Lo esencial

New snow continues into the weekend, and winds are forecasted to increase.

Wind slabs will continue to form throughout the stormy days ahead. Use caution in wind loaded features as rider triggered wind slabs are likely.

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

Avalanche Summary

Earlier this week, several size 1 dry loose avalanches were observed in steep, sheltered alpine features. As well, a few wind slab avalanches to size 2 were observed in treeline and below treeline features.

Snowpack Summary

Up to 55cm of new snow is being redistributed into wind slabs in lee features. This sits over variable surfaces in the alpine and a new 3-8cm thick crust treeline and below treeline. Beneath this, 30–50 cm of settled snow overlies crusts and facets which is moist at lower below treeline elevations. The lower snowpack is generally well settled.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
