Cooler temperatures are expected to lower the danger.

Watch for small wind slabs building with new snow and wind.

Summary

Confidence

Moderate

Avalanche Summary

On Sunday, numerous small wet loose avalanches occurred during warm temperatures and sunshine. A few of them triggered wind slabs.

Snowpack Summary

Large surface hoar crystals have been reported growing in sheltered spots at treeline and below. A surface crust is likely to form on solar slopes as the temperatures cool off.

15 to 30 cm of settling snow sits on either old wind-affected layers or possibly surface hoar in sheltered spots. In exposed areas, soft snow has been redistributed into wind slabs.

100 to 200 cm deep in the snowpack are layers of crust, facets, and possibly surface hoar that were buried in December.

The lower snowpack is generally well-settled and unconcerning.

Terrain and Travel Advice

  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Be careful as you transition into wind-affected terrain.

Problems

Wind Slabs

An icon showing Wind Slabs

New snow is falling with wind. Expect to find small wind slabs in lee terrain features.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 1.5

Persistent Slabs

An icon showing Persistent Slabs

It is unlikely that a person will trigger this layer. However, if a large load drops on a slope, like a cornice or an avalanche, it's possible it could step down deep in the snowpack.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Unlikely

Expected Size

2 - 3

Valid until: Jan 28th, 2025 4:00PM
