Highlights

Strong north winds and cooler temperatures will create poorly bonded windslabs on south facing features.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–3
    Strong north winds at higher elevations will continue to rearrange the windslab pattern from NE to more south facing slopes. Recent additional snow in the Icefields area will be moved to lee features.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–4
    Large avalanches could occur where smaller avalanches or cornice failures trigger a collapse in deep basal facets. A strong midpack is bridging this layer, except near wind exposed terrain.
