Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Avalanche danger remains high above the rain line. It is still possible to trigger wet loose avalanches at treeline elevations.

Confidence

Moderate

  • We are uncertain about how the snowpack will react to the forecast weather.
  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

Several natural and human-controlled slab and wet loose avalanches were reported since Monday, up to size 1.5.

If you're going into the backcountry, please share your observations and post a MIN.

Snowpack Summary

High elevation snowfall combined with strong south to southwest winds is actively loading lee terrain. A rain line between 1900 to 2100 m has likely saturated recent storm snow at mid and lower elevations.

The early March crust is now buried 80 to 120 cm deep, though it remains highly variable and may be as shallow as 20 cm in some areas.

Below this, the lower snowpack is generally well settled and strong.

Weather Summary

Thursday

Cloudy. 4 to 15 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1800 m.

Friday

Mostly cloudy. 5 to 35 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1800 m.

Terrain and Travel Advice

  • Be alert to conditions that change with aspect and elevation.
  • Avoid lee and cross-loaded slopes in the alpine.
  • Loose avalanches may start small, but they can grow and push you into dangerous 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.
