Wind slabs may be triggerable on lee slopes near ridgetops.
For the best and safest riding conditions, seek out sheltered terrain with no wind effect.
Recent snow and strong southwesterly winds built wind slabs on lee slopes. These slabs are starting to bond, but may need another day or two. Remain extra cautious around wind-loaded features, especially near ridgetops.
On Tuesday, a skier accidentally triggered a small size 1 storm slab on an east-facing slope below treeline. Other reports of cracking and reactivity in the recent storm snow have also come in the last couple of days.
There have been limited observations from this area. If you’re heading out, please consider sharing details about what you experience on the Mountain Information Network.
40 to 60 cm of settling storm snow is currently covering a thick melt-freeze crust that exists up to around 2000 m and on all solar aspects. In isolated, sheltered areas, a layer of surface hoar may exist on this crust. Previous strong southwesterly winds blew the storm snow into wind slabs on lee north and easterly slopes.
A layer of surface hoar/facets/crust, is buried 80 to 100+ cm. Triggering this layer is considered unlikely at this time.
