In sintesi

Expect surface conditions to change with daytime warming.

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

Problemi valanghivi

    • Alta quota

    Avoid exposure to cornices during strong solar input.

    As the sun melts the surface crust, wet loose avalanches may be possible to trigger as you travel.

Confidence

Moderate

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

Avalanche Summary

No avalanches have been reported since Monday. Use caution around cornices, especially during periods of sunshine.

Wet loose avalanches may be reactive to human triggers on sun-exposed slopes.

Snowpack Summary

Surface conditions are variable, with 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 (2–10 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.

Late March crusts are buried 10–80 cm deep, elevation and aspect dependent. The mid and lower snowpack is well settled and strong.

We expect minimal refreeze at treeline and below.

Saturday

Mix of sun and clouds. 1 mm of rain at treeline. 10 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2600 m.

Sunday

Mostly cloudy. 2 to 10 mm of precipitation as snow or rain at treeline. 20 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2200 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.
