Avalanche Summary

On Friday, skiers remotely triggered a slab on a northeasterly lee ridge feature at treeline near Mt. Fisher. Evidence from last week's natural avalanche cycle continued to be reported throughout the region.

Expect increasing avalanche activity within the surface snow with the forecasted warm weather.

Snowpack Summary

A spring diurnal cycle occurred up to 2000 m. The surface is either moist or capped with a thin crust on all aspects and elevations except for high northerly slopes where up to 25 cm of settled snow overlies a thick and supportive crust from late March.

The snowpack is quickly disappearing below treeline.

Terrain and Travel Advice

  • Carefully manage your exposure to overhead hazards.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Avalanche Problems

Loose Wet

As surfaces become wet, loose wet avalanches will become more likely on steep slopes at all elevations.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 1.5

Cornices

As temperatures rise, large cornice falls are becoming a concern. Carefully manage your exposure to overhead hazards during the warmest part of the day.

Aspects: North, North East, East, North West.

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 2 - 3
