Avalanche Summary

No new avalanches were observed or reported.

Snowpack Summary

In alpine terrain watch for windslabs along ridgelines and in gullied terrain. In these areas the snow may also be deeper as its blown in with up to 80cm in some areas. In general, 40-60cm of snow can be found at treeline. In lots of places this snow is likely overlying ground. As a result, a slope may look appealing but really, its pretty shallow. Tread lightly and use lots of early season caution. The only/best skiing opportunities are in alpine terrain. Forecasters have only been on road patrols this year and one short field day so observations are limited. Any human triggerred avalanche that occurs will likely lead to a ride over a rough ground surface that will likely hurt. With lots of season left, dont go rushing out the door expecting a winter snowpack.

Weather Summary

6-10cm of snow is forecast overnight and an additional 5-10cm throughout the day on Saturday. Winds will be moderate out of the SW and temperatures will be cooling throughout the weekend. The new snow will help the skiing but still a ways to go in many areas.

Terrain and Travel Advice

  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.
  • Winter conditions may exist in gullies, alpine bowls, and around ridgelines.

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.
