  Strong winds and moderate, warm precipitation has made for rapid formation of windslabs which has increased the danger. These windslabs are very susceptible to human triggering and will likely step down to the basal depth hoar.

  Windslabs 60-100cm thick sit over weak basal depth hoar. Limited observations because of storm, but suspect natural avalanche cycle due to added load on this layer.
