Points saillants

Overnight snowfall and gusty winds have formed fresh slabs. Expect to find the most reactive deposits around ridges or in loaded start zones.

    In areas that accumulate over 20 cm of fresh snow, slabs will be reactive to skiers. The touchiest areas will be around ridges and wind-affected terrain, and in pockets with deep depositions.

Avalanche Summary

No new avalanches have been reported recently.

If you head into the backcountry, please consider submitting observations and/or photos on the Mountain Information Network.

Snowpack Summary

10-30 cm of snow is forecast to accumulate by Saturday morning, falling with strong wind.

About 20 cm recent and settling snow covers a crust into the low alpine, and possibly higher. This crust formed around the new year, and it seems to be variable in thickness and strength across the forecast area. 50-100 cm down, a layer of facets or isolated surface hoar is sitting on another crust. This layer produced surprising avalanches late in December in areas west and south of Pemberton. Reports suggest it was less active in this forecast region, and also trending towards dormancy.

Overall, the snow depth remains shallow, ranging between 80 and 120 cm, and decreases rapidly below treeline.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • The new snow may require another day to settle and stabilize.
