Lawinenprobleme

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1.5–3

    Cornices can be extremely destructive alone or, may initiate deeper layers in the snowpack below.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–3

    More activity noted at this layer, mostly initiated by large loads (cornices) in steep terrain.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–2.5

    Varied sensitivity on solar aspects, likelihood increases on the steepest slopes. It ay nbe possible to trigger deeper instabilities once initiated.

Weather Forecast

Approaching front will bring high light clouds which should filter the UV and keep the surface snow cool. Cold overnight recoveries help to maintain the structure of the snowpack. Isolated sun and clouds will mean localized areas of instability. 

Snowpack Summary

Warm temps and high solar input has created typical spring like conditions with moist snow on solar aspects from daytime heating, TL and below. Continuing SW winds have redistributed the snow pack, forming hard slabs in the ALP. The mid pack is supportive in deep areas, but shallow snowpack areas are weak and will break down fast with temp swings.

Avalanche Summary

Control operations produced several loose wet slabs on previously controlled terrain.
