Points saillants

Be cautious of areas where the surface snow feels heavy or dense.

Treat wind affected slopes with great caution, new and reactive wind slabs are likely.

    The recent snow was been transported by moderate to strong south westerly wind in to reactive wind slabs.

Confidence

Moderate

  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Avalanche Summary

Jan 7

  • Explosive control produced large avalanches (up to size 3) in the region

Jan 6

  • Natural and human triggered avalanches were reported in the region up to size 2.5 on a variety of aspects and elevations.

Jan 5

  • A few large (up to size 2) natural and human triggered storm slab avalanches were reported in the region, on east and north aspects at all elevations.

Snowpack Summary

The upper 40 to 60 cm of the snow pack is an accumulation of snow from the last few days. In places this could be resting on some feathery surface hoar crystals.

The snow has been affected by moderate southwesterly wind in open areas at treeline and in the alpine.

The prominent mid-December crust is buried up to 110 cm deep and extends to 2200 m. Triggering the crust is considered unlikely, except with large loads or in thin snowpack areas.

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Start on smaller terrain features and gather information before committing to bigger terrain.
