Keep an eye on the wind. As it increases and snow starts to blow new wind slabs could form in exposed terrain.

Summary

Confidence

Moderate - Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Weather Forecast

Sunday night: Possibility of light flurries bringing trace amounts of new snow with light southwest winds. Low of -11 at 1100m.

Monday: A mix of sun and cloud with light flurries bringing trace amounts of new snow. Moderate southwest winds. High of -3 at 1100 m.

Wednesday: Cloudy with flurries bringing up to 5 cm of new snow with light to moderate southwest winds. High of -3 at 1100 m.

Avalanche Summary

On Friday ski cutting produced wind slab avalanches up to size 1.5. Several wet loose avalanches to size 1.5 were also observed, these avalanches were on steep low elevation features.

Snowpack Summary

New wind slabs could form in exposed terrain as the winds increase. Moist snow could be observed on solar aspects if the sun comes out.

A couple of sun crusts exist in the upper snowpack but none have been identified as layers of particular concern. The lower snowpack is thought to be well settled.

Terrain and Travel

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Minimize your exposure time below cornices.

Problems

Wind Slabs

Wind slabs could be found on north and east aspects in exposed treeline and alpine terrain.

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

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 2

Cornices

Cornices have grown large recently. Give them a wide berth when travelling on or below ridges. The likelihood of cornice falls can increase with solar input.

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

Elevations: Alpine.
