Avalanche Summary

On Thursday several small storm and dry loose avalanches were reported in the region. The storm slabs were generally in wind-affected terrain.

Snowpack Summary

Up to 25 cm of new snow has fallen, this new snow will become moist on all aspects and elevation throughout the day on Friday, the exception will be high north facing terrain. Below this new snow is a crust from late March.

A weak layer of facets from late January can still be found down around 1 meter. This layer remains a concern on high north facing terrain where the late March layer isn't present.

The snowpack is quickly disappearing below treeline.

Weather Summary

Thursday Night

Mostly clear skies with trace amounts of snow possible. 20 to 40 km/h northwest ridgetop wind. Treeline temperature -14 °C.

Friday

Sunny. 20 to 30 km/h northwest ridgetop wind. Freezing level rising to 2100 m.

Saturday

Sunny. 30 to 50 km/h west ridgetop wind. Freezing level rising to 2500 m.

Sunday

Sunny. 20 to 40 km/h west ridgetop wind. Freezing level rising to 2700 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Avoid travelling on slopes below cornices.

Avalanche Problems

Storm Slabs

Storm and wind slabs will be most reactive on sun exposed slopes.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2

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

Wet loose avalanches are possible on sun exposed slopes and at lower elevations.

Dry loose avalanches are possible where new snow hasn’t formed a slab or become moist.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 1.5
