Avalanche Summary

We have not had any reports of avalanche activity.

Please consider sharing any observations you have on the Mountain Information Network.

Snowpack Summary

Up to 5 cm of new snow from Tuesday night may have given a thin cover to a new layer of surface hoar. This grain hasn't been reported in the Cascades yet but has been growing vigourously in adjacent regions.

Below the surface, 10 - 15 cm of soft snow may still exist on sheltered, shaded slopes. In most other areas, especially the alpine, this snow has been heavily wind-affected. Cold temperatures are now faceting this upper layer, causing snow grains to lose cohesion.

Various melt-freeze crusts exist in the bottom half of the snowpack but do not appear to be avalanche concerns.

Around 100 cm of snow can be found at treeline. This diminishes rapidly below about 1500 m, where a surface crust is present.

Weather Summary

Thursday Night

Partly cloudy. 20 to 30 km/h west ridgetop wind. Treeline temperature -7 °C.

Friday

Cloudy with 2 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature -4 °C.

Saturday

Cloudy with 5 to 10 cm of snow. 30 to 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1100 m.

Sunday

Mostly cloudy with 1 to 2 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2500 m.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Carefully evaluate steep lines for wind slabs.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Avalanche Problems

Wind Slabs

Small new slabs could form with wind acting on slopes with soft, transportable snow.

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

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1 - 1.5
