Snowpack Summary

Snowpack continues to settle due to Diurnal conditions. Scoured from previous winds. Old hard slabs exists in the alpine and open tree line. More confidence in the southern snowpack. Cornices remain an overhead hazard, Surprisingly little activity noted recently.

Avalanche Summary

Loose wet cycle on all elevations on solar aspects yesterday, to Size 2.5

Confidence

Avalanche Problems

Wind Slabs

Potential for old lingering wind slabs

Winds have calmed to the Light range. Katabatic winds (Glacier outflow) will produce localized wind slabs.

Potential to wake up with day time warming on solar aspects

  • If triggered the wind slabs may step down to deeper layers resulting in large avalanches.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1.5 - 2.5

Deep Persistent Slabs

Large triggers may wake up this layer IE: Cornices in combination with day time warming

  • Be aware of the potential for full depth avalanches due to weak layers at the base of the snowpack.
  • Avoid shallow snowpack areas where triggering is more likely.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3.5
