Points saillants

Cold and clear conditions have led to the development of large surface hoar crystals that may provide the next weak layer in the snowpack if and when we get any significant precipitation.

    Light snowfall and moderate SW through into Sunday will lead to the development of wind slabs on sheltered aspects. Any significant accumulations that overly existing surface hoar crystals could produce touchy conditions in a few isolated areas.

    The interface between the strong mid-pack and weaker basal facets is most susceptible to human triggering from shallow rocky areas.

Weather Forecast

Some snow flurries and moderate South Westerly are forecast for the Columbia Icefields area overnight and into Sunday.

Snowpack Summary

Cold and clear conditions have led to the development of large surface hoar crystals that may provide the next weak layer in the snowpack if and when we get any significant precipitation and slab build up. The interface between the strong mid-pack and weaker basal facets is most susceptible to human triggering from shallow rocky areas.

Avalanche Summary

No avalanches reported today.

Confidence

Intensity of incoming weather systems is uncertain on Sunday
