Continue to assess steep lines for wind slab

Light snowfall and west wind may form small wind slabs by late afternoon

Confidence

High

Avalanche Summary

On Thursday explosives triggered one size 1 wind slab avalanche. No other avalanches were reported on Thursday or Wednesday.

A few small wind slab avalanches were triggered in alpine terrain on Tuesday.

Snowpack Summary

Up to 5 cm of new snow is expected to accumulate throughout Saturday, covering a variety of surfaces. In sheltered terrain, it will land on facets and surface hoar, while on exposed slopes it will overlie wind-affected snow and a sun crust.

A weak layer that was buried at the end of January is down 30 to 80 cm in the snowpack. Depending on where you are, it'll be a combo of different crystals. With crusts on sunny slopes, sugary facets in most places, and surface hoar in sheltered spots.

The mid and lower snowpack is strong and bonded.

Terrain and Travel Advice

Carefully evaluate steep lines for wind slabs.

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.
