Avalanche Summary

2 large wind slab avalanches were reported on southwest aspects, in the alpine, from reverse-loading on Saturday.

Snowpack Summary

The region has received up to 20 cm of new snow since Thursday. Strong easterly winds have reverse-loaded exposed terrain. The new snow likely overlies a layer of facets and, in sheltered locations, surface hoar. These snow crystals don't bond well with new snow and may contribute to the avalanche problem persisting.

A widespread crust with facets and/or surface hoar, buried in mid-January, is approximately 50 to 90 cm below the surface.

The lower snowpack is generally well consolidated.

Terrain and Travel Advice

  • Avoid slopes that sound hollow or drum-like.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
