Regions

South Coast, North Shore, Sky Pilot, Tetrahedron.

New snow has created heightened avalanche conditions at upper elevations.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported.

Weather patterns suggest small wind slabs could exist on some isolated leeward terrain features.

Snowpack Summary

Recent snowfall has ranged from 10 to 40 cm, with reports indicating rapid bonding. There may be unstable wind slabs on some steep alpine slopes.

The recent snow sits atop a widespread crust layer and a dense and well-bonded snowpack.

Weather Summary

Wednesday Night

Periods of snow with 20 to 30 cm of snow. 40 km/h southeast ridgetop wind. Treeline temperature -4 °C.

Thursday

Cloudy with scattered flurries and 5 to 10 cm of snow. 40 km/h southeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1200 m.

Friday

A mix of sun and cloud with isolated flurries. 10 km/h southeast ridgetop wind. Treeline temperature 0 °C. Freezing level 1500 m.

Saturday

Mostly sunny. 15 km/h northwest ridgetop wind. Treeline temperature +1 °C. Freezing level 1600 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Investigate the bond of the recent snow before committing to your line.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
