Kernpunkte

There is the potential for loose dry and wind slab avalanches to be triggered in steep terrain.

    Where localized winds have redistributed new snow, cohesive slabs are forming. Small wind slabs have been reactive to skier traffic in steep terrain on a variety of aspects.

    Be mindful of sluffing in steep terrain, especially above cliffs or terrain traps.

Avalanche Summary

On Wednesday, two human triggered, size 2, wind slab avalanches were reported on northerly aspects in the alpine. They occurred in steep wind-loaded terrain and released above the crust. See MIN's here and here for details and photos.

Snowpack Summary

Anywhere from 15 to 35 cm of dry snow sits atop a widespread, hard crust. In general, the crust is strong and thick enough to be supportive to travel on up to 2400 m where it tapers out.

In the mid and lower snowpack, various weak layers persist in areas, however, triggering any of these layers is unlikely where they are capped by the supportive crust above.

Weather Summary

Saturday Night

Cloudy, 20 to 40 km/h west alpine winds, treeline temperature -5 °C.

Sunday

Cloudy with 5 to 10 cm of snow, 10 to 30 km/h southwest alpine winds, treeline temperature - 5 °C.

Monday

Cloudy with 5 to 15cm of snow, 20 to 40 km/h west alpine winds, treeline temperature -3 °C.

Tuesday

Mix of sun and cloud, 10 to 30 km/h north alpine winds, treeline temperature -4 °C.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
