Regions

South Coast, Powell River, Tantalus, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron.

Say "Aloha" to the pineapple express! Heavy rain and high freezing levels will continue to soak the snowpack.

Danger will be highest during periods of heavy rain.

Confidence

Moderate

Avalanche Summary

Observations from alpine terrain in this forecast region have been limited. We suspect that natural avalanches have been occurring at high elevations where precipitation has been falling as snow.

Snowpack Summary

In high alpine terrain recent precipitation may have fallen as snow and formed storm and wind slabs. At treeline the majority of recent precipitation has fallen as rain, with fluctuating freezing levels a mix of heavy snow and crusts could be found. Below treeline the snowpack is saturated and disappearing.

Terrain and Travel Advice

  • Choose conservative terrain and watch for clues of instability.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.

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.
