Weather Forecast

Monday's forecast shows mainly cloudy with light flurries and freezing level around 1600m. Alpine temperature around -6c and 30km/h wind.

Avalanche Summary

Numerous loose dry avalanches up to size 1.5 observed in past 48hrs on the Nov 12 crust mostly on E aspects in the Alpine.

Snowpack Summary

20cm of low density snow is overlying Nov 12th temperature crust. Isolated wind slabs observed in the Alpine along ridge lines and cross loaded gullies. There is an average of 50-60cm at 2200m and tapers quickly with elevation.

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.
