Regions

Glacier.

The combination of a building storm slab on smooth open slopes, and very rugged travel in forested terrain, will make it challenging to find safe good skiing in the coming days.

Confidence

Low

Avalanche Summary

If there's enough to ride, there's enough to slide. Be sure to bring a transceiver, shovel and probe if you venture out.

If you do get out into the hills, consider posting a MIN report.

Snowpack Summary

Snow is starting to stick in the high-country. There is approximately 100cms of snow on the ground in the Alpine, 60-80cm at treeline, and 10-15 at highway elevation.

There is 6-12mm surface hoar on the surface in all open areas treeline and above. Expect this to provide a sliding layer for the incoming new snow.

Hidden rocks and logs lurk just below the snow surface in all terrain below treeline. Glaciers will have poor coverage with just enough snow to hide small crevasses.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
