In sintesi

A poor overnight refreeze and light rain will continue to break down the robust surface crust.

Avoid exposure to overhead hazards where the surface is soft, wet snow.

    A poor overnight freeze and light rain will break down the robust surface crust.

    Avoid exposure to overhead hazards where the surface crust is fully broken down into soft wet snow.

Confidence

Moderate

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

Avalanche Summary

Two human triggered wind slabs were reported on Thursday, just east of the region. These were both on northerly facing alpine slopes above 2500 m.

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. With a poor overnight freeze below 2500 m expected Friday night, and light rain forecasted for Saturday, the crust is expected to be less supportive over the weekend.

Up to 10 cm of dry snow overlies a crust in northerly alpine terrain.

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.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Avalanche danger will increase as the surface crust breaks down.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
