Very dangerous avalanche conditions exist at all elevations. Avoid all avalanche terrain.

Terrain and Travel Advice:
  • Avoid all avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Potential for wide propagation exists, fresh slabs may rest on surface hoar, facets and/or crust.
Persistent Slab

A weak layer of facets or surface hoar above a thick crust persists in the snowpack. If triggered storm slab avalanches may step down to this layer resulting in very large, destructive avalanches.

Storm Slab

As snow accumulates through the day watch for storm snow becoming a cohesive slab and increasingly reactive to triggers. Deeper deposits are expected in north and east facing terrain around ridgelines.

Avalanche Summary

On Monday, numerous skier remotely triggered persistent slab avalanches were reported up to size 2 in the region. These avalanches occurred mainly on north and easterly aspects between 1600 and 2000 m. A few remotely triggered windslab avalanches were also reported up to size 1 on north and south aspects at 1600 m.

Operators in the region also reported evidence of numerous natural, size 3, persistent slab avalanches that likely released during the previous storm.

Snowpack Summary

Storm snow accumulates over wind-affected surfaces and old wind slabs in exposed areas at all elevations.

Multiple weak layers exist in the upper and mid snowpack. The most concerning weak layer is found down 30 to 100 cm and is composed of a layer of facets or in isolated areas preserved surface hoar above a thick crust. This layer is the culprit of recent remotely-triggered avalanches in low-angle terrain. Professionals are concerned about how this layer will react to the new snow load.

Weather Summary

Tuesday Night

Cloudy with 10 to 20 cm of snow. 25 to 40 km/h southwest ridgetop wind. Treeline temperature -13 °C. Freezing levels remain at valley bottom.

Wednesday

Cloudy with 20 to 40 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature rises to -6 °C. Freezing level rises to 1200 m throughout the day.

Thursday

Mainly cloudy with 1 to 2 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature rises to -8 °C. Freezing level hovers around 800 m.

Friday

Mainly cloudy with 2 to 8 cm of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature rises to -8 °C. Freezing level hovers around 800 m.

More details can be found in the Mountain Weather Forecast.

Confidence: high
We are confident the likelihood of avalanche will increase with the arrival of the forecast weather.

Terrain and Travel Advice:
  • Avoid all avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Watch for fresh storm slabs building throughout the day.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • If triggered, storm slabs in-motion may step down to deeper layers and result in very large avalanches.
Persistent Slab

A problematic weak layer from early February, of facets overlying a crust, is becoming increasingly triggerable. This layer was the culprit of recent human-triggered avalanches in the region.

Storm Slab

As snow accumulates through the day watch for storm snow becoming a cohesive slab and increasingly reactive to triggers. Deeper deposits are expected in north and east facing terrain around ridgelines.

Avalanche Summary

On Monday, a size 2 skier accidental persistent slab was reported north of Pemberton. This avalanche occurred on a north aspect at 1800 m and failed on a weak layer of preserved surface hoar.

Several remotely triggered persistent avalanches were reported up to size two throughout the region. This is a clear sign the persistent weak layer is primed for human-triggering.

Evidence of a size 3, persistent slab avalanches was observed in the Duffey area.

Snowpack Summary

Storm snow accumulates over wind-affected surfaces and old wind slabs in exposed areas and settling snow in sheltered areas.

Multiple weak layers exist in the upper and mid snowpack. The most concerning weak layer is a widespread crust down 20 to 80 cm with a weak layer of facets or isolated surface hoar above this crust. This problematic layering is very concerning with recent large avalanche activity attributed to it.

Weather Summary

Tuesday Night

Partly cloudy with 2 to 8 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -10 °C. Freezing levels remain at valley bottom.
