High

Avalanche Summary

The widespread avalanches activity from earlier this week 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

Warm temperatures persist until the weekend with no significant precipitation expected.

Check-out the Mountain Weather Forecast for more information.

Terrain and Travel Advice

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

Avalanche Problems

Loose Wet

Warming temperatures will continue to produce wet loose avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Certain

Expected Size: 1 - 3

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.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 2 - 4

Wet Slabs

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

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 3
