Minimal freeze over the past few days combined with rain has caused numerous loose wet slides on all aspects just barely reaching into the Alpine. Some of these loose slides are stepping down and pulling out deep wet slabs at lower elevations.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Likely

Expected Size

1 - 4

Deep Persistent Slabs

"Warm days" are re-awakening some of the deeply buried weak layers at the base. There has been recent activity on this layer. These slides are proving to be very destructive taking out mature timber at the base of there normal runouts.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood
