Points saillants

A rising freezing level up to 3000 meters is expected for the South Rockies. Should this system enter the Jasper forecast area, watch for cornice failures in the alpine as well as loose wet avalanches below treeline.

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2
    Additional snow on Sunday and rising freezing levels into the high alpine may produce avalanches from this layer.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2
    Warm temperatures and additional load from snow or perhaps rain at lower elevations will make avalanches go to ground.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
