Snowpack Summary

In sheltered areas, above 2500 m there is 30-40 cm of recent snow that has been moved by extreme winds from the NE and W last week. Below 2400 m, the Nov 5 rain crust has 0-20cm of snow on top of a 3cm supportive crust. At tree line the snowpack ranges from 30-60cm deep.

Avalanche Summary

No new natural avalanche activity reported.

Confidence

Due to the number of field observations

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.
