Sea To Sky

New snow is burying a potential weak layer. Test how the new snow is bonding before increasing your exposure.

Travel cautiously, as the snowpack is shallow and hides thinly buried hazards.

No new avalanches have been reported since Friday. However, information is limited.

New snow will be falling on a variety of potentially weak crystals, including: surface hoar, facets, and sun crusts on steep south facing slopes. The new snow may not bond well to the old surface.

A firm crust that formed in early November can be found 30 to 100 cm deep in the alpine and at treeline. Weak, sugary facets have been spotted above and below the crust. This layer isn't currently a concern, but once more snow arrives it could produce avalanches.

Expect to find 50 to 150 cm of snow, treeline and above, with snowpack depth decreasing rapidly below 1600 m.

Monday Night
Cloudy with up to 5 cm of snow. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1200 m.

Tuesday
Mix of sun and cloud. 20 km/h north ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Wednesday
Mix of sun and cloud. 10 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 900 m.

Thursday
Cloudy with 10 to 25 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

• Use small, low consequence slopes to test the bond of the new snow.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• Be cautious of buried obstacles, especially below treeline.
