Avalanche Summary
Recent reports indicate a few cornices in the alpine triggering windslabs on slopes below to size 2.5 on east and west aspects.
Snowpack Summary
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.
Problems
Wind Slabs
Wind slabs are reported to exist in the alpine. Watch for conditions that change with aspect and elevation.
Be cautious as you transition into wind affected terrain.Dig down to find and test weak layers before committing to a line.The recent snow may now be hiding windslabs that were easily visible before the snow fell.
Aspects: All aspects.
Elevations: Alpine.
