Regions

North Columbia, North Rockies, McBride, Premier, Quesnel, Sugarbowl, Clemina, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

Recent snow and wind have created reactive wind slabs in lee features.

Back off slopes if the surface becomes moist or wet with rising temperatures and sun exposure.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
  • We are uncertain about how the timing or intensity of warming will affect the snowpack.

Avalanche Summary

A few very small rider-triggered wet loose avalanches were observed on Wednesday on steep sun-exposed slopes.

On Tuesday, small wind slabs were human-controlled near ridgecrests at treeline.

Snowpack Summary

Up to 20 cm of snow overlies a widespread crust from previous warm temperatures and sun up to 2100 m.

A hard crust is buried 30 to 70 cm deep, but may remain exposed in wind-scoured alpine terrain. It extends up to at least 1500 m in the Rockies, and 2000 m in the Cariboos.

Below the crust, the snowpack is strong and well-bonded.

Weather Summary

Saturday

Mix of sun and clouds. 2 mm of rain at treeline. 10 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2200 m.

Sunday

Mix of sun and clouds. 1 to 2 cm of snow. 10 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1400 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • 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.
