Avalanche danger will rapidly increase when snowfall changes to rainfall.

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

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.

A mix of new snowfall and rainfall will rapidly settle the upper snowpack, and presents as a slab. Its likely the new snow will not bond well to old snow crystals, including: surface hoar, sugary facets, and sun crusts. It's estimated that anywhere from 35 to 55 cm of new snow will have covered this layer.

Above treeline, there is a buried crust down 60 to 80 cm, which extends to the ground. The snowpack is now around 100 to 120 cm deep at treeline, and diminishes rapidly below treeline.

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

Friday Night
Cloudy. 20 to 75 mm of precipitation as snow or rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1500 m.

Saturday
Cloudy. 10 to 35 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1400 m.

Sunday
Mostly cloudy. 10 to 25 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1500 m.

Monday
Mostly cloudy. 20 to 55 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

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