Snow is available for transport and strong wind speeds are in the forecast.
New wind slabs will be building over older wind slabs and may be found is atypical terrain.
Strong wind from the northwest over the weekend developed wind slabs in direct lees, a switch to a more typical wind direction may see the development of fresh wind slabs directly lee of ridges and high points.
At upper elevations, where the crust is thinner or not present, it may still be possible to trigger persistent slabs on multiple buried weak layers of surface hoar and/or crusts in the top 120 cm of the snowpack.
On Saturday, numerous wind slab avalanche were reported. These avalanches were between size 1 to 2 and were naturally and rider triggered.
Roughly 30 to 50 cm of recently accumulated snow and strong variable winds have formed wind slabs in lee terrain features at treeline and above. As winds switch to a more prevailing direction expect fresh wind slabs to form.
Below this is a 1 to 10 cm thick crust on all aspects. The thickness of the crust depends on elevation.
At upper elevations, where the crust is thinner or not present, it may still be possible to trigger persistent slabs on multiple buried weak layers of surface hoar and/or crusts in the top 120 cm of the snowpack.
The mid/lower snowpack is well settled and strong in most areas.
