Regions: Cariboos.

Carefully assess the wind slab hazard as you gain elevation. New wind slabs could form throughout the day.

Confidence

Moderate - The snowpack structure is generally well understood.

Weather Forecast

Sunday night: Flurries bringing trace amounts of new snow at higher elevations. Moderate to strong south winds. Freezing level falling to 1500 m.

Monday: Cloudy with around 5 cm of new snow expected at higher elevations with moderate south winds. Freezing level around 2000 m.

Tuesday: Mostly cloudy with 5 to 15 cm of new snow at higher elevations. Light southeast winds and freezing levels around 1800 m.

Wednesday: Mostly cloudy with around 5 cm of new snow expected at higher elevations. Moderate west wind and freezing level around 1700 m.

Avalanche Summary

Only wet loose avalanches have been reported over the past few days. We suspect that small pockets of wind slab could be found in the alpine. As the freezing level rises small wet loose avalanches are possible.

If you are out in the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

Dry snow and pockets of wind slab can still be found on high north facing terrain. The upper snowpack contains several crusts that extend up to mountain tops on solar aspects. Moist snow will likely be observed at lower elevations.

Cornices are very large and exposure to slopes beneath them should be minimized, especially if the weather is sunny, warm, or windy. The snowpack deteriorates rapidly at lower elevations.

Terrain and Travel

  • Minimize your exposure time below cornices.
  • Carefully evaluate steep lines for wind slabs.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Avalanche Problems

Cornices

Cornices may be weak and reactive to human triggers. Give them a wide berth when travelling on ridges. They are a significant hazard alone and may produce large slab avalanches as they fall onto the slope below. Cornice falls are more likely when the weather is sunny, warm, or windy.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1.5 - 2.5

Wind Slabs

New wind slabs could form in the alpine.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
