Lo esencial

The snowpack is generally weak, facetted, and lacks cohesion. Assess for surface instabilities that have the potential to step down to deeper weak layers.

    Much of the lower snowpack is made up of weak, unconsolidated facets and depth hoar crystals. Steer clear of large slopes with a cohesive slab on the surface, likely created by previous wind loading. Any small avalanche or sluff in steep terrain has the potential to step down to this deeper layer, resulting in a large avalanche.

Avalanche Summary

Moderate

Snowpack Summary

The snowpack is unusually shallow and has a layer deep in the snowpack made up of weak facets and depth hoar. At lower elevations and shallower areas, the snowpack remains mostly unconsolidated.

The height of snow is roughly 50 to 200 cm at treeline.

Weather Summary

Thursday night

Cloudy with light snow, up to 5 cm. Temperatures -10 to -20 C and mostly light SW winds in the alpine.

Friday

Cloudy with a trace of snow. Temperatures of -5 to -15 C, and moderate southwest winds in the alpine.

Saturday

Cloudy with snow, up to 10 cm. Temperatures 0 to -5 C and strong south winds in the alpine.

Sunday

Cloudy with light snow, up to 5cm. Temperatures 0 to -5 C and strong south winds in the alpine.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • If triggered, loose dry avalanches may step down to deeper layers resulting in large avalanches.
  • This avalanche problem is difficult to trigger but if so, consequences are serious.
