Regions

South Coast, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron.

Low danger doesn't mean no danger.

Watch for changing snow and wet loose avalanches on steep, sun-exposed slopes. Where a thick crust exists avalanches are unlikely.

Confidence

High

Avalanche Summary

No recent avalanche reports by 4 pm on Tuesday. Sunshine and rising temperatures may weaken the surface snow and initiate small wet loose avalanches on southerly-facing slopes.

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

Watch for moist, unstable snow on southerly slopes with sun and warm temperatures. Wind-affected dry snow may exist on north-facing alpine slopes - watch for reactivity here. Where a crust exists expect limited avalanche activity.

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 with cloudy periods. 10-25 km/h northeast ridgetop wind. Freezing level 1000 m by the morning.

Wednesday

Sunny. 10-30 km/h northerly ridgetop wind. Treeline temperature +6 °C. Freezing level near 1600 m.

Thursday

Sunny with cloudy periods. 15-25 km/h northerly ridgetop wind. Treeline temperature +4 °C. Freezing level around 1700 m.

Friday

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

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • 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.
