Regions

Glacier.

Pockets of windslab may still be reactive to human triggering.

Use caution as you move into steep or convex terrain and practice good group management.

Confidence

High

  • Confidence is due to a stable weather pattern with little change expected.

Avalanche Summary

Natural avalanche activity has tapered off. However, this past week riders were able to trigger windslabs, especially in crossloaded terrain and near ridge top.

This is one example of a skier involved in an avalanche on Avalanche crest on Sunday (see MIN).

Snowpack Summary

Previous winds have created widespread wind effect in the Alpine and some open areas at treeline. 100cms of settled snow sits the Dec 15th crust, which exists below 2200m. The mid and lower snowpack are well settled and right side up.

Weather Summary

The high pressure will start to break down Friday with a return to stormier weather.

Tonight Clear periods. Snow: 0cm. Ridge wind SW-15km/hr. Freezing level FZL 600m

Thurs A mix of sun and cloud. Snow: 1-2. Alpine High -1 °C. Wind SW-10km/hr. FZL 1600m.

Fri Cloudy with flurries. Snow: 9cms. Alpine High -5. Wind SW-15 gusting 40 km/hr. FZL 1200m.

Sat Flurries. Snow: 13cms. Alpine High -1°C. Wind S 10-30 km/hr. FZL 1700m

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Avoid areas where the snow feels stiff and/or slabby.

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.
