Avalanche Summary

On Thursday, a natural avalanche was reported in the King Louie slide path on Hudson Bay mountain. Check out this MIN for more details.

Snowpack Summary

Light snow and southerly winds continue to redistribute recent snowfall. This snow is accumulating on a layer of surface hoar buried 10 to 30 cm deep. This layer of surface hoar is present in the alpine and on aspects that are not exposed to sunlight.

Another layer of facets, surface hoar and/or a crust buried in mid-February is 40 to 80 cm below the snow surface and has been reactive in snowpack tests.

Deeper in the snowpack, a weak layer of facets and a crust from early December can be found. This layer appears to be dormant but is still worth keeping in mind in thin snowpack areas in the alpine.

Weather Summary

Saturday Night

Cloudy with 5 to 10 cm of snow. 30 to 40 km/h south ridgetop wind. Treeline temperature -5 °C.

Sunday

Cloudy with 1 to 4 cm of snow. 20 to 30 km/h south ridgetop wind. Treeline temperature 0°C.Freezing levels reach 1500 m.

Monday

Cloudy with flurries. 0-5cm of snow. 30 to 40 km/h southwest winds at ridgetop. Treeline temperature 0 °C. Freezing levels reach 1500 m.

Tuesday

Cloud with flurries 30 to 40 km/h southwest winds at ridgetop. Treeline temperature -1 °C. Freezing levels reach 1600 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid shallow snowpack areas, rocky outcrops, and steep terrain where triggering is most likely.
  • Be aware of the potential for large avalanches due to buried weak layers.

Avalanche Problems

Persistent Slabs

Facets and/or surface hoar buried 50 to 80 cm deep are most prominent on north-facing slopes. Avoid areas with a thin or variable (thin to thick) snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1.5 - 2.5

Wind Slabs

Wind slabs will be most reactive where they overly surface hoar.

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

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1 - 1.5
