Regions

Sugarbowl, Kakwa, McGregor, Pine Pass, Renshaw, Robson.

Warm temperatures are forming cohesive slabs over a widespread weak layer, which may be triggered by people.
During times of uncertainty, stick to conservative terrain.

Confidence

Moderate

  • We are uncertain due to how buried persistent weak layers will react with the forecast weather.
  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

Another day of above zero temperatures and sun. Natural and human-triggered avalanches may spike by the afternoon.

On Wednesday, several natural slab avalanches up to size 2.5 were reported.

Snowpack Summary

A thin melt-freeze crust likely exists as high as the alpine. With daytime warming and solar radiation the snow may become wet and heavy. Below this, a 30 to 60 cm cohesive slab sits above the late January surface, hoar/crust/ facet interface. The buried surface hoar is largest on sheltered treeline and below-treeline features.

Strong southwest winds may have formed deeper deposits of recent snow on northeast slopes in the alpine.

Check out this MIN from the Pine Pass for more details on the buried interface.

Sunday
Mix of sun and clouds. 5 to 10 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1200 m.

Terrain and Travel Advice

  • Avoid exposure to overhead hazards when solar radiation is strong.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Stay away from steep slopes, open slopes, and convex rolls at and below treeline where weak layers may be preserved.
  • Avoid travelling on slopes below cornices.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.

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.
