Regions

Sea To Sky, Brandywine, Garibaldi, Homathko, Powell River, Spearhead, Tantalus.

Rising freezing levels and clear skies are creating heightened avalanche danger on steep slopes.

Approach steep slopes with caution and back off if the surface becomes moist.

Confidence

Moderate

  • Uncertainty is due to rapidly fluctuating freezing levels.

Avalanche Summary

No new avalanches were reported. As freezing levels rise human triggered slab avalanches are possible.

Reports of a surface hoar layer in the area at treeline could see small human triggered slab avalanches continue in sheltered terrain features.

Snowpack Summary

Surface snow is variable, on steep solar facing slopes moist snow is present and on north facing slopes above 2000 m the snow remains dry and wind affected.

Within the upper snowpack a surface hoar layer can be found roughly 30 cm deep in sheltered treeline terrain.

A crust buried on December 16th is roughly 150 cm deep. Above 2200 m, this crust is absent and an old crust complex and faceted snow from November is found at the base of the snowpack.

Weather Summary

Wednesday
Mix of sun and clouds. 2 to 5 mm of precipitation as snow or rain at treeline. 20 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1900 m.

Thursday
Mix of sun and clouds. Isolated flurries 1 to 2 cm. 20 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Be especially cautious as you transition into wind-affected terrain.
  • Wind slabs are isolated, but may remain reactive.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.

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.
