Points saillants

Until cold temperatures lock in this warm and wet snowpack, dangerous avalanche conditions and poor riding quality will exist.

    Taille
    1.5–2.5

    Wet slab and wet loose avalanches are likely when the upper snowpack is saturated from rain and elevated freezing levels. They may be stepping down to buried weak layers in the mid and lower snowpack resulting in very large avalanches.

Confidence

Moderate

Avalanche Summary

Several wet loose and wet slabs up to size 2 have been reported in the region. These avalanches were reported from 2000 m.

Snowpack Summary

Wet snow exists in the upper snowpack to mountain top.

A layer of facets formed during the mid January cold snap sits 30-50 cm deep. Another weak layer consisting of a crust and facets is down 50 to 100 cm.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Keep in mind that wet avalanches can be destructive due to their high density.
