Avalanche Summary

No avalanches have been reported. Please let us know what you're seeing out there.

Snowpack Summary

Welcome to winter! As we begin our forecasting season, we are working with limited information from the field. Early reports suggest there's enough snow for avalanches at alpine elevations in some places. Recent snow is likely to have been redistributed into slabs on lee slopes at alpine elevations. This snow may overlie a weak old snow surface (surface hoar, facets and/or a crust) which developed during the recent dry spell. Check the bond of the snowpack at this level and take a cautious approach as new snow builds deeper above this layer.

Avalanche Problems

Storm Slabs

New snow is building up over a potentially weak old surface interface. Changing winds may leave wind slabs on a variety of slopes.

Be cautious as you transition into wind affected terrain.>Caution around convexities or areas with a thin or variable snowpack.>Early season hazards such as rocks, trees and stumps are still visible.>

Aspects: North, North East, East, South East, South, South West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
