A warm storm moving through British Columbia this weekend is heightening avalanche risks, particularly during a period historically known for deadly avalanches in Canada. Environment and Climate Change Canada has forecasted precipitation, strong winds, and increased freezing levels across much of the province. Brian Proctor, a meteorologist from the weather agency, anticipates higher elevations to receive more snowfall over the weekend.

Avalanche peril is set to peak on Saturday in areas like the North Shore Mountains as freezing levels are projected to rise above 1,500 to 1,800 meters. The incoming storm may bring rain onto existing snow in mountainous regions, a combination that can elevate the risk of avalanches. Karina Bakker, a forecaster at Avalanche Canada, explains that new snowfall can consolidate, creating a cohesive mass that can trigger hazardous avalanches.

The current hazard is attributed to “persistent slab” conditions, where a layer of snow rests atop weaker snow buried deeper in the snowpack. Slab avalanches occur when the weaker layer gives way under the weight of the snow above, causing the entire slab to slide downhill. Forecasters warn that these buried weak layers make avalanches harder to predict as typical warning signs may not be visible.

March is historically a high-risk month for avalanches in Canada, with 69 avalanche fatalities recorded over the past 20 years. Bakker notes that March poses increased danger due to the complex evolution of the snowpack during winter, with multiple layers forming from varying weather conditions. Since December 2025, five avalanche-related deaths have occurred in British Columbia, emphasizing the importance of caution in backcountry activities.

Avalanche Canada advises individuals venturing into the backcountry to stay updated on daily forecasts and opt for conservative terrain choices. During elevated avalanche risks, it is recommended to stick to slopes under 30 degrees and avoid avalanche-prone areas entirely when the danger rating is high.
