Regions: Akamina, Crowsnest North, Crowsnest South, Elkford East.

Choose terrain sheltered from the wind for the lowest avalanche danger and the softest snow. Switching winds have developed wind slabs on all aspects.

Moderate

Avalanche Summary

No new avalanches were reported on Monday and Tuesday but observations were limited due to cold temperatures.

We expect that human triggered wind slab avalanches will be possible on Thursday.

Snowpack Summary

Storm snow totals range from 15 to 35 cm, with deeper deposits in wind-loaded areas. Wind has varied in direction, so expect to find wind slabs on all aspects.

The new snow may be 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

Wednesday Night

Partly cloudy with up to 2 cm of snow. 40 to 60 km/h west ridgetop wind. Treeline temperature -17 °C.

Thursday

Mainly sunny. 15 to 30 km/h west ridgetop wind. Treeline temperature -14 °C.

Friday

Partly cloudy. 20 to 30 km/h east ridgetop wind. Treeline temperature -15 °C.

Saturday

Partly cloudy. 30 to 50 km/h west ridgetop wind. Treeline temperature -15 °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.
  • Avoid freshly wind-loaded terrain features.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

Avalanche Problems

Wind Slabs

Variable alpine winds are developing wind slabs in isolated lee terrain features. Wind slab will be primed for human triggering. Minimize exposure during periods of heavy loading from wind.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
