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

Avoid exposed north and east slopes where wind and new snow have formed slabs that remain reactive to human triggering.

Moderate

Avalanche Summary

On Saturday, several avalanche control with explosives triggered several size 2 wind slab avalanches on northeast aspects at treeline.

We expect new snow will remain reactive to skier traffic on Monday anywhere winds have formed slabs and fast-moving dry loose avalanches in steep terrain.

Snowpack Summary

Storm snow totals range from 15 to 30 cm, with deeper deposits in wind-loaded areas.

The new snow is likely bonding poorly to old surfaces, which include melt-freeze crusts on sun-exposed slopes, surface hoar or facets on shaded slopes, and wind-affected snow at higher elevations.

The lower snowpack is strong and bonded.

Weather Summary

Sunday Night

Cloudy with light flurries, 1 to 5 cm of snow. 15 to 20 km/h northeast ridgetop wind. Treeline temperature -25 °C.

Monday

Partly cloudy with a trace of new snow. 20 to 25 km/h northeast ridgetop wind. Treeline temperature -25 °C.

Tuesday

A mix of sun and cloud. 10 to 20 km/h northeast ridgetop wind. Treeline temperature -26 °C.

Wednesday

Clear. 10 km/h northwest ridgetop wind. Treeline temperature -20 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Be especially cautious as you transition into wind-affected terrain.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.

Avalanche Problems

Wind Slabs

Use extra caution in north and east facing terrain where winds have formed deeper deposits. Watch for signs of instability: whumphing, shooting cracks and recent avalanches.

Aspects: North, North East, East, South East, South, North West.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2

Loose Dry

The new snow has bonded poorly to underlying layers. Watch for dry loose avalanche activity in steep terrain and manage sluffing carefully.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5
