Avalanche Forecast

Issued: Jan 8th, 2024 4:00PM

The alpine rating is moderate, the treeline rating is low, and the below treeline rating is below threshold. Known problems include Wind Slabs.

Assess for wind slabs in exposed areas. Good riding should still exist on sheltered, lower elevation slopes!




Avalanche Summary

Upper elevations where snow has been deposited into wind slabs is the main concern.

On Saturday, a size 2 avalanche was triggered remotely on a southeast-facing slope on a steep, wind-loaded feature just above treeline. Skiers in this area also reported whumpfing. These may have failed on the buried surface hoar detailed in the Snowpack Summary. Several other size 1 and 2 wind slab avalanches were also reported on both north- and south-facing slopes in exposed areas.

Snowpack Summary

10 to 20 cm of soft snow overlies hard surfaces. This soft snow may be redistributed into wind slabs in exposed areas.

A layer of buried surface hoar that formed on Christmas Eve may exist and be buried about 50 cm deep.

The lower snowpack is generally strong.

Snowpack depths range from 80 to 200 cm across the region and vary locally from wind distribution.

Weather Summary

Monday Night

Increasing cloud with trace snow, southwest alpine wind 20 to 40 km/h, treeline temperature -15 °C.

Few clouds with no precipitation, north alpine winds 50 to 70 km/h, treeline temperature -20 °C.


Few clouds with no precipitation, north alpine winds 40 to 60 km/h, treeline temperature -30 °C.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.


Wind Slabs

An icon showing Wind Slabs

North winds today mean wind slabs could exist on a variety of aspects. Watch for steep, lee or cross-loaded areas, and convex rollovers.

A layer of buried surface hoar may exist continuing to make these slabs reactive to human triggering.

Aspects: All aspects.

Elevations: Alpine.
