Avalanche Problems

Wind Slabs

The first bit of wind after the storm on Dec 21, fresh wind slabs were noted building today

  • Use caution in lee areas. Recent wind loading have created wind slabs.
  • Be careful with wind loaded pockets while approaching and climbing ice routes.

Aspects: North, North East.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5

Loose Dry

New snow has stuck to and accumulated on all features, caution in terrain traps while approaching climbing routes.

  • If triggered dry loose point releases can form deeper deposits in terrain traps.
  • Use caution above ledges and cliffs where small avalanches may have severe consequences.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
