Regions

South Coast, North Shore, Tetrahedron.

Challenging traveling conditions exist at treeline and below.

Pockets of wind-affected snow may be found at uppermost elevations.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported. Recent wet snow and rain may have caused wet loose avalanches in steep terrain, but field observations are limited.

Snowpack Summary

Up to 15-25 cm of moist snow may be found at uppermost elevations. This recent snow is settling rapidly and bonding well to the warm and moist snow beneath. The snowpack below 1500 m has been soaked with rain or diminishing rapidly. Total snow depths at ski hills and remote stations are 50 to 70 cm, with closer to 100 cm possible at treeline. Many areas are below the threshold depth for avalanches.

Weather Summary

Sunday Night

Partly cloudy, no accumulation, alpine wind southwest 20 km/h, treeline temperature around 0 °C, freezing level at 1000 m.

Monday

Mix of sun and clouds, no precipitation, alpine wind south 20 to 30 km/h, treeline temperature around +2 °C, freezing level at 1200 m.

Tuesday

Cloudy with 5-10 cm (rain below 1400 m) beginning by midday, alpine wind southeast 30 to 50 km/h, treeline temperature around +3 °C, freezing level at 1400 m.

Wednesday

Cloudy with isolated flurries, trace accumulation, alpine wind southwest 20 km/h, treeline temperature around +4° C, freezing level at 1800 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Investigate the bond of the recent snow
  • Be carefull around freshly wind loaded features.
  • 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.
