Avalanche hazard is decreasing, however, recent winds made looking for good skiing a little more difficult.

Summary

Problems

Wind Slabs

An icon showing Wind Slabs

Recent avalanche control with minimal results, together with next to no natural activity proved this problem quite stubborn.

  • Watch for stiffer feeling snow. Avoid areas that appear wind loaded.

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

Elevations: Alpine.

Likelihood

Unlikely - Possible

Expected Size

1 - 2

Deep Persistent Slabs

An icon showing Deep Persistent Slabs

Triggering this layer would be a high consequence event - cautious decisions and thorough investigation is necessary. More likely to trigger this layer in transitions from thin snowpack to deeper loaded pockets or terrain features.

  • Use caution in thin snowpack areas.
  • Use caution on open slopes and convex rolls

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Unlikely - Possible

Expected Size

2 - 3
