Take time to identify potential areas of wind-affected snow before moving into steep terrain.
Small and isolated wind slabs could linger at upper elevations.
Small wind slabs may exist in isolated lee features where they overlie a thick crust. Watch for unstable snow on steep and unsupported slopes where human triggering may be possible.
No new avalanches have been reported in this region.
5 to 10 cm of snow now overlies the late January surface hoar/crust layer. This new snow has been accompanied by strong to extreme west wind, meaning that the crust is still on the surface on southerly aspects and deeper deposits will be found on east aspects.
The surface is moist at lower elevations. The mid and lower snowpack is well settled.
