The weather pattern is stable

Avalanche Problems

Persistent Slabs

The buried surface hoar layer remains a concern in areas that have not recently avalanched. Solar effect will weaken the bridging strength of the slab on exposed slopes.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 2 - 4

Wind Slabs

Last week's snow was distributed by mostly moderate to strong winds into windslabs and cornices on North through Southeast aspects. Recent avalanches have started from rock bluffs or cornice failures and have triggered deeper weak layers.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

Expect to see small avalanches on steep solar slopes at lower elevations by noon. Ice climbers should consider these small avalanches if climbing on south through west facing climbs.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 2
