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

Avoid areas where the wind has created deep deposits.

The new snow could be sitting on a touchy layer of surface hoar.

Moderate

Avalanche Summary

No new avalanches have been reported since the 25th of Nov.

Snowpack Summary

5 to 10 cm of new snow or wind loading may hide large surface hoar crystals in sheltered areas. This could be shallow, but easy to trigger.

Thin melt-freeze crusts may be found on sun-exposed slopes under the 5 cm of new snow.

The most prominent of several melt-freeze crusts in the lower snowpack is 100 - 150 cm deep in the Whistler area and decomposing.

Snowpack depth is around 130 cm at treeline and decreases rapidly below about 1500 m.

Weather Summary

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Avalanche Problems

Wind Slabs

Wind loading may hide buried surface hoar. This problem will be more likely in open areas, sheltered from the wind or where the wind is depositing snow.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
