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

Carefully assess and verify conditions as you move through terrain

Use extra caution in shallow rocky terrain, especially on north facing alpine slopes

Confidence

Moderate

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 60 to 100 cm.

Weather Summary

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

Tuesday Night

Mix of cloud and clear skies with 0 to 5 cm of snow. 15 to 30 km/h west ridgetop wind. Treeline temperature -8 °C.

Wednesday

Mix of sun and cloud with up to 10 cm of snow in the afternoon. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Thursday

Mostly cloudy with up to 5 cm of snow. 20 to 40 km/h north ridgetop wind. Treeline temperature -8 °C.

Friday

Sunny. 10 to 30 km/h northwest ridgetop wind . Treeline temperature -5 °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.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Avoid travelling on slopes below cornices.
  • Make observations and continually assess conditions as you travel.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Avalanche Problems

Persistent Slabs

A weak layer from late January is a concern in shallow north facing terrain in the alpine. Be especially leary of slopes that match this description and have a cornice above.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3

Loose Wet

Pulses of new snow and fluctuating freezing levels will likely keep wet loose avalanches possible.

Dry loose avalanches are also possible where recent snow hasn't formed a slab or become moist .

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
