Anticipate wind slab formation at upper elevations with increasing winds and light snow forecast for Friday afternoon.

Confidence

Moderate

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Approximately 20 to 40 cm of recent snow exists at higher elevations. This snow has buried a thin rain crust.

The mid and lower snowpack is well consolidated with no current concerns.

Snow depth varies from 130 to 250 cm at treeline, while snow coverage decreases quickly at lower elevations.

Weather Summary

Thursday Night

Partly cloudy with 0 to 2 cm of snow. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -3 °C.

Friday

Cloudy with 5 to 10 cm of snow. 20 to 30 km/h east ridgetop wind. Treeline temperature -1 °C.

Saturday

Cloudy with 10 to 20 cm of snow at upper elevations. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Sunday

Terrain and Travel Advice

  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
  • Make observations and continually assess conditions as you travel.
  • Avoid areas where the snow feels stiff and/or slabby.

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.
