Snowpack Summary

The freezing level on Friday was hovering around 2200m in most areas. Slight cooling overnight coupled with mostly cloudy skies will likely result in the formation of a thin surface crust that will break down during the day on Saturday. At higher elevations, new snow and wind have likely formed small wind slabs and cornices remain large and looming. The snowpack is well settled and continues to transition into a spring snowpack. The bottom third of the snowpack is composed of weak facets, but this deep persistent weakness has not been reactive for a few weeks.
