Kernpunkte

Little change in weather and snowpack this weekend.  Cornice failure is a concern although we have not seen evidence as of yet.  Stay well back from corniced ridge lines.

Lawinenprobleme

  • Wind Slabs

    Wahrscheinlichkeit
    Unlikely - Possible
    Größe

    Wind slabs can be found above tree line in exposed terrain. These slabs have been unreactive to skier traffic, however, it is still possible to trigger a slab in steep unsupported terrain.

    Loose snow avalanches are likely on steep thin slopes and in gulley features. 

Weather Forecast

The weather on Sunday will be cloudy with snow flurries throughout the day producing light accumulation (5-10 cm).  Winds will be moderate to strong from the West and temperatures will be seasonable.

Snowpack Summary

The snowpack is faceting and losing strength especially in shallow areas.  At tree line and above, the mid-pack is generally supportive where the snow depth is greater than a meter.  Wind slabs are present in lee features at upper elevations. Surface hoar is developing with the cool overnight temperatures and light valley bottom winds.

Avalanche Summary

Avalanche patrols were conducted on both the Maligne Road and the Icefields Parkway.  No new avalanches were observed.
