note that the situation in Manitoba reflects a broader pattern observed across Canada's boreal forests, where climate change is contributing to more frequent and intense wildfire seasons. The ability of fires to burn through winter represents an emerging concern for fire management agencies nationwide.
Residents in affected areas are advised to remain vigilant and report any signs of smoke or unusual ground heating, even during winter conditions. Provincial authorities continue to assess the situation and will provide updates as monitoring continues through the coming months.
