Points saillants

Limit your exposure to steep, sun-exposed slopes, especially if you are sinking into the snow beyond ankle depth. As the snowpack warms and weakens, you should increasingly opt for safer terrain.

Problèmes avalancheux

    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1.5–2.5

    The collapse of cornices can trigger larger wet loose snow avalanches. Cornices are found primarily on east to southwest slopes of Mount Albert.

    Taille
    1–1.5

    With warm temperatures and sunshine, small wet loose avalanches may occur, either naturally or triggered by skiers, on steep south-facing slopes. Watch for signs of instability: if, while travelling on foot, you sink into the snow up to your ankles, conditions are becoming favourable for wet loose avalanches.

    Pay particular attention near cliff bands and terrain traps, where even a small avalanche can have serious consequences.

Confidence

Moderate

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

Avalanche Summary

No new avalanches have been observed or reported.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

In alpine terrain and at treeline, the snowpack is gradually transitioning toward an isothermal state. Below treeline, this process is complete, and you can easily sink up to your waist when you remove your travel equipment.

The snowpack continues to melt below treeline.

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.
