Hard wind slabs may be stubborn to trigger. With shifting winds, the most recent and reactive slabs are likely on south and west aspects formed by outflow winds.
In a sea of wind affected surfaces, lingering wind slabs remain a concern and may be tricky to recognize.
Avoid large open slopes capable of producing large avalanches.

No recent avalanche activity has been reported.
With limited loose snow remaining for transport, natural avalanches are unlikely. Human-triggered avalanches remain possible.
Reports in this region are limited, please post any photos or observations to the MIN if you head out!
Outflow winds have sculpted the snowpack. Wind scoured, or hard snow surfaces exist in exposed terrain, while wind slabs have formed in lee or cross loaded features.
The January 26 crust is buried 50–100 cm deep below 1350 m. Surface hoar may linger above this layer on sheltered north to east aspects. Human triggering is considered unlikely.
Facets or depth hoar exists at the base of the snowpack and may be a concern in areas with a shallow snowpack.
