Avalanche Summary

Numerous avalanches up to size 2 (72hrs old) on solar aspects in the Alpine due to last week's warm temperatures.

Snowpack Summary

Very limited observations. Snowpack depth up to 60cm at 2200m. Suspect rain crust on most aspects except for high north aspects. Wind loading in gullies and lee features. Snowpack is below threshold below treeline.

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.
