Regions

Coquihalla, Harrison-Fraser, Manning.

Loose avalanches may start small but can quickly grow and push you into hazardous terrain. Stay alert to changing conditions as you gain elevation.

Confidence

Moderate

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

Avalanche Summary

No new avalanches have been reported since Saturday. Natural activity has likely decreased, but wet loose avalanches may still be triggered in steep terrain.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

The rain continues to saturate the upper snowpack. There is 80 to 100 cm in the alpine and 20 to 40 cm at lower elevations, overlying a series of early March melt-freeze crusts.

A crust with facets may exist 100 to 200 cm below the surface, primarily on northerly aspects at higher elevations. This layer appears unreactive but continues to be monitored.

The mid and lower snowpack is otherwise strong and well settled.

Weather Summary

Thursday Night

Cloudy. 15 to 30 mm of rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2400 m.

Friday

Cloudy. 30 to 35 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 2000 m.

Saturday

Mostly cloudy. 1 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -5 °C.

Sunday

Mix of sun and clouds. 2 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Keep in mind that the high density of wet avalanches can make them destructive.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
  • Be alert to conditions that change with aspect and elevation.

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.
