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.

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.
