In sintesi

Tonight's storm may bring 15-20cm of snow across the region, perhaps more on the west side of the Divide. Winds are expected to be strong from the SW, with temp's moderating to seasonal values. We expect a natural avalanche cycle with this new snow.

    Climbers should avoid Cascade Falls and Rogan's Gully this weekend. There is a large amount of snow above these routes and with the coming storm and warm temp's, natural avalanches will threaten routes with large bowls above.

    The recent cold snap has faceted out the surface snow, creating a weak base for the incoming storm snow. Winds are forecasted to be moderate to strong from the west, so we could see fast development of storm slabs on a weak, sugary base.

    There is a weak, faceted base found in most places except the west side of the divide. Many thin, trigger spots exist in the alpine and treeline due to strong winds. Click our Facebook link below to see images of recent basal failures near Sunshine.
