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 and some treeline elevations. 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.
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. Watch out for snow that feels punchy, breakable or stiff - this may indicate a wind slab.
Caution around convexities or areas with a thin or variable snowpack.>Avoid freshly wind loaded features.>
Aspects: All aspects.
Elevations: Alpine.
