Snowpack Summary
10 to 20 cm of snow accumulated through the last week. This overlies a melt-freeze crust on southerly aspects, perhaps small surface hoar crystals on shaded aspects, and otherwise 20 cm of snow from the weekend. This recent snow has generally been stabilizing, but there could be some wind slabs that linger at higher elevations. All of this recent snow sits above a widespread crust, with the exception of high north-facing terrain.
Terrain and Travel
- Be careful as you transition into wind affected terrain.
- Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
