Regions

Coquihalla, Harrison-Fraser, Manning, Skagit.

New snow is being redistributed by moderate winds, developing wind slabs at upper elevations.

Watch out for signs of instability, and assess steep, lee terrain features before committing.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
  • We are uncertain due to rapidly changing freezing levels.

Avalanche Summary

Several wet loose avalanches were reported over the weekend, involving the most recent storm snow over the robust crust.

Upper elevations may be holding some dry snow that may be redistributed by moderate southwest wind building wind slabs in lee features.

Snowpack Summary

Roughly 15 to 20 cm of heavy snow has buried wind affected surfaces at upper elevations. At treeline and below the upper snowpack is saturated.

Below this, a variable (robust to breakable) crust sits over a facet layer at treeline and above. In sheltered features a surface hoar layer may have survived the recent warm temperatures and rain.

The mid/lower snowpack is generally well settled and strong.

Snowpack depth ranges between 100 to 250 cm at treeline elevations.

Weather Summary

Cloudy. 1 to 2 cm of snow at treeline. 30 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

Tuesday
Mix of sun and clouds. 30 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2600 m.

Wednesday
Mix of sun and clouds. 1 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 6 °C. Freezing level 2900 m.

Thursday
Sunny. 40 km/h southwest ridgetop wind. Treeline temperature 8 °C. Freezing level 3200 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening 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.

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.
