Snowpack Summary
5-10 cm of new snow likely sits on a mix of melt-freeze crusts, hard wind slabs, sugary faceted snow, and feathery surface hoar crystals depending on location. Continued snowfall and high winds are expected throughout the day, bringing total new snow amounts to approximately 15-20 cm by the end of the day. Storm slabs will likely be reactive. Total snowpack depth ranges from 50-100 cm and tapers rapidly at lower elevations.
