Points saillants

Wet loose avalanches remain possible, even small ones can push you into undesirable obstacles or terrain traps.

Cornices are weak, limit you overhead hazard to them and give ridge crests a wide berth.

    Large cornices exist on most ridge crests and our nearest neighbours have reported recent cornice failures. Be aware of your overhead hazard and avoid exposure to these lurking giants.

    Wet loose avalanches will remain possible until things cool down and the surface refreezes over Monday night. Heavy wet snow on the move can easily push you off line or off balance, be aware of this while traveling above terrain traps.

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

Spring conditions exist throughout the park. 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 cooling trend begins on Monday night with lowering freezing levels (FZL) and some new snow arriving on Tuesday.

Tonight Cloudy no precip. Alpine low -1°C. Wind W-10 Km/h. (FZL) 1900m.

Mon Flurries up to 4cm. Alp High -1°C. Wind SW-20-40km/h. FZL 1900m.

Tues Snow, 13cm. High -5°C. Wind SW-15 gusting 55km/h. FZL 1300m.

Wed Isolated flurries. High -7°C. Wind W-25km/h. FZL 1100m.

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.
