Avalanche Summary

No new avalanches have been reported but information is limited.

Please consider submitting your observations to the MIN if you head to the backcountry.

Snowpack Summary

5 to 20 cm of recent snow sits on a hard melt-freeze crust except for shady high alpine slopes, where it sits on faceted snow over a hard crust. Thicker deposits may exist in lee terrain features near mountain tops.

A layer of weak faceted grains above a hard crust that formed in early February is buried about 50 to 110 cm deep. This layer is currently dormant.

Weather Summary

Sunday Night

Partly cloudy. 35 to 45 km/h west ridgetop wind. Treeline temperature -6 °C.

Increasing clouds. 20 to 40 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1600 m.

Tuesday

Cloudy with 10 to 20 cm of snow or rain. 50 km/h south ridgetop wind. Treeline temperature 5 °C. Freezing level 2000 m.

Wednesday

Partly cloudy with 5 to 10 cm of snow or rain. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Make observations and assess conditions continually as you travel.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme 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.
