Regions

Sea To Sky, Brandywine, Garibaldi, Homathko, Spearhead.

Closely monitor local conditions throughout the day, as heightened avalanche conditions are expected with the arrival of new snow and increased winds.

Confidence

High

Avalanche Summary

A few small loose avalanches in very steep terrain have been reported since the weekend.

Otherwise, no new slab avalanches have been reported since a natural avalanche cycle late last week.

Snowpack Summary

Up to 50 cm of recent snow continues to settle and stabilize, with variable wind effects at higher elevations in exposed terrain.

While the mid and lower snowpack is generally well-settled, two crust/facet layers will be closely monitored as the snow load above continues to accumulate. These layers have a variable distribution and have not resulted in any recent avalanche activity.

Weather Summary

Wednesday Night

Cloud building overnight. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Thursday

Cloudy with 5 to 10 cm of snow. 20 to 30 km/h south ridgetop wind. Treeline temperature -5 °C.

Friday

Cloudy with 0 to 5 cm of snow. 20 to 30 km/h east ridgetop wind. Treeline temperature -3 °C.

Saturday

Cloudy with 5 to 10 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avalanche danger is expected to increase throughout the day.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Avoid areas where the snow feels stiff and/or slabby.

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.
