Avalanche Summary

Avalanche activity on Sunday and Monday was reported as a few loose wet size 1-2 from steep alpine.

Snowpack Summary

There may be 10-30 cm of new snow sitting on the surface. This likely sits on a supportive crust or moist snow at all elevations except high north facing slopes. Weak faceted grains sitting a crust formed in early February are buried 100 to 150 cm. This layer has generally been gaining strength, however it is still occasionally producing large avalanches at upper elevations where supportive crusts have not formed above it.

Weather Summary

Monday Night

Cloudy with 5-15 cm snow at higher elevations. Ridgetop wind west and southwest 30 to 50 km/h . Treeline temperature -3 °C. Freezing level 1500 m.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Carefully evaluate steep lines for wind slabs.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs may be poorly bonded to the underlying crust.

Avalanche Problems

Storm Slabs

New snow and wind Monday night and through Tuesday will build fresh storm slabs. Deepest deposits can be found in lee terrain.
