Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2
    Strong winds are redistributing snow into slabs on sheltered aspects and cross loaded features in the alpine.

  • Loose Wet

    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2
    Overcast conditions are unlikely to lead to any overnight refreeze of the snow pack at lower elevations. As such, solar aspects BTL could be prone to loose snow slides whenever the sun makes an appearance.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité

    Taille
    2–3
    Natural and human triggering is unlikely but it is still a good practice to avoid steep, open, rocky slopes with a shallow snowpack.

Weather Forecast

Continuing mild with moderate to strong south westerly winds at upper elevations. Isolated flurries are forecast for the Icefields area.

Snowpack Summary

A supportive mid pack consisting of rounded and facetted layers is bridging the weak depth hoar/facet layers that make up the lower snowpack. Wind slabs are developing in sheltered alpine locations from moderate to strong SW winds.

Avalanche Summary

No new avalanches reported by our field team today.
