Kernpunkte

The avalanche hazard is trending up this week as the new snowfall is likely to build new storm slabs and potentially overload existing weaknesses in the snowpack.

    These slabs are found in sheltered locations, predominantly in high alpine locations.

    Storm snow has evolved into a persistent slab mainly around treeline and sheltered alpine slopes. Widespread whumphing in open treeline areas. Propagation from whumphing is possible on steep unsupported slopes.

Weather Forecast

A forecast of snow, moderate south westerly winds and milder temperatures will lead to the accumulation of slab at alpine and treeline elevations. Rain is likely below treeline.

Snowpack Summary

Warm temps are reaching into the alpine and are promoting settlement of last week's storm snow. Isolated windslab can be found in exposed areas in the alpine. The main concern is the interface between the settled storm snow and several crusts near the bottom of the snowpack. This interface is producing widespread whumphing at treeline.

Avalanche Summary

No field patrols today.

Confidence

Intensity of incoming weather systems is uncertain on Tuesday
