Regions: Coquihalla, Harrison-Fraser, Manning, Sasquatch, Skagit, Stave.

Heightened avalanche conditions exist on wind loaded features in the alpine. Avoid freshly loaded terrain features, especially around ridge crests, roll-overs and steep terrain.

Confidence

High

Avalanche Summary

No recent avalanches have been reported in the region.

If you do head into the backcountry please consider submitting observations and/or photos on the Mountain Information Network.

Snowpack Summary

5 to 10 cm of storm snow overlies a weak layer of surface hoar above a breakable crust that extends well into the alpine. The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.

Overall, the snow depth remains relatively shallow, creating challenging travel conditions and numerous hazards at or just below the snow surface across all elevations.

Weather Summary

Thursday Night

Partly cloudy with no precipitation, southwest alpine winds 20 to 30 km/h, treeline temperature 0 °C, freezing level rise to 2000 m through the night.

Friday

Mostly sunny with no precipitation, southwest alpine winds 30 to 50 km/h, treeline temperature +1 °C, freezing level 2200 m.

Saturday

Mostly sunny with no precipitation, west alpine winds 50 to 60 km/h, treeline temperature +2 °C, freezing level 2500 m.

Sunday

Mostly sunny with no precipitation, west alpine winds 30 to 40 km/h, treeline temperature +5 °C, freezing level 3000 m.

Terrain and Travel Advice

  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

Avalanche Problems

Wind Slabs

Watch for southwest winds picking up throughout the day and redistributing recent storm snow into alpine lees. Use caution when transitioning into wind affected terrain, wind slabs are most reactive during their formation.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
