Regions: Birkenhead, Brandywine, Duffey, Garibaldi, Homathko, Sea To Sky, South Chilcotin, South Coast Inland, Spearhead, Stein, Tantalus, Taseko.

Cornice falls may trigger large avalanches on slopes below.

Avoid traveling on slopes below cornices and give them a wide berth while traveling on ridetops.

Avalanche Summary

On Sunday, several natural and human triggered cornice failures up to size 2 were reported. See MIN

Snowpack Summary

High freezing levels have formed a surface crust everywhere except possibly the highest north facing terrain.

The snowpack is generally well-settled and strong, although dormant weak layers may still exist in shallow inland areas like the Duffey and Chilcotin.

Sustained high freezing levels with poor overnight recovery have the potential to awaken dormant weak layers.

Lower elevations are melting out rapidly.

Terrain and Travel Advice

  • Cornice failures could trigger large and destructive avalanches.
  • Avoid travelling on slopes below cornices.
  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Avalanche Problems

Cornices

Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1.5 - 2.5

Wind Slabs

Warm temperatures may increase the likelihood of triggering slabs, especially in steep, rocky, alpine terrain.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
