Yesterday's storm presented a unique avalanche forecasting problem. Even though 15-16 inches of new snow fell, it fell on a very shallow snowpack- there was not enough snow to link turns. The added snow created more of a base but rocks, logs and terrain features are still visible. Today's snowpack resembles what we would find in November- except it is late winter.
There was very limited data available to assign the Considerable danger rating. The reasons I went with the more conservative danger rating are related to my observations and reports of collapse, cracking, and poor snow structure due to the new load of 2-3.5" of new snow plus the additional effect of wind loading.
