Wind slabs may be found on atypical slopes due to strong northeast wind. Assess for slabs before committing to high-consequence terrain.
The best riding will be in terrain sheltered from the wind where recent snow remains soft.

We haven't received any new reports of avalanches since Saturday, when a few large (size 3) wind slabs avalanches were triggered on southwest aspects at treeline and alpine elevations.
Looking forward, it remains possible for riders to trigger wind slab avalanches at higher elevations.
Strong northeast winds redistributed the 15 cm of snow that accumulated since last Thursday. This snow may remain soft in wind-sheltered terrain at lower elevations and it overlies weak faceted grains and/or surface hoar crystals.
Faceted grains overlie a hard melt-freeze crust around 50 to 90 cm deep that formed mid-January.
The lower snowpack is consolidated.
