    Where dry storm snow exists, strong wind may have formed wind slabs in lee areas.

Snowpack Summary

Up to 25 cm of snowfall overlies a crust from rain last week. Strong winds will have created heavily wind-affected surfaces and redistribute dry snow into wind slabs.

The remainder of the snowpack is strong, with various hard layers and crusts.

Confidence

Low

Avalanche Summary

A natural avalanche cycle occurred last week as rain impacted the region.

Looking forward, lingering pockets of wind slab at upper elevations will be the main concern.

Please consider submitting your observations to the Mountain Information Network.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
