Points saillants

The Pineapple Express prevails! The snowpack, or rather "slushpack", continues to be soaked by heavy precipitation.

    Wet loose avalanches will be possible in steep terrain where the snow surface is wet. They will be largest at treeline and alpine, where precipitation had initially fallen as snow and now is being soaked by rain.

High

Avalanche Summary

Observations from alpine terrain in this forecast region have been limited. We suspect that natural wet avalanches have been occurring at all elevations.

Snowpack Summary

The snowpack is becoming fully saturated with water as heavy rain continues to fall. Below treeline the snowpack is disappearing.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
