In sintesi

Watch for changing conditions with mild temperatures and sun.

Human triggered avalanches remain possible.

Problemi valanghivi

  • Wind Slabs

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

    Lee aspect features are likely to be reactive to human triggering.

  • Loose Wet

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

    Loose wet avalanches are most likely at upper elevations on steep south facing slopes.

Confidence

Moderate

  • Uncertainty is due to rapidly fluctuating freezing levels.
  • Uncertainty is due to how quickly the snowpack will recover and gain strength.

Avalanche Summary

On Thursday, several large (size 2-2.5) windslab avalanches where reported as being at least 72 hours old. The wind slabs where naturally triggered during the past storm with a few of them being triggered by cornice failures.

On Monday, a size 3 avalanche was observed, on a lee aspect feature that likely failed during the very warm temperatures. See picture below.

If you head out, please share any photos or observations to the Mountain Information Network.

Snowpack Summary

The snow surface is highly wind-affected in exposed alpine terrain. At treeline and below, the snow surfaces have formed a crust with moist snow below.

The upper and mid snowpack is saturated below 1600 m and with cooling has begun to reconsolidate, forming a surface crust up to 20 cm's thick. Expect this crust to impeded travel and pose additional slip and fall hazards.

A layer of facets is buried around 50 to 100 cm deep and is slowly gaining strength.

The mid and lower snowpack have no layers of concern. Snowpack depths are generally around 150-200 cm deep at treeline.

Terrain and Travel Advice

  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Make observations and continually assess conditions as you travel.
