In sintesi

Low danger doesn't mean no danger, small wind slabs may remain triggerable at higher elevations.

    Small wind slabs may exist in steep, wind-loaded terrain features. Watch for convex slopes and cross-loaded features.

Avalanche Summary

Several size 1 slab avalanches were triggered by riders on Saturday, 10-30 cm deep, in the alpine and treeline.

If you go into the backcountry, consider submitting a MIN report.

Snowpack Summary

5 to 10 cm of new snow redistributed by recent winds overlies previously well-settled or wind-affected firm surfaces which may have a layer of weak, feathery crystals on top.

Below this, there is a thick and hard melt-freeze crust that extends into the alpine. The new snow buries this crust at lower elevations.

Weather Summary

Sunday Night

Partly cloudy. 30 to 50 km/h northwest ridgetop wind. Treeline temperature -10 °C.

Monday

Cloudy. 30 to 40 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Tuesday

Partly cloudy. 30 km/h north ridgetop wind. Treeline temperature -8 °C.

Wednesday

Few clouds. 20 to 30 km/h northeast ridgetop wind. Treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
