Seek areas sheltered from the wind for the best riding and lowest avalanche hazard.

Moderate

Avalanche Summary

We haven't received any recent reports of avalanches. If you're heading into the backcountry please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

Around 10 cm of recent snowfall has improved the riding quality. Previous strong and variable winds created hard wind slabs on all aspects in the alpine which are now buried with this new snow. These slabs may sit on a layer of weak facetted grains which has the potential to make them easier to trigger. Soft snow, and the best riding, is likely to be found in sheltered terrain at treeline. The overall midpack is generally settled and strong, with the average snowpack depth at treeline around 150 cm.

Weather Summary

Wednesday Night

Cloudy with no new snow expected, south alpine wind 10 to 15 km/h, treeline temperature low -13°C.

Thursday

Cloudy with trace amounts of new snow possible, southwest alpine wind 30 to 40 km/h, treeline temperature -5°C.

Friday

Cloudy with 6-10 cm of new snow, south alpine wind 40 to 60 km/h, treeline temperature -3°C.

Saturday

Cloudy with 2 cm of new snow expected, southwest alpine wind 50 to 60 km/h, treeline temperature 0°C and freezing levels rising to 1100 m.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Approach lee and cross-loaded slopes with caution.

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.
