Regions

South Coast, Powell River, North Shore, Sasquatch, Tetrahedron, Skagit.

Although the high avalanche hazard has passed, remain cautious and assess the stability of the surface snow before committing yourself to avalanche terrain.

Confidence

Moderate

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

Avalanche Summary

The avalanche cycle has likely slowed due to the precipitation that has already fallen. Natural avalanches are likely in the high alpine above the rain line.

If you are going into the field, please support the forecast by posting a MIN.

Snowpack Summary

Except for the highest alpine peaks, expect the upper snowpack to be saturated down to the thick, widespread crust, buried in early March. Below it, the snowpack is generally settled and well-bonded.

Weather Summary

Friday

Cloudy. 35 to 75 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 1900 m.

Saturday

Mix of sun and clouds. 2 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.

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.
