Snowpack Summary

6-20mm Surface Hoar growing up to 2200m. 45cms of mostly undisturbed storm snow blanketing the region. This overlies a mosaic of buried wind slabs and facetted weak layers. Basal layers continue to develop into larger facets and depth hoar.

Avalanche Summary

No new avalanches observed or reported on Thursday, Growing cornices and small failures of cornices noted today.

Confidence

The weather pattern is stable

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
