Regions

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

Take care around ridgelines where wind slabs may linger.

Minimize your exposure to sun affected slopes. Sunshine and rising temperatures will increase the potential for wet avalanches.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in this region over the past few days. However, field observations are currently very limited.

If you head into the backcountry, please submit any observations or photos to the Mountain Information Network, observations are limited.

Snowpack Summary

Up to 10 cm of settling storm snow sits over old snow surfaces, and a crust on sun affected slopes. On north facing slopes near ridgelines, deeper deposits of snow can be found - while south facing slopes may hold hard, wind pressed surfaces or a crust.

Below treeline elevations have minimal snow cover, if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

Problems

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.

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.
