Kernpunkte

Previous snow and extreme winds have formed touchy wind slabs at higher elevations. Mild temps this week with freezing levels to 2000m on Wed. and the chance of another brief, but intense storm may increase the avalanche hazard. SH

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    Wind slabs up to 1m deep are triggerable in avalanche terrain. In sporatic TL places West of the divide, this may be sitting on the Dec.10 surface hoar, and facets in most other places. Avalanches could be quite large due to stiff wind slabs.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    2–3
    The basal facets/depth hoar are becoming less reactive in field tests, but If a wind slab is initiated, it may have enough volume to step down to create larger avalanches. Other trigger points will be thin, crossloaded features.
