Wet loose avalanches will be possible in steep terrain with warm temperatures and the potential for periods of strong sun. Avoid steep slopes if the snow surface becomes moist or wet.

Confidence

Moderate

Avalanche Summary

Numerous wet loose avalanches were reported on Friday with rain and warm temperatures.

Wet loose activity will be possible on Monday as temperatures rise and the potential for periods of strong sun could destabilize the upper snowpack. Watch for changing conditions throughout the day.

Please continue to post your observations and photos to the Mountain Information Network.

Snowpack Summary

15-30 cm of moist new snow overlies an unsupportive crust. The remainder of the snowpack is moisture-saturated and isothermal to the ground. If temperatures cool, a crust may be found on the snow surface.

Treeline snow depths are roughly 150 to 200 cm.

Terrain and Travel Advice

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Loose avalanches may start small but they can grow and push you into dangerous terrain.
  • Keep in mind that wet avalanches can be destructive due to their high density.
