Fresh snow! ...and wind. Expect to find more reactive deposits in wind-loaded areas and a more widespread problem as snowfall accumlates.
Up to of 20 cm fresh snow is forecast to accumulate alongside a strong southwest wind. Expect to find deeper and more reactive deposits around ridges and lee features.
No new avalanches have been reported.
Cornices are big, give them space both above and below, and expect large cornices to be fragile, especially with loading or daytime warming.
Up to 20 cm fresh snow on Saturday alongside strong southwest wind.
Under this new snow, a widespread crust covers most surfaces at lower elevations and sunny aspects into the alpine. Cold, dry snow remained on shady aspects at upper elevations, and recent winds redistributed and pressed available snow into northerly aspects.
Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth.
In some areas, particularly in the Haines Summit, a weak layer of facets or surface hoar is buried 50-80 cm. This layer is unlikely to trigger from the weight of a rider, but concern exists with very large loads like cornice falls.
