Regions

Glacier.

An incoming storm will bring bring new snow and wind to the alpine. Expect to find a storm slab building (especially in lee features!) over the next couple of days.

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

We are transitioning to a spring snowpack. Surface conditions vary from crust 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.

Weather Summary

A low pressure system will move through the region bringing snow and increased winds.

Tonight Cloudy with flurries, snow: 5cm. Alpine low -6°C. Wind SW-20 Km/h gusting 45. Freezing level(FZL) 1400m

Tues Snow, 14cm. High -4°C. Wind SW-15 gusting 45km/h. FZL 1500m

Wed Wet flurries, Snow 6cms. Alp High -6°C. Wind mostly light gusting 35km/h. FZL 1400m

Thurs Sun, cloud & flurries. Precip: 1-2mm. Wind 20km/h. FZL 1500m

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
