Avalanche Summary

New snow and wind will mean that storm slabs are likely forming and chances are good that they will become more reactive throughout the day on Thursday.

Snowpack Summary

5-10 cm of new snow from Wednesday right likely sits on a weak layer of feather surface hoar. Another 5-15 cm is expected throughout the day, bringing total new snow amounts to 10-25 cm. The middle of the snowpack contains a mix of hard crusts and facet/crust layers. Snowpack depths remain very shallow throughout the region with about 75-100 cm at upper treeline elevations. Below treeline terrain is below the threshold for avalanches.
