Avalanche Problems

Storm Slabs

Variable winds in alpine areas continue to form slabs on lee aspects. We've seen 70+cm of new snow since March 12th. Steep northerly terrain in the alpine is the biggest concern.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 3

Persistent Slabs

The Mid February buried surface hoar layer continues to produce dramatic sudden planar test results. This layer will be hard to trigger but if it does expect large destructive avalanches.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3

Loose Wet

As the spring season arrives even short periods of direct sun can have dramatic effect on the snow stability on solar aspects. Watch for increased loose snow avalanche activity during the heat of the day.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2
