Avalanche Summary

Forecasters noted a Loose dry avalanche cycle up to size 1.5 today. Almost all originating from steep E aspects in the alpine, and not running all that far.

Snowpack Summary

10-15cm of snow fell Monday night. This snow fell with very light winds. This is sitting on top of a variety of wind pressed surfaces and bare rock. Use caution as the ground may be closer then you think in some location!

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Be aware of the potential for large avalanches due to the presence of a persistent slab.
  • Watch for areas of hard wind slab on alpine features.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
