As you move above the rain crust, investigate the bond of the recent snow to the layers below.

Confidence

Moderate

Avalanche Summary

We haven't received any reports of recent avalanche activity.

Please consider posting a MIN if you head into the backcountry.

Snowpack Summary

A rain crust may have formed over around 40 cm of storm snow from earlier this week.

A layer of surface hoar and/or faceted grains and a hard melt-freeze crust from mid-November sit in the middle of the snowpack. Weak faceted grains may extend to the base of the snowpack, particularly in areas where the snowpack is thin.

Snow depths at treeline vary from about 50 to 100 cm and decrease rapidly at lower elevations.

Weather Summary

Thursday Night
Mostly cloudy with 3 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -6 °C.

Friday
Cloudy with 5 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Saturday
Mostly cloudy with 5 to 15 cm of snow turning to rain. 40 to 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2600 m.

Sunday
Mix of sun and cloud with 1 to 2 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 2000 m.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Be careful as you transition into wind-affected terrain.
  • Be cautious of buried obstacles, especially below treeline.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
