Highlights

A persistent weak layer remains a concern, particularly in steep, sheltered areas at treeline.

Carefully evaluate steep terrain features before committing to them.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5

    Recent snow and wind built small wind slabs near ridgetops and on lee and crossloaded features at upper elevations. Wind slabs could step down to deeper weak layers.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2.5

    A persistent weak layer of surface hoar or facets over a crust is buried 30 to 60 cm. This layer has been most reactive around steep openings in the forest or high elevation cutblocks.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.
  • We are uncertain about how the timing or intensity of warming will affect the snowpack.

Avalanche Summary

No new avalanches were reported in the area.

Looking forward, natural avalanches are unlikely, but riders triggering slabs remains possible especially where there is no supportive crust.

Snowpack Summary

A few centimeters of new snow and strong winds may build small wind slabs at upper elevations. A supportive surface crust can be found on solar-facing slopes, and most areas at treeline and below.

A persistent weak layer of surface hoar or facets and a crust is buried 30 to 60 cm deep. Persistent slab avalanches are most likely in sheltered areas at treeline and below, where the surface hoar was well preserved.

The mid and lower snowpack are well settled in some areas. In others, large facets or depth hoar are present at the bottom of the snowpack.

Terrain and Travel Advice

  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Start on smaller terrain features and gather information before committing to bigger terrain.
  • Carefully evaluate steep lines for wind slabs.
