After a dry first three weeks of January, and limited snowfall through Oct, Nov, and Dec, the underlying snowpack was very weak and faceted. Approximately 32" of snow and 2.5" SWE fell between Jan 22-30, with the last 8"-12" (.6-1.0" SWE) falling on the night of the 30th. A three day period of sustained 25-35 mph southerly winds occurred mid-week, in between storm systems. Several natural avalanches have occurred during this period.
