Regions

Sea To Sky, Brandywine, Garibaldi, Homathko, Spearhead, Tantalus, Sky Pilot.

It's a good time to consider stepping out into more complex terrain.

Riding conditions will be best once the surface crust has softened on sun-affected slopes.

Avalanche Summary

Loose wet avalanches were reported on Saturday and Sunday from steep sun affected slopes. Recent cornice failures were also reported. We expect this activity to continue while temperatures remain warm and there is strong sunshine.

If you are headed into the backcountry please consider submitting a MIN report.

Snowpack Summary

Strong sunshine and warm temperatures are expected to break down the surface crust - or moisten surface snow at low elevations, and on steep sun affected slopes into the alpine. Snow on north facing alpine slopes will likely remain dry.

Check out this MIN from the Spearhead.

The mid and lower snowpack are generally well-settled with no current layers of concern.

Weather Summary

Monday Night

Clear skies. 5 to 10 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 3400 m.

Tuesday

Sunny. 20 to 30 km/h northwest ridgetop wind. Treeline temperature 3 °C. Freezing level 3400 m.

Wednesday

Sunny with late afternoon cloud. 40 to 50 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing levels start at 2000 m and drops over the day.

Thursday

Cloudy. 30 to 40 km/h southwest ridgetop wind. Treeline temperatures around -3 °C. Freezing levels remain around 800 m.

Terrain and Travel Advice

  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.

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.
