Avalanche Summary

No recent avalanche activity has been reported.

Observations remain very limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network

Snowpack Summary

New snow will likely form new wind and storm slabs at the surface. This snow will bury a variety of surfaces, including old wind-affected surfaces, along with a chance of surface hoar or faceted crystals in wind-sheltered terrain.

A crust formed in early November is present in the lower snowpack, with possible faceted crystals above or below it. Large depth hoar crystals exist at the base of the snowpack, particularly in the northern part of the region.

Snowpack depth at treeline is about 100 cm, and most below treeline slopes are not yet at the threshold to avalanche.

Weather Summary

Wednesday Night

Cloudy with 5 to 15 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Thursday

Cloudy with 5 to 15 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Friday

Cloudy with 5 to 15 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature -12 °C.

Saturday

Cloudy with 5 to 15 cm of snow. 40 to 60 km/h southwest ridgetop wind. Treeline temperature -15 °C.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Make observations and continually assess conditions as you travel.
  • Be cautious of buried obstacles, especially below treeline.
