In sintesi

Retreat to mellower terrain if you see signs of instability like cracking around your skis, feet, or sled.

Small, reactive wind slabs may not be sticking well to a hard layer underneath.

Avalanche Summary

No new avalanches were reported before 4 pm on Wednesday.

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

Snowpack Summary

10-15 cm of settling snow may sit over a frozen 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

Below this crust, a layer of facets or isolated surface hoar is sitting on another crust 50-100 cm below the snow surface. This layer produced surprising avalanches late in December in areas west and south of Pemberton. It seems like it was less active in this forecast area, and in general it seems to be gaining strength.

Overall, the snow depth remains shallow, ranging between 80 and 120 cm, decreasing rapidly below tree line.

Terrain and Travel Advice

  • Wind slabs may be poorly bonded to the underlying crust.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
