Winds light from the west. THURSDAY: Continued light precipitation with light winds from the west. Freezing level at 100-1200m.

Avalanche Summary

No reports of recent significant avalanches in the region.

Snowpack Summary

Up to 50cm of recent storm snow from the past 3 days combined with moderate winds have formed windslabs in the alpine continued to build already very large cornices. There is moist snow on all aspects below 1600 metres.

Avalanche Problems

Cornices

Recent snow and wind have have made large cornices even bigger and more sensitive.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 3 - 7

Wind Slabs

Recent new snow and moderate southerly winds continue to build windslabs.

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

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 5

Deep Persistent Slabs

Persistent weaknesses are buried about 150-200 cm below the surface. Avalanche activity on this interface has become less frequent, but large triggers like cornice fall may release a large avalanche.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely

Expected Size: 3 - 7
