Wind is the major weather factor to keep a close eye on this weekend. Even moderate wind speeds can quickly build fresh wind slabs reactive to human triggers.

Snowpack Summary

The snow that fell last weekend has seen little wind effect in many areas throughout the region. If winds pick up this weekend, freshly formed wind slabs will be the primary concern. The mid pack is reported to be well settled. There is sufficient snow on the ground for avalanches at treeline and alpine elevations, and possibly in some below treeline locations. Reports suggest typical treeline snow depths are around 110-150 cm, but a report from the east side of region indicated a much lower snow depth of around 90 cm. Limited reports suggest the crust from the middle of November is down 50-80 cm and the crust from early November is down 80-110 cm.
