Regions

South Rockies, Akamina, Bull, Crowsnest North, Crowsnest South, Elkford East, Elkford West.

A cooling trend is making human-triggering of weak layers more difficult.

Use caution as you approach steep, rocky terrain, especially where there is no supportive crust.

Confidence

Moderate

Avalanche Summary

On Saturday, several small wet loose avalanches were reported with daytime warming.

Snowpack Summary

Recent snow has buried a widespread surface crust.

Depending on elevation, Refrozen and moist snow can be found in the upper snowpack, which overlies a settled mid-pack.

In the lower snowpack, a persistent weak layer of facets remains a concern for human-triggering.

Weather Summary

Tuesday

Partly cloudy, isolated flurries, 2 to 5 cm. 10 to 20 km/h west ridgetop wind. Treeline temperature -3 °C.

Wednesday

Partly cloudy, flurries, 5 to 10 cm. 15 to 20 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1700 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Make observations and continually assess conditions as you travel.

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.

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.
