Snowpack Summary

Wind slabs and storm slabs continue to build above a weak facet layer which formed during the brutal cold of mid-January and was buried around January 20th. Rising temperatures and snowfall during the weekend will increase the likelihood of storm slab and wind slab avalanches, which could be very large. In shallow snowpack areas, a weak, "rotten" snowpack has been observed.
