Regions

Spray - KLakes.

The few cms of new snow did little to change the current avalanche danger. Its still early and thin and pretty tracked up out there. Ice climbers think about whats overhead.

Confidence

Moderate

Avalanche Summary

Nothing new.

Snowpack Summary

There is an average of 40-50cm of snow from valley bottom near the Spray road all the way up to Burstall Pass. This snowpack is faceted and weak, so do not be surprised to bump into things just under the snow(rock sharks and trees). There are some wind slabs out there, mostly where you'd expect them: in lee features and in cross loaded gullies.

Highwood pass has more snow but has seen more wind and traffic! The few cms of snow did little to improve the skiing and or raise the avalanche danger.

What is important is that in both areas the Nov 16th surface hoar has now been buried and may be an issue further down the road.

Weather Summary

A few cms of snow fell on Thursday but not enough to change the current avalanche danger. We are under the influence of an arctic ridge at this time and cool temps will be around for a few days. Unfortunately, not much in the way of new snow is expected.

More details can be found in the Mountain Weather Forecast.

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.
