    New snow and wind will create new, reactive storm slabs.

Avalanche Summary

A natural avalanche cycle is expected to occur throughout the duration of this storm.

Over the past few days, several size one wind and storm slab avalanches have been reported on all aspects and elevations.

Snowpack Summary

20 to 30 cm of new snow is burying a previously faceted and wind effected surface. New snow is expected to bond poorly to the previous surface.

The snowpack remains generally deep, with few layers of concern. Treeline snow depths exceed 300 cm.
