New snow and wind continue to build wind slabs at upper elevations.
Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
New storm snow and wind will continue to build new wind slabs over older wind slabs that are likely to linger where they have built over a melt freeze crust. Recent shifting wind direction built wind slabs on most slopes at treeline and above.
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.
Accumulated storm snow is roughly 20 to 40 cm and sits on a melt-freeze crust that extends up to 2000 m.
The surface snow has been heavily impacted by wind in open terrain features.
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.
