Kernpunkte

The next system will bring variable conditions to the mountains, depending on the time of day and your altitude.

Adapt your plans to these changes, and if in doubt, opt for conservative terrain.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely
    Größe
    1.5–2.5

    Up to 15 cm of new snow could be added to the few centimetres already available for transport. This snow will be heavier and could create reactive wind slabs on Tuesday.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–1.5

    Above zero temperatures and rain could weaken the top of the snowpack. Pay particular attention to steep slopes.

Avalanche Summary

Several small loose dry avalanches reacting to skiers were observed in the alpine.

If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

At all elevations, a thin sun crust can be expected on the E, S and W aspects. In the alpine, 10 to 15 cm of new snow have been redistributed by moderate winds and lie on a variety of old, wind-sculpted surfaces. In areas sheltered from the wind and below treeline, around ten centimetres of fresh snow cover a thin, breakable crust, on top of 20 to 40 cm of low-density snow. The snowpack is well consolidated, but a fragile layer of facets persists at the base in places where it is thinner. The height of the snowpack varies between 120 and 220 cm.

Tuesday: Cloudy. 1-2 cm of snow, possibly turning to rain. Southwest winds from 40 to 60 km/h. -3C. Freezing level: 700m.

Wednesday: Alternating sun and cloud. Winds from 5 to 15 km/h from the north. -8C.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
