Problems

Wind Slabs

Strong winds have created windslabs in leeward areas that are becoming stiff enough for a human trigger.

Use caution in lee areas. Recent wind loading has created wind slabs.

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

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 2

Deep Persistent Slabs

This problem is found in most north facing (shaded) terrain up to 2800m, and will become more reactive as the storm deposits more load.

If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.Whumpfing is direct evidence of a buried instability.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Unlikely - Possible

Expected Size

1 - 2
