Avalanche Summary

A small skier triggered slab avalanche was reported on Saturday (see this MIN report). Similar avalanches might be expected under the current conditions in wind-affected areas.

Snowpack Summary

Winds have shifted to the northwest quadrant, which will build wind slabs on southeast aspects. Warmer temperatures have densified the upper snow pack. There is around 30 cm recent new snow that sits on a thick rain crust. The snowpack below the crust consists of moist to wet snow and is well settled. Snowpack depths are in the range of 150-250 cm around the peaks of the North Shore mountains (1400 m), tapering quickly with elevation to almost nothing below 1000 m.

Terrain and Travel

  • Approach lee and cross-loaded slopes with caution.
  • Avoid areas where the snow feels stiff and/or slabby.

Avalanche Problems

Wind Slabs

Recent winds have shifted to the northwest, setting up wind slabs on mainly southeast aspects in exposed locations.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
