The ongoing wind continues to build wind slabs, and they are likely to be more reactive where they are forming over a crust. Make conservative terrain choices and avoid overhead hazards.
Strong winds will continue to redistribute recent storm snow building wind slabs in exposed terrain. Wind slabs will be more reactive where they are forming over a crust.
As we transition into a cooler, stormy period we expect to see wind slab avalanches remain active.
These avalanches will be more reactive where they are forming over the most recent crust.
Approximately 20 cm of recent storm snow overlies a melt-freeze crust that extends up to 2000 m.
Ongoing winds are redistributing this unconsolidated snow, building new wind slabs in exposed terrain.
A layer of surface hoar, facets and/or a crust exists around 100 cm deep. This layer appears to be improving but may still be present in high alpine terrain. In thin snowpack areas, faceted grains or depth hoar may exist at the base of the snowpack.
