Points saillants

Rider-triggered sluffing is likely in steep, sheltered terrain.

New snow and wind may form reactive wind slabs at higher elevations.

Avalanche Summary

Numerous small (up to size 1.5) dry loose avalanches have been reported recently throughout the region, both natural and skier-triggered.

No recent slab avalanches have been reported.

Snowpack Summary

As much as 10 cm of new snow has accumulated in areas, with variable wind, potentially forming new wind slabs in exposed terrain. This new snow may overlie soft, faceted snow or surface hoar in sheltered terrain. A sun crust likely exists at or just below the surface on south-facing slopes.

20 to 50 cm overlies a variety of layers from late January. In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may be weak faceted grains or surface hoar.

The mid and lower snowpack is strong and bonded.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Wind slabs are isolated, but may remain reactive.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.
