Use caution in upper elevation areas today. Northerly slopes contain deeper snowpacks and multiple weak layers including buried surface hoar and basal facetscreating a VERY weak snowpack in some areas. New windslabs formed in the last 24 hours on NW, N and NE slopes. With multiple weak layers, widespread variability and newly created wind slabs, avalanche season has begun. We will be collecting more data over the next few days and begin issuing advisories next week.
