Kernpunkte

Human triggered avalanches are still a concern despite the lack of natural activity.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze

    Mostly 10cm thick slabs in open areas at all elevations.

  • Persistent Slabs

    This persistent slab is dense and is sitting on top of a 10cm weak facet layer.  If this layer fails, it has the potential to trigger the deeper November crust.

  • Deep Persistent Slabs

    • Waldgrenze

    Triggering is more likely in shallow snowpack areas and rocky features.

Weather Forecast

Sunny skies forecast for Tuesday with a high temperature of -20c and light winds form the Nortrh.

Avalanche Summary

One natural avalanche size 2 observed in steep unskiable terrain on an East aspect at 2600m.

Snowpack Summary

A wind slab on the surface up to 10cm is found mostly in open areas at all elevations. Our main concern in the snow pack is the persistent slab that sits on a 10cm facet layer(December 18th layer) approximately 35cm down. Our second concern is the November rain crust which is located in the lower third of the snowpack mostly below 2400m. Below tree line, the snowpack is mostly faceted and not very supportive to skier traffic.
