Kernpunkte

All melt no freeze... and natural avalanche activity is expected to continue.

    Warming temperatures will continue to produce wet loose avalanches.

    As the warmth continues to penetrate and soften the snowpack, wet slabs are more likely.

  • Deep Persistent Slabs

    The bottom of the snowpack is inherently weak with well-developed Facets and Depth Hoar. These avalanches have the potential to reach the end of run out zones well below tree line.

Confidence

High

Avalanche Summary

Widespread large loose wet and slab avalanche activity is occurring in the region. The main pulse of activity has subsided yet consider anything that has not slid to be highly suspect.

Post avalanche observations to the MIN.

Snowpack Summary

Many slopes at all elevations are isothermal and loosing cohesion particularly solar aspects and shallower snowpack zones. Depth hoar and basal facets at the base of the snowpack still exist until the warmth can penetrate fully.

Weather Summary

The next three days will remain sunny, very warm temperatures, no overnight freeze, and 3800 metres freezing level.

Terrain and Travel Advice

  • Only the most simple non-avalanche terrain free of overhead hazard is appropriate at this time.
