Regions

South Coast, North Shore, Tetrahedron.

Strong solar radiation will likely impact the surface snow.

Watch for unstable snow on steep terrain features, especially when the snow is moist or wet.

Confidence

High

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

At lower elevations, a moist snowpack or a surface crust is found. At higher elevations, up to 15 cm of snow has accumulated over a crust or moist snow. Snow surface of high north-facing alpine slopes remains dry.

Weather Summary

Thursday Night

Partly cloudy. 15 to 25 km/h northeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1200 m.

Friday

Mostly sunny. 15 to 25 km/h northeast ridgetop wind. Treeline temperature +3 °C. Freezing level rising to 1500 m.

Saturday

Cloudy with 2 to 4 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1000 m.

Sunday

Cloudy with 2 to 4 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1000 m.

Terrain and Travel Advice

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

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.
