The best and safest riding will be on slopes with soft snow and no slab properties.

Avalanche Summary

No new avalanches have been reported since Friday when two separate parties accidentally triggered wind slabs near Whistler, and whumpfing was described in this MIN report.

Snowpack Summary

Wind-affected snow and wind slabs formed by recent shifting wind can be found on various aspects at upper elevations. Steep sunny slopes may be moist or have a thin surface crust, shady slopes are growing surface hoar.

35 to 70 cm of old storm snow is slowly settling and has remained dry and powdery in many areas with cold temperatures. This snow is sitting on a weak layer that developed in late January: In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may rest on faceted grains or surface hoar.

The mid and lower snowpack is well-settled and bonded with no other layers of concern.

Terrain and Travel Advice

  • Avoid areas where the snow feels stiff and/or slabby.
  • Be aware of the potential for large avalanches due to a buried crust.
  • Avoid lee and cross-loaded slopes at alpine and treeline elevations.

Avalanche Problems

Wind Slabs

Wind slabs have formed on a variety of aspects at upper elevations.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Persistent Slabs

A persistent weak layer of crust, facets or surface hoar is buried 30 to 70 cm deep.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 1 - 2.5
