In sintesi

20-25 cm of new snow is forecast for the Lake Louise area starting Tuesday afternoon. This new snow in combination with moderate to strong winds will result in increased avalanche hazard at all elevations.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely - Very Likely
    Dimensione
    1–2
    At treeline 30-40 cm of settled storm snow sits overtop of the Jan 20 facet interface. In areas where the wind has created soft slabs this layer is reactive to skier triggering. Immediate lees of ridges above treeline are the areas of most concern.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco

    In most parts of the forecast area a settled midpack overrides a weak facetted base. Be aware of steep shallow snowpack areas where the likelihood of triggering these basal facets is highest.
