Kernpunkte

If we receive as much snow as forecast, travel in avalanche terrain is not recommended. As snow accumulates, the avalanche danger in the mountains will intensify.

    The severity of the problem will depend on the actual amount of snow received. As the day progresses, the storm slab problem will become more pronounced. In alpine terrain and at treeline, snow is expected to accumulate more on north-facing aspects due to extreme southerly winds. As temperatures will hover around 0 °C, the snow will likely be heavy and therefore more reactive to rider traffic.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.
  • We are uncertain if precipitation will fall as rain or snow.

Avalanche Summary

Storm slab avalanches up to size 2, along with signs of instability, were reported at Mines Madeleine on Friday at treeline on northeast aspects.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

By Sunday evening, we could receive between 15 and 30 cm of new snow. This snow will fall on a variety of surfaces: wind-affected snow, powder, and sun crust.

A widespread melt-freeze crust about 2 cm thick is present at depths of 40 to 90 cm. A weak layer of faceted grains has developed on this crust on north to east aspects and is reactive in tests at treeline and in alpine terrain.

At mid-elevation, the average snowpack depth is around 140 cm.

Weather Summary

Sunday: Snow at times heavy mixed with ice pellets. Accumulation of 15 to 25 cm. Risk of freezing rain late in the afternoon. Southeast wind at 70 to 100 km/h. High of -2 °C. Freezing level rising to 450 m overnight into Monday.

Monday: Cloudy. Accumulation of 1 to 5 cm. Northwest wind at 20 to 40 km/h. High of +1 °C in the morning, then cooling to -7 °C in the afternoon.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be aware of the potential for human triggerable storm slabs at lower elevations, even on small features.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
