Watch for changing conditions as you gain elevation.

the best riding conditions will be found in wind sheltered terrain.

    Rider triggerable wind slabs may linger in exposed terrain near ridge crests. Where the surface hasn't been wind affected dry loose avalanches are possible.

Confidence

Moderate

Avalanche Summary

No significant slab avalanches were reported over the past couple days. Natural and skier triggered dry loose avalanches up to size 1.5 have been reported from steep terrain where the recent snow hasn’t bonded to the underlying crust.

Snowpack Summary

Wind affected snow may be found in exposed terrain at higher elevations. A new surface hoar layer can be found on the surface in sheltered terrain.

10 to 30 cm of recent snow from the past weekends storm overlies a crust to 2200 m. The extend of this crust is uncertain in the alpine in the Selkirks. Where this crust is not present a layer of surface hoar may be found.

The mid and lower snowpack is well-settled, dense, and generally strong. Treeline snow depths range from 100 to 150 cm.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Make observations and continually assess conditions as you travel.
