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.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2
    Additional snow on Sunday and rising freezing levels into the high alpine may produce avalanches from this layer.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2
    Warm temperatures and additional load from snow or perhaps rain at lower elevations will make avalanches go to ground.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–4
    Warm temperatures and large loads such as from cornice failures may produce avalanches that step down into the weak layers deep in the snowpack.
