Avalanche Problems

Deep Persistent Slabs

A 2m fracture line was observed today. Despite these observations being sporadic, they are still occurring and should remain on your radar and factor into your decisions. They are limited to alpine features above 2600m and running far.

Aspects: North, North East.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 4

Wind Slabs

The majority of the windslabs are bonding well, but there remains the potential to trigger them in isolated steep, wind loaded areas in the alpine.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3

Loose Wet

Large temperature swings from -20 at night to +2 during the day has us in a melt freeze cycle on south aspects. Freezing level is reaching 1500m or higher by midday. Steep south alpine slopes continue to release naturally in the afternoon.

Aspects: North.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2
