Regions

Sea To Sky, Brandywine, Garibaldi, Homathko, Powell River, Spearhead, Tantalus.

Wet loose avalanches are possible on steep sun-exposed slopes. Where a thick surface crust exists avalanche activity will be unlikely.

Give cornices a wide berth from above and below.

High

Avalanche Summary

No recent avalanche reports by 4 pm Tuesday.

Solar radiation and warming may initiate small, isolated wet loose avalanches on sun-exposed slopes. Pockets of wind affected snow may linger on high north-facing slopes. Where a thick surface crust exists avalanche activity is unlikely.

Snowpack Summary

A widespread surface crust likely exists at all elevations, except on north-facing slopes which is expected to limit avalanche activity. Wind-affected dry snow still exists on north-facing alpine slopes above 2000 m. Watch for moist, unstable snow on southerly slopes with sun and warm temperatures.

Below treeline elevations have minimal snow cover, if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.

Weather Summary

Tuesday Night

Clear. 10-25 km/h northeast ridgetop wind. Treeline temperatures near -5 °C. Freezing level valley bottom.

Wednesday

Sunny. 10-30 km/h northerly ridgetop wind. Treeline temperature -2°C. Freezing level near 1600 m.

Thursday

Sunny. 20-30 km/h northerly ridgetop wind. Treeline temperature -2°C. Freezing level around 1600 m.

Friday

Sunny. 10-20 km/h easterly ridgetop wind. Treeline temperature +1°C. Freezing level 2100 m.

Terrain and Travel Advice

  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • Caution around slopes that are exposed to cornices overhead.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.

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.
