Regions

Glacier.

Storm slabs may be reactive to human triggering, especially on steep solar aspects and wind-affected features.

Weather Forecast

Today, cloudy with sunny periods, an alpine high of -7*C, freezing levels rising to 1300m, light SW winds, and scattered flurries tonight. Friday will bring a mix of sun and cloud, with light/moderate W winds, alpine high of -7*C, and freezing levels rising again to 1300m. The weekend brings cloudy conditions before a big warm-up early next week.

Snowpack Summary

Roughly 50cm of snow has fallen at tree-line over the last week. Moderate winds and mild temp's have created a cohesive soft slab which sits on: a sun crust on solar aspects; hard wind slab in exposed areas; and surface facets in sheltered locations. Steep solar aspects (SE through to W) now have a crust from yesterday's sunshine.

Avalanche Summary

A human-triggered size 1.5 avalanche on Glacier Crest took 2 people for a short ride on a W aspect at 2100m. Numerous loose, dry natural avalanches from size 1 to 2.5 were observed yesterday in the alpine when the sun hit at full-force. SE through to W aspects all shed surface snow. Macdonald Gullies 3, 9, 10, and 11 had slabs to size 2-2.5.

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.

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.
