Regions

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

Watch for localized danger on sun-exposed and wind-loaded slopes.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Several natural and human-triggered storm slabs were reported Wednesday. They were size 1 to 2 and typically 20 to 30 cm thick.

Looking ahead, this storm snow snow will be most concerning on wind-loaded features (north and east aspects) and during times of sun-exposure (south and west aspects).

Snowpack Summary

Tuesday’s storm delivered 15 to 30 cm of new snow at upper elevations with strong south winds. This snow is expected to stabilize quickly, except on wind-loaded and sun-exposed slopes.

This snow fell on a mix of crusts and moist or isothermal snow, depending on aspect and elevation.

The lower snowpack has undergone multiple melt-freeze cycles, forming a mix of crusts and dense rounded snow.

Weather Summary

Wednesday Night

Partly cloudy. 1 to 2 cm of snow in the Duffey and Chilcotin. 30 km/h north ridgetop wind. Treeline temperature -8 °C.

Thursday

Mostly sunny. 20 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1500 m.

Friday

Mix of sun and clouds. 10 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1800 m.

Saturday

Mix of sun and clouds. 40 km/h south ridgetop wind. Treeline temperature +1 °C. Freezing level 2000 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Carefully evaluate steep lines for wind slabs.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.

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.
