Winter Storm Warning Risk in Whitehorse, Yukon
Whitehorse sits deep in Canada's subarctic interior, where long winters and reliably cold temperatures define the season. Across the 13 years analyzed from 2012 through 2024, the city averaged 142.1 cm (55.9 inches) of snowfall annually — a substantial total that arrives gradually rather than in dramatic bursts. The snowiest stretch of the year runs through November, December, and January, when cold air masses settle over the Yukon and persistent snowfall steadily builds the seasonal snowpack.
Despite that respectable annual total, true heavy-snow events are surprisingly rare. The data shows an average of just 0.1 heavy-snow days per year, and major snow days effectively do not occur here. Winter storms in Whitehorse tend to be slow, sustained affairs rather than high-intensity events. Average winter overnight lows sit around −15.6 °C (3.9 °F), meaning that even modest snowfall can become dangerous when combined with extreme cold and blowing snow reducing visibility.
A winter storm warning in Whitehorse is typically issued when snowfall, blowing snow, or a combination of hazardous conditions reaches thresholds set by Environment and Climate Change Canada — thresholds that differ from those used in southern Canada or the United States. What qualifies as a warning-level event varies significantly by region, so local forecasts and official alerts should always be your first reference before traveling in winter conditions.
