Avalanche Summary
On Friday, ski cutting produced several loose dry avalanches running size 1 in the new snow and running long and fast. The poor bond between the new snow and the old snow interface could become a problem when the next storm arrives. Expect avalanche activity to increase with the incoming storm.
Snowpack Summary
New snow is expected to arrive Sunday afternoon and 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. Recent reports suggest the snow has not bonded well to this interface, which means it could become a sliding layer during the next storm. The mid and lower snowpack are well settled and stable.
