Avalanche Problems

Wind Slabs

Field observations show wind slabs still exist at higher elevations. Areas of most concern are above 2800m on the lee side of alpine ridges.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 3

Cornices

Strong winds from earlier in the month have created large cornices on lee (mostly easterly) aspects. Several large cornice collapses have been observed over the past week. These cornices could be a big enough to trigger a deep slab.

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

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 2 - 3
