Regions

South Coast, North Shore, Tetrahedron.

Avalanches are possible on slopes with wet or wind-affected snow.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported. Recent snow, rain, and wind may have caused isolated wind slab and wet loose avalanches in steep terrain.

Snowpack Summary

Freezing levels should favour snow accumulation at treeline and above on Thursday, with anywhere from 10 to 40 cm possible. This snow should bond well to the warm and moist snow beneath. Total snow depths at ski hills and remote stations are 60 to 80 cm, with closer to 100 cm possible at treeline. Many areas are below the threshold depth for avalanches.

Weather Summary

Wednesday Night

Cloudy with 10 to 30 cm of snow above 1300 m (rain below), alpine wind south 60 to 90 km/h, treeline temperature near 0 °C, with freezing level dropping to 1500 m.

Thursday

Cloudy with 10 to 20 cm of snow above 1300 m (rain below), alpine wind southeast 30 to 50 km/h, treeline temperature around +2 °C, freezing level climbing to 1700 m in the afternoon.

Friday

Cloudy with sunny breaks and no precipitation, alpine wind southeast 40 to 60 km/h, treeline temperature around +5 °C with freezing level climbing to 2500 m.

Saturday

Mostly cloudy with 2 to 8 cm of snow above 1500 m, alpine wind south 40 km/h, treeline temperature around +2 °C .

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Be alert to conditions that change throughout the day.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
