Regions

Glacier.

As storm has brought new snow and wind to the alpine. Expect to find a reactive storm slab, especially in lee features.

Confidence

Moderate

  • We are uncertain due to the track and intensity of the incoming weather system.

Avalanche Summary

Several wet loose avalanches up to size 2.5 and a size 3 glide slab release have been observed through the highway corridor over the weekend. Neighboring operations have reported natural cornice failures.

Snowpack Summary

10-20cms of new snow sits on top of a variety of old spring-like surfaces. Anything from crusts to moist or wet snow depending on time of day, aspect and elevation.

A thick rain crust from the March atmospheric river sits 20-50cm below the surface.

Below treeline the surface varies from isothermal sticky snow to refrozen tree bombs and huge debris fields from the massive avalanche cycle in March.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Avoid travelling on slopes below cornices.
  • Watch for fresh storm slabs building throughout the day.

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.
