Regions

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

At higher elevations, the snowpack continues to slowly accumulate. Reactive slabs may persist on top of a firm, slippery crust in alpine terrain.

Confidence

Low

Avalanche Summary

No new avalanche activity has been reported since Monday. However, field observations remain very limited.

Please consider sharing your observations with the MIN.

Snowpack Summary

At higher elevations, 10 to 40 cm of dry snow has been redistributed by southerly winds, forming pockets of deeper wind-loaded snow.

A thick, supportive crust formed in early November is widespread across alpine and upper treeline terrain, at depths varying from 30 to 100+ cm, depending on location and wind effects. Reports suggest weak faceted grains are developing above and/or below this crust.

Generally, snowpack depths range from 50–150 cm at treeline and above, with a dramatic decrease in coverage at lower elevations.

Weather Summary

Thursday Night

Clearing skies. 0 to 1 cm of snow at treeline. 20 km/h northeast ridgetop wind. Treeline temperature -4 °C.

Friday

Mostly sunny. 10 km/h east ridgetop wind. Treeline temperature -3 °C.

Saturday

Mix of sun and cloud. 0 to 2 cm of snow at treeline. 10 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Sunday

Mix of sun and cloud. 10 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • If it's deep enough to ride, it's deep enough to slide (avalanche).
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Be cautious of buried obstacles, especially below treeline.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
