Regions

Spray - KLakes.

Windy on Tuesday with a bit of new snow coming. Probably not enough snow to reset the tracks or change the hazard level. Ice climbers beware of overhead hazard.

Confidence

Moderate

Avalanche Summary

Nothing observed or reported.

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

Strong winds near 100km/h on Tuesday morning will usher in light snowfalls with accummulations

Terrain and Travel Advice

  • Ice climbers should be equipped with avalanche safety gear.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.

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.
