Kernpunkte

Cautious travel advised with these moderate ratings.  Extensive wind slabs  are touchy in places and if triggered can step down and bring the entire snow pack with it. 

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze

    This last wind event was strong and widespread effecting most aspects from treeline and above.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit

    If this layers if triggered, there is a likelihood of entraining the entire snowpack with it causing a large avalanche.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    2–3
    The big concern is that if anything gets triggered within the snowpack, then the avalanche will step down to the weak basal facets and involve the entire winter's snowpack.

Weather Forecast

Wednesday is showing a mix of sun and cloud with alpine high temperatures of -20c and NE winds of 15km/hr.  Outlook until Friday is mix of sun and cloud with temperatures between -11c and -22c.

Avalanche Summary

No new avalanches observed.

Snowpack Summary

Widespread wind slabs on most aspects in alpine and open areas at tree line.  These wind slabs are sitting on a weak and faceted mid-pack and basal layer.  The snow pack at lower elevations is shallow and faceted throughout, thus not supporting the weight of a skier unless on previously established ski paths.
