Avalanche Summary

A few small dry loose avalanches were reported on Saturday and Sunday from steep slopes.

Snowpack Summary

Alpine areas have likely been affected by the wind reducing riding quality. In sheltered areas the cold is keeping the surface soft.

30 to 50 cm overlies a weak layer from late January. In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may be faceted grains or surface hoar. This layer hasn't been producing avalanches, but may become a problem when more snow arrives.

The mid and lower snowpack has no layers of concern.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.
