In recent days, a few skier triggered wind slabs size to 1.0 were reported at treeline and in the alpine.

In most areas there is 30-50 cm of recent low density storm snow that has stayed unconsolidated except where it has been transported into wind slabs. The surface snow has been facetting due to the cold temperatures, and some surface hoar has been developing in isolated areas. The mid-pack has been reported to be well settled above above a crust that was buried in mid-november. This crust may be buried less than a metre to close to 2 metres deep, depending on elevation and previous exposure to winds. Snowpack tests on the crust have shown variable results from sudden to no result. Professionals continue to monitor this crust and are watching for facet development above and below that may increase reactivity. The basal layers of the snowpack continue to be reported to be moist in some of the deeper snowpack areas of the region.
