Regions

Glacier.

Recent snow is forming a cohesive slab, this will be most reactive where there is wind effect or during times of intense solar warming.

Cold temperatures are forecast. It'll be especially chilly in the shade or when the sun goes down. Pack an extra warm clothing layer!

Confidence

High

Avalanche Summary

There were two reported skier triggered avalanches yesterday. One on Terminal Pk and the other in the Connaught drainage. They were both slabs within the recent storm snow that ran approximately 150 meters

Isolated slab avalanches (Avalanche Mtn last week, Sapphire Col on Saturday) continue to surprise folks from shallow snowpack areas in the Alpine. Thin snowpack areas, which in normal years have over 3m of snow by now, need to be treated with more caution this year.

Weather Summary

A high pressure system will bring cold Arctic air into the region. Expect cold temps and clear skies.

Tonight: Clear with cloudy periods, nil precip, Alp low -16°C, E winds 20km/hr, freezing level (FZL) valley bottom.

Thurs: Sunny, Alp high -14°C, winds E: 25km/hr, FZL valley bottom.

Fri: Sunny w cloudy periods, Alp high -7, winds SE 10 km/hr, FZL 1000m

Terrain and Travel Advice

  • Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

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.
