In sintesi

With up to 35cm of storm snow in isolated locations, very little natural activity was noted and visibility was excellent. Don't be lulled into false sense of security as many slopes may be awaiting the human trigger.

    Anywhere from 5-35cm of new snow fell Saturday evening. It appears to be bonding well as winds were light and temperatures warm when storm arrived. Winds are just now slabbing the storm snow.
