Regions

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

Carefully assess and verify conditions as you move through terrain

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

Confidence

Low

Avalanche Summary

Small, natural and skier triggered wet and dry loose avalanches continue to be reported in the region.

Snowpack Summary

The upper  snowpack is highly variable. A crust exists on or near the surface on all aspects below treeline and on all sun exposed slopes.  On north aspects, Up to 20 cm of snow has buried a melt-freeze crust from late March. Below these crusts, the upper snowpack is moist.

A weak layer of facets from late January can be found down around 1 meter.

Weather Summary

Precipitation amounts over the next 24hrs could be highly variable due to convection.

Monday Night

Increasing cloud with 0 to 5 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Tuesday

Mostly cloudy with 1 to 4 cm of snow. 15 to 30 km/h west ridgetop wind. Treeline temperature -2 °C.

Wednesday

Mostly cloudy with up to 5 cm of snow. 15 to 30 km/h southwest ridgetop wind.  Treeline temperature -2 °C.

Thursday

Mostly cloudy with up to 15 cm of snow. 15 to 35 km/h northeast ridgetop wind. Treeline temperature -9 °C.

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.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.
