In sintesi

Avoid wind loaded areas and only expose one person at a time to avalanche terrain.

Conditions can change rapidly in spring, read about the 4 likely scenarios here.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2

    Riders may trigger slabs in wind loaded areas. Strong wind may form new wind slabs.

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1.5–2.5

    Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

Confidence

High

Avalanche Summary

A small wind slab was seen on Monday from a northwest facing slope at treeline.

Avalanche activity has tapered since the weekend, and so have the number of observations.

Snowpack Summary

Around 10 cm of recent snow redistributed by southerly wind lies over a crust that goes up to 1250 m in the shade and up to mountain top on slopes that get the sun. Good riding can still be found in sheltered slopes away from the sun.

The mid-pack is generally well settled, with crusts buried around 50 cm, and another near 130 cm deep.

The lower snowpack is facetted, but hasn't been a problem.

Below 1100 m the snowpack is wet and losing strength.

Cloudy. 40 to 80 km/h south ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid freshly wind-loaded terrain features.
