A warm storm moving through British Columbia this weekend is heightening avalanche risks during a historically dangerous time in Canada. According to Environment and Climate Change Canada, the system will bring precipitation, strong winds, and rising freezing levels across much of the province. Meteorologist Brian Proctor noted that the increased snowfall at higher elevations over the weekend could lead to heightened avalanche danger, particularly in areas like the North Shore Mountains where freezing levels are anticipated to rise above 1,500 to 1,800 meters.
The forecast suggests that rain falling on existing snow in mountainous regions may elevate avalanche risks. Karina Bakker from Avalanche Canada explained that when new snow combines with existing snow, it can create a cohesive mass that increases the likelihood of dangerous avalanches. The current risk is attributed to “persistent slab” conditions, where a layer of snow rests above weaker snow buried deeper in the snowpack, making avalanches harder to predict.
March historically records the highest number of avalanche fatalities in Canada, with 69 deaths over the past two decades. Bakker highlighted the complexity of snow layers in March due to varying winter weather conditions, which can lead to heightened risks. Since December 2025, five individuals have lost their lives to avalanches in British Columbia, emphasizing the importance of staying informed on daily forecasts and choosing safe terrain when venturing into the backcountry during this critical time.
