As the temperatures drop, so too should the avalanche danger.

Continue to assess your local conditions, if they don't match the forecast change your plan to something safer.

Confidence

High

Avalanche Summary

On Sunday night a large avalanche was likely triggered by a cornice falling into extreme terrain on Atwell Peak. Check out the MIN report here.

Snowpack Summary

A crust has likely formed on the surface at treeline and below, and on steep slopes in the alpine that saw the sun. Surface hoar has been growing in terrain sheltered from the wind.

An otherwise right-side-up upper snowpack appears to be bonding well to a crust buried 70 to 100 cm deep. The mid and lower snowpack is generally well-settled and bonded with no layers of concern.

Weather Summary

Tuesday Night

Cloudy with 1 to 3 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Wednesday

Cloudy. 10 to 20 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1400 m.

Thursday

A mix of sun and cloud. 20 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 2500 m.

Friday

Cloudy. 30 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1100 m.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • The snowpack is generally stable; it may be appropriate to step out into more complex terrain.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
