Avalanche Summary

No new avalanches observed today, but there was evidence of an old cycle up to sz 2. These would have ran on the Nov crust mid storm.

Snowpack Summary

Valley Bottom: There is just enough snow to travel. Watch out for stumps and the typical willows. We are talking around 20cm of snow here.

Above 1950m: Last week's storm varies from 25-35cm of low density which is well bonded to the November rain crust. The crust starts to disappear at around 2350m so be careful in the higher elevations to not hit rocks or other features if the crust is not present. The height of snow is about 60-100cm on average.

There have been a few reports and observations of isolated wind slabs in the higher terrain so be alert to changing conditionsl.

Weather Summary

Monday will bring a mix of sun and cloud. The morning will start out around -13c in the alpine and warm up to -6c. Winds are forecast to be moderate NW in the morning and increasing during the day.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.

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.
