Regions

Sasquatch, Coquihalla, Harrison-Fraser, Manning, Skagit.

Human-triggered avalanches remain possible after a week of snow accumulating over a crust and periods of strong wind.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

We do not have any recent reports of avalanches, but suspect recent avalanche activity has occurred in the alpine during periods of rapid loading from heavy snow and/or wind transport.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

Approximately 60 to 100 cm of snow has accumulated over the past week, burying a widespread crust at treeline and below. In alpine terrain, this crust is likely thin or absent. Periods of strong southwesterly wind have redistributed the new snow in exposed areas at higher elevations.

A crust with facets may exist 100 to 200 cm below the surface, primarily on northerly aspects at higher elevations. This layer appears unreactive but continues to be monitored.

The remaining snowpack appears strong and well-bonded.

Weather Summary

Saturday Night
Partly cloudy. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -9 °C.

Sunday
Mix of sun and clouds. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -8 °C.

Monday
Cloudy. 10 to 20 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1500 m.

Tuesday
Mostly cloudy. 15 to 45 mm of rain at treeline. 80 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2300 m.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Be careful as you transition into wind-affected terrain.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.
