Assess steep lines for wind slabs before committing.

Winter conditions still exist on high north facing terrain.




Avalanche Summary

Several small wet loose and skier triggered wind slab avalanches were reported yesterday.

If you have any recent photos or observations, please submit them to the Mountain Information Network, observations are limited in the spring

Snowpack Summary

Up to 5 cm of new snow may accumulate over a crust on all aspects at higher elevations. Small pockets of wind slab could be found on north and east aspects in the alpine. Below treeline rain will keep the snow surface wet or moist where snow still exists. Most below treeline terrain is already snow free.

Terrain and Travel Advice

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • Expect shallow snow cover that barely covers ground roughness.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
