Avalanche Summary

Recent reports have been limited.

If you do go into the backcountry, please consider submitting a MIN report.

Snowpack Summary

10 to 20 cm of recent storm snow has been redistributed into wind slabs in the alpine. A new crust will likely be found at treeline on all aspects.

The mid pack contains several other crusts.

elow treeline, most areas are below the threshold for forming avalanches.

Weather Summary

Monday Night

Clear with no new snow expected, west alpine wind 10 to 15 km/h, temperature inversion with an above freezing layer at 1500 m.

Tuesday

Clear skies  with no new snow expected, north alpine wind 5 to 15 km/h, treeline temperature -1°C.

Wednesday

Clear skies with no new snow expected, east alpine wind 20 to 40 km/h, treeline temperature -5°C.

Thursday

Increasing cloud with trace amounts of new snow expected, east alpine wind 20 to 40 km/h, treeline temperature -4°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Travelling on skis is hazardous due to a very shallow mountain snowpack.

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.
