Kernpunkte

Expect surface conditions to change with daytime warming.

Avoid steep sun-exposed terrain in the heat of the day.

Lawinenprobleme

  • Cornices

    • Hochgebirge
    • Waldgrenze

    Avoid exposure to cornices during strong solar input.

  • Loose Wet

    1–1.5

    It may be possible to trigger wet loose avalanches on sun exposed slopes if the surface crust breaks down.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of warming will affect the snowpack.

Avalanche Summary

A few small (size 1) wet loose avalanches were reported on Wednesday that were triggered by skiers on sun-exposed slopes.

Snowpack Summary

There is a widespread melt-freeze crust on most aspects, supportive in the morning and softening through the day—especially on sun-exposed slopes and at lower elevations. Recent snow (2 to 10 cm, up to 20 cm in wind-loaded areas) overlies the crust, with isolated wind slabs in alpine lee terrain. High north-facing slopes hold pockets of dry snow.

The late March crusts are buried 20 to 80 cm deep, elevation and aspect dependent. The mid and lower snowpack is well settled and strong.

We expect minimal refreeze below 2000 m.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
