Avalanche Problems

Wind Slabs

Moderate to strong winds continue to redistribute snow creating wind slabs on lee aspects and cross loaded features.

Be careful with wind loaded pockets while approaching and climbing ice routes.If triggered the wind slabs may step down to deeper layers resulting in large avalanches.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Persistent Slabs

The weak layer of surface hoar and facets from December can still be found and may become susceptible to triggering with more snow loading.

Be cautious as you transition into wind affected terrain.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
