Lo esencial

Shooting cracks were observed on low angle terrain BTL to TL up to 2100m failing on FC/SH weakness. This layer will persist for sometime and its exact distribution is uncertain. "Considerable" is when most accidents happen so use extra vigilance.

    Natural avalanche activity has declined but the buried SH/FC layer anywhere from 50-80cm down remains touchy. Cracking and whumphing still occurring BTL to TL. Slopes that did not slide with last Monday's 50cm storm should be highly suspect.

    Tamaño

    Snow pulses have deposited 35cm in last 3 days. Another 10-15 cm is expected into Monday. The snow will cumulate into a storm slab adding load to the SH layer. Initiating a small slide has the potential to step down to this weakness.
