Regions

South Coast, Powell River, Tantalus, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron.

Isolated pockets of wind slab may be found in the high alpine on north through east aspects. Monitor the conditions and back off steep slopes as the surface becomes wet or slushy.

Confidence

Moderate

Avalanche Summary

There have been no recent reports of avalanches in the region. Small and isolated wet loose avalanches may be seen in steeper terrain with sunshine and warming.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Snowpack Summary

The surface snow is likely wet due to warm temperatures and rising freezing levels to mountain top.

North through east facing slopes in the alpine may have new surface hoar development and hold dryer snow (10 to 30 cm) which sits over moist snow. At treeline, 10-15 cm sits above a firm rain crust. Below the crust is a rain-soaked snowpack.

Snow depths at treeline vary across the region from 65 cm to 150 cm.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.
