Kernpunkte

Tuesday should be a cooler day, but it is difficult to say how much the snowpack will re-freeze and stabilize. Keep a close eye on temperatures and solar radiation. Also, be mindful of touchy wind slabs at higher elevations. Ski quality is poor.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    Wind slabs are prevalent in Alpine and Treeline areas with a variety of slab thicknesses. Human triggering is a real possibility and caution is advised in lee and cross-loaded terrain.

  • Loose Wet

    Tuesday is expected to be much cooler, but solar triggered slides are still possible. Keep an eye on the temperatures and radiation and how this relates to the terrain around you. Ice climbers should avoid gully features on solar aspects.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze

    Unlikely - Possible
    Größe
    2–4
    Recent avalanches have stepped down to the December crust or the November weak basal layers.

Confidence

Fair - Freezing levels are uncertain

Weather Forecast

Tuesday will be a cooler day with Alpine temperatures near -3 celsius and freezing levels at 1800m. Winds will be strong out of the west and no precipitation is expected. Wednesday will see a further cooling trend and the winds will shift to the NW.

Avalanche Summary

Several solar and/or heat induced loose wet avalanches were observed today up to size 2.0. These occurred on all aspects except true North.

Snowpack Summary

The snowpack is settling as temperatures remained above freezing at Treeline elevations overnight. The snowpack is isothermal at lower elevations and in shallow snowpack regions, and is not supportive to travel. Wind slabs are prevalent in the Alpine and upper Treeline elevations due to previous extreme SW to W winds.
