    Wind slabs may be possible to trigger at high elevations when new snow is being loaded into leeward terrain features.

Terrain and Travel Advice

  • Be alert to conditions that change with aspect and elevation.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.

Avalanche Summary

There have been no recent avalanche reports in the region.

If you are going out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Newly formed surface hoar may exist in wind-sheltered, open terrain. A thin melt-freeze crust may exist on south-facing slopes.

In the alpine, 20 to 40 cm of snow from last weekend sits above a thin crust. At lower elevations, 10-20 cm of snow sits above a more robust crust. The snow is moist below the crust.

Snow depths at treeline vary across the region. Around 90 cm is reported in the Coquihalla and 60 cm near Manning Park.
