In sintesi

Isolated small avalanches are still possible at low danger.

Remain cautious in extreme and high-consequence terrain.

Confidence

Moderate

Avalanche Summary

On Thursday, a small naturally triggered wind slab occurred near Panorama and a skier triggered a large (size 2) loose dry avalanche in the Esplanades.

Looking forward, we expect human triggering of wind slabs to be unlikely and loose dry avalanches possible.

Snowpack Summary

1 to 5 cm of recent snow may be covering a layer of surface hoar in sheltered areas, or a hard sun crust on sun-affected slopes. Up to 8 cm of additional snow may fall by the end of the day Sunday. Exposed terrain in the alpine and treeline is generally wind-affected. In sheltered terrain, 10 to 40 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun-exposed slopes and surface hoar on all other aspects. A weak layer of facets from early December is buried 60 to 120 cm. The base of the snowpack consists of a thick crust with facets or depth hoar in many areas.

Terrain and Travel Advice

  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Periods of low danger may be a good time to increase your exposure.
