<p>Storm day on Seymour. Heavy high density precipitation (graupel) and mod-strong SE wind for most of the day. Reactive top 15-20cm composed of the last 24hrs of storm snow sliding on the snow that had fallen over the days previous. Both naturals and skier triggered size 1s. Slabs would easily propagate. Nothing stepping down to deeper layers. Overall pleasant skiing!</p>
