Lo esencial

If you venture out in the cold, even a small issue can become a big problem.

Avalanches are of greatest concern in areas with a transition from shallow to deep snow.

Problemas de aludes

    New and reactive wind slabs are building on non-typical areas with north outflow winds.

  • Persistent Slabs

    The early December weak layer may still be triggered in shallow, thin-to-thick areas, or with large loads like a cornice or avalanche.

Moderate

Avalanche Summary

No new avalanches were reported this week.

There have been no recent reports of persistent slab avalanches, but uncertainty remains. Snowpack test results and whumpfing suggest it may still be triggerable in areas that are shallow and rocky.

Snowpack Summary

Between 15 to 25 cm of old storm snow continues to be actively redistributed via moderate northerly winds. Watch for reverse loaded slopes hiding pockets of hard windslab.

A weak layer of facets and a crust from early December is buried 50 to 100 cm deep. This layer exists on all aspects up to around 1700 m.

At the highway elevation the snow is 120 cm deep and in the alpine there is more than 200 cm.

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
