    Low probability, high consequence problem at the moment.

    Use caution around thin to thick areas as potential trigger locations. Keep an eye out for buried surface hoar lurking in isolated sheltered locations below treeline.

Weather Forecast

Wednesday morning, expect sunny periods and isolated flurries in the afternoon with only a trace, up to ~4cm of new snow. Alpine temperatures: Low -15 C, High -8 C.

Snowpack Summary

Surface faceting continues with cooler temperatures. Previous winds have stripped snow from all exposed terrain creating hard wind slabs and wind affected snow in any open terrain. The mid-pack is supportive. Decomposing surface hoar is found down 40cm to 80cm in isolated sheltered locations.
