    Ongoing snowfalls and wind will keep developing fresh wind slabs. These will be reactive to riders, especially near alpine ridges and cross-loaded features.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

No new avalanches were reported, but observations remain limited.

If you are heading into the backcountry, please consider sharing your observations via the Mountain Information Network.

Snowpack Summary

Trace amounts of wet snow have fallen in upper elevations on Saturday morning, while rain has transformed the surface into soft, moist snow at treeline and below.

This overlies a variety of surfaces, including a crust on south-facing aspects and wind-affected snow on north-facing terrain.

The mid-December crust is 150 to 250 cm deep. This crust is 30 cm thick and well-bonded to the snow above.

In general, the snowpack is well settled and right-side up.
