Avalanche Summary
An impressive natural cycle of slab activity to size 3.5 took place on Thursday with many features running full path. Loose wet activity to size 2 was also observed in terrain that was more rain-affected.
Snowpack Summary
Strong southwest winds, heavy snowfall, and warm temperatures in recent days have formed deep and cohesive storm slabs at treeline and above. Widespread cornice development has also taken place. At lower elevations heavy rain has continued to penetrate the snowpack. The recent storm snow overlies a weak layer of surface hoar or a sun crust that were buried on March 10th. Some areas had strong winds before the surface hoar was buried, so its distribution may be specific to sheltered and shaded terrain features. Some professionals are still expressing concern for the buried layer of surface hoar from February 12th that is now down more than 1.5m in most places. Although unlikely, the new load of snow and wind may overload this deeply buried weak layer in isolated, unsupported terrain.
