In sintesi

A surface crust will make for challenging travel conditions but generally safe avalanche conditions. In isolated areas at upper elevations, pockets of wind slab may exist from northerly outflow winds.

    At upper elevations where dry surface snow may exist, northerly outflow winds may have created thin wind slabs in isolated areas. Watch for wind-loaded pockets, especially just below ridgetops and in extreme and very steep terrain.

Avalanche Summary

No new avalanches have been reported in this region since Jan 21.

Please continue to post your reports and photos to the Mountain Information Network, the information is very helpful to forecasters.

Snowpack Summary

A surface crust varying from thick and supportive to thin and breakable can be found in most locations. Above 700 m, 50 cm of dense, settling snow sits over a hard crust with wet or moist snow below.

The mid and lower snowpack is well-settled and consolidated.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
  • Watch for areas of hard wind slab on alpine features.
