Avalanche Summary

No new natural avalanches were reported lately. Keep sharing your observations via the MIN; it helps strengthen our information gathering.

Snowpack Summary

At 1900 m, the snowpack ranges between 30 and 90 cm which is low for Early December. Windy areas, for example near Joffre Lakes, the alpine terrain is wind scoured and bare.

The upper snowpack has 15-25 cm sitting on a hard melt-freeze crust. In sheltered and shaded areas, surface hoar is growing at the surface. Thin snow depths and cold temperatures mean the lower snowpack is weakening. Early season hazards are expected to stick around.

Weather Summary

An arctic ridge of high pressure continues as the main attraction. Conditions will be dry until the pulse of snow, expected Wednesday night.

Tuesday NightDry, light southwest wind, temperatures in the negative teens near treeline.

WednesdayDry with snow starting late in the afternoon as a system approaches. Temperatures around -10 C, Light to moderate west to southwest wind.

Thursday

Snowy day with 5 to 15 cm accumulating under the influence of moderate southwest wind. Temperatures around -5 C near treeline.

Friday

Storm winding down with little to no snow, slightly cooler temperatures, light to moderate southwest wind, and a clearing sky.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Make observations and assess conditions continually as you travel.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Expect shallow snow cover that barely covers ground roughness.

Avalanche Problems

Wind Slabs

Lingering old wind slabs exist in a variety of aspects on lee features. With limited observations, uncertainty remains high for this problem.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
