Regions

Coquihalla, Harrison-Fraser, Manning, Skagit.

Wind slab formation has been extensive and could extend into openings below treeline.

Avoid slopes that have been wind loaded.

Confidence

Moderate

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

Avalanche Summary

No new avalanches have been reported. However, observations are currently very limited.

Snowpack Summary

15 to 25 cm of recent snow and extreme southwest wind have formed wind slabs in open areas at all elevations. The recent snow overlies a persistent weak layer.

At treeline and above, this layer is primarily a hard crust with weak facets above and/or below.

In sheltered treeline locations and below, this layer may be a combination of hard crust and/or surface hoar.

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

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

Weather Summary

Saturday Night

Monday
Cloudy. 3 to 10 cm of snow above 1400 m (rain below). 50 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

Tuesday
Mostly cloudy. 40 km/h southwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2800 m.

Terrain and Travel Advice

  • Keep your guard up at all elevations. Wind slab formation has been extensive and could extend into openings below treeline.
  • Avoid freshly wind-loaded terrain features.
  • Be alert to conditions that change with elevation and sun exposure.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.
