Kernpunkte

Recent snow will be reverse loaded.

Avoid areas where the wind is actively depositing snow.

    Wind loading has switched directions, meaning wind slabs are possible on all aspects in the alpine. At treeline strong easterly winds are building fresh slabs.

    A 50 to 100 cm deep weak layer from early December may be possible to trigger on steep, rocky or convex slopes.

Avalanche Summary

No avalanches have been reported since Tuesday.

During the last avalanche cycle, wind slabs were able to step down to weak layers from December.

Snowpack Summary

10 to 30 cm of new snow is now above previous highly variable surfaces. Strong winds from all directions continue forming pockets of wind slabs.

This snow has fallen on a crusts on south-facing slopes, and in places, surface hoar at lower elevations.

A weak layer of facets and crust from early December is buried approximately 50 to 100 cm deep. This layer likely contributed to avalanches last weekend but should be less reactive under current conditions, primarily posing a concern on steep rocky slopes.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
