Another day with warmer temperatures up high, caution on solar aspects in the sunshine.The winter permit system comes into effect today, click here Winter Permit Information for further details.

Weather Forecast

We are still under the influence of a  high pressure ridge bringing light winds and nil precipitation. Temperatures are still warmer up high and will hover around 0 degrees at 2000m. This pattern is expected to last until Thursday when light snow is expected

Snowpack Summary

Snow pack has settled quite a bit since the storm exposing more early season hazards. There's sun crust on south aspects. November 12 surface hoar layer is down between 50-110cm at higher elevations.

Avalanche Summary

One size 2 natural avalanche in the east of the Rogers Pass summit in highway corridor from Mt Macdonald.

Confidence

Due to the number and quality of field observations

Avalanche Problems

Persistent Slabs

A buried surface hoar layer is buried down 50 to 110cm. Riders can trigger this layer from shallow snowpack areas with large consequences. Caution on planar surfaces at higher elevations which have not previously slid
Avoid convexities or areas with a thin or variable snowpack.Dig down to find and test weak layers before committing to a line.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3
