Snowpack Summary

New snow (up to 40cms in 24 hours) is expected to arrive starting late Sunday afternoon and will bury the 15 cm of settling snow from Friday's storm. Sustained southerly winds are building small wind slabs on north-facing slopes in the lee of exposed features. Friday's snow buried a variable interface composed of faceted (sugary) snow and old hard wind slabs (especially at higher elevations). Recent reports suggest the snow has bonded fairly well to this interface; however, it remains a concern as a sliding layer during the next storm. The mid and lower snowpack are well settled and stable.
