Kernpunkte

Avalanche danger will rapidly increase when snowfall changes to rainfall.

Cautious travel is advised as the snowpack remains shallow in many areas.

Avalanche Summary

No avalanches have been reported. However, observations are limited.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

New snowfall may not bond well to old snow crystals, including: surface hoar, sugary facets, and sun crusts. It's estimated that anywhere from 15 to 35 cm of new snow will have covered this layer.

Above treeline, there is a buried crust down 40 to 60 cm, which extends to the ground. The snowpack is around 70 to 90 cm deep at treeline, and diminishes rapidly below treeline.

In wind exposed areas, soft snow has likely been redistributed into lee features and formed wind slabs.

Terrain and Travel Advice

  • Avalanche danger will rapidly increase if snow switches to rain.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be cautious of buried obstacles, especially below treeline.
