    Storm slabs are beginning to bond. Wind slabs have formed on north aspect terrain near ridge crests. Expect the likelihood of avalanches to increase with exposure to sun.

Avalanche Summary

On Monday a small (size 1) slab avalanche was skier-controlled on an east aspect at treeline. On Sunday a snowmobiler triggered a large (size 2) slab avalanche near Mt. Tod. Check out the MIN report here. On Saturday 1 small (size 1) natural avalanche was reported near Vernon in steep unsupported terrain. On Friday many small to large (size 1 to 2) wind slab avalanches were triggered by explosive control work in the region.

Snowpack Summary

35 to 50 cm of snow overlies a supportive crust.

Two weak layers of surface hoar and/or faceted grains associated with a crust from late January and mid-February may be found 80 to 100 cm deep.

The mid and lower snowpack is well settled and strong.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.
  • Carefully evaluate steep lines for wind slabs.
  • Investigate the bond of the recent snow before committing to your line.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
