Regions

Maligne.

New snow and winds will increase the hazard through Friday and into the weekend. It is still early season so keep your tips up!

Confidence

Moderate

Avalanche Summary

Small loose wet avalanches observed around 1900m on south west aspects. One small wind slab was also noted in a cross loaded feature at the same elevation and aspect.

Snowpack Summary

Extreme SW winds stripping all exposed terrain in the alpine and into tree line. Wind slabs in cross loaded terrain. Freezing level around 2100m. Surface hoar size 3-10mm is buried 2-5cm down with uncertain distribution. Height of snow ranges from 20 to 70cm.

Terrain and Travel Advice

  • Minimize exposure during periods of heavy loading from new snow and wind.

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.
