Wind slabs may remain triggerable on all aspects from recent variable winds

Keep safe travel habits in mind at all danger levels

Confidence

Moderate

  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.
  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

No new avalanches have been reported, but observations are limited. We expect wind slabs to remain triggerable by riders. If you are heading into the backcountry, please consider sharing your observations or photos to the Mountain Information Network.

On Thursday a size 3 avalanche in extreme, unskiable terrain was reported but details are limited.

Snowpack Summary

Strong westerly winds have likely redistributed recent snow into deeper deposits on north and east facing slopes at higher elevations.

The prominent mid December crust is buried up to 110 cm deep and extends to 2200 m. Several weak layers persist in the lower snowpack, but concern is limited to higher-elevation terrain where the crust above is absent. Triggering is considered unlikely, except with large loads.

Weather Summary

Monday Night
Partly cloudy. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Tuesday
Mostly cloudy. 1 to 2 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Wednesday
Mostly cloudy. 1 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Thursday
Mostly cloudy. 1 to 4 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Wind slabs are most reactive during their formation.
  • Use ridges or ribs to avoid areas of wind-loaded snow.

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.
