Regions

Lizard-Flathead, South Rockies, Flathead, Lizard, Elkford East, Elkford West.

Recent new snow coupled with wind is developing thin wind slabs in alpine terrain.

Confidence

Moderate

Avalanche Summary

There is no new significant avalanche activity to report.

Snowpack Summary

5 - 10 cm of new snow has accumulated over a crust at most elevations.

The middle of the snowpack is generally well bonded.

Near the bottom of the snowpack, there are a series of crusts and facets that are more prominent in shallow areas.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.
