In sintesi

The warm, sunny conditions forecast for Sunday could quickly weaken the surface of the snowpack, increasing the danger of small wet-loose avalanches and making cornices more fragile. Limit your time on steep, sunny slopes, especially if the surface snow becomes wet.

Problemi valanghivi

  • Cornices

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

    The collapse of cornices can trigger larger wet loose snow avalanches. Cornices are found primarily on the southeast, south, and southwest slopes of Mount Albert.

  • Loose Wet

    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–1.5

    The warm, sunny weather forecast for Sunday will cause surface snow to melt, reducing its cohesion. Small wet-loose avalanches could then occur, either naturally or as a result of skiers passing by. Steep south-facing slopes will be most likely to be affected.

    Pay particular attention to areas of recent snow accumulation, near rocky escarpments and in terrain traps, where even a small avalanche can have serious consequences.

Avalanche Summary

No new avalanches have been observed or reported.

Confidence

Moderate

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

Snowpack Summary

In the alpine, a layer of 2 to 10 cm of relatively wet fresh snow lies on top of a hard crust formed by cycles of daytime thawing and night-time refreezing. Despite limited sunshine on Saturday, it is likely that south-facing slopes, as well as those at lower altitudes, were affected by the warmth and brief spells of sunshine. Alpine slopes are expected to refreeze overnight from Saturday to Sunday, before being influenced by the sun again on Sunday.

The snowpack continues to melt below the tree line.

At mid-mountain, the average snowpack depth is around 90 to 120 cm.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
