Kernpunkte

< 5cm of new snow is expected tonight; this will have little effect on the danger rating. A 2nd pulse in the storm track may produce up to 20cm at higher elevation on Thurs with mod to strong wind. Watch for loading and fresh wind-slabs.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    Wind slabs up to 1m deep are triggerable by climbers and riders in avalanche terrain. One thing to observe is the hardness of the slab; the greater the hardness, the greater the propagation potential. In sum, this means large avalanches are possible.

  • 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, cross-loaded features.
