Highlights

As we head into a week of very cold temps the danger rating is expected to remain as is. Watch for increasing wind creating fresh slabs at high elevations. Be mindful of the basal weaknesses when committing to larger terrain features.

    Surprisingly little wind effect in the Emerald Lake region today. However, the 20cm low density storm snow is available for transport when the wind decides to pick up. Be watchful at a local level for increasing wind and associated slabs.

    A well settled midpack overrides a weaker facetted base. This weak base is found most places except the west side of the divide. Beware of steep shallow snowpack areas (where the likelihood of triggering this basal layer is highest).
