Avalanche Summary

On Wednesday, there was a large cornice failure that triggered a wet loose avalanche out of extreme terrain.

Observations are limited at this time of year.

Snowpack Summary

A thin cust is likely to have formed over up to 20 cm of recent snow at upper elevations. This snow overlies a robust crust everywhere except northerly aspects in the alpine.

Most terrain has undergone strong melt-freeze cycles, creating a strong, well bonded snowpack.

Terrain and Travel Advice

  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avalanche danger will increase as the surface crust breaks down.

Avalanche Problems

Loose Wet

Wet loose avalanches will become more likely as the sun and warmth affect the snowpack. Start early, and avoid the hottest part of the day.

Aspects: East, South East, South, South West, West.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5

Cornices

Cornices are more likely to fail during warm weather.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1.5 - 2.5
