Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Strong wind and heavy precipitation is creating dangerous avalanche conditions.

Avoid avalanche terrain during periods of heavy loading from wind and snow.

Confidence

Moderate

  • Uncertainty is due to the track & intensity of the incoming weather system.

Avalanche Summary

On Saturday, skier-triggered wind slabs up to size 1.5 were observed at treeline, including a remotely triggered size 2 wind slab.

On Friday, there were a few large skier-triggered persistent slabs failing at treeline. It is suspected they both failed on surface hoar and/or sugary facets over a crust buried 30-50 cm deep.

Snowpack Summary

Up to 60 cm of storm snow overnight has buried wind affected snow.

This sits on a spotty layer of surface hoar on a crust that is 60 to .

The base of the snowpack has a few crusts from early in the season that are not currently a concern.

Weather Summary

Sunday Night
Cloudy. 60 cm of snow at treeline. 40 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1600 m.

Monday
Cloudy. 35 cm snow at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

Tuesday
Mostly cloudy. 2 to 10 mm of rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2500 m.

Wednesday
Mostly sunny. 1 mm of rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2400 m.

Terrain and Travel Advice

  • Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Be aware of the potential for large avalanches due to buried surface hoar.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
