Regions

Sea To Sky, South Coast Inland, Brandywine, Garibaldi, Homathko, Spearhead, Tantalus, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Wet loose avalanches are possible on steep sun-exposed slopes. Give cornices a wide berth from above and below.

Where a thick surface crust exists avalanche activity will be unlikely.

Confidence

High

Avalanche Summary

No recent avalanche reports by 4 pm on Wednesday. Sunshine and rising temperatures may weaken the surface snow and initiate small wet loose avalanches on southerly-facing slopes. Use caution on north-facing slopes in the alpine as they may host pockets of wind slab.

If you head into the backcountry, please submit any observations or photos to the Mountain Information Network, observations are limited in the spring.

Snowpack Summary

A widespread surface crust likely exists at all elevations, except on high north-facing slopes where pockets of wind affected dry snow exist 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

Wednesday Night

Clear with a few lingering clouds. 20-30 km/h north ridgetop wind. Treeline temperatures near -6°C. Freezing valley bottom.

Thursday

Sunny. 15-20 km/h northeast ridgetop wind. Treeline temperature -2°C. Freezing level near 1600 m.

Friday

Sunny. 25 km/h southeast ridgetop wind. Treeline temperature +1°C. Freezing level near 1900 m.

Saturday

Cloudy with new snow/ rain 3 to 10 mm. 10-15 km/h southeast ridgetop wind. Treeline temperature +2°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.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • 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.
