Pay close attention to solar radiation and avoid being below big terrain when this in full effect particularly in the afternoon.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    New snow and west winds could create wind slabs in the alpine. These slabs sit above a new surface hoar layer and temperature crusts on solar facing slopes.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely
    Tamaño
    1.5–2.5
    The weak and facetted snowpack is about to be tested by warming temperatures, then some new snow, for the first time in over a month. Triggering of the basal weakness may become possible in areas where the snowpack above still retains some cohesion.

Weather Forecast

The cold ridge of high pressure has finally broke down by a series of lows moving inland bringing warmer moister air and a little precip over the region. Friday: A mix of sun and cloud. Alpine High -8 C, Low -15 C. Snowfall up to 10cm across the range with light winds SW gusting Moderate.Mountain weather forecast available at Avalanche Canada.

Snowpack Summary

10cm of new snow through Friday and moderate winds could create new windslabs in the alpine. New snow will bury a new surface hoar layer, facets and crusts. The upper snowpack remains generally facetted. The mid and lower snowpack is facetted but still generally carries skis. Below treeline warmer daytime temps will weaken the snowpack.

Avalanche Summary

No new avalanches have been observed or reported.

Confidence

Intensity of incoming weather systems is uncertain
