Snowpack Summary
Incoming new snow is building fresh storm slabs and is falling on a persistent slab made up of 3 weak interfaces in the top 30 to 50cm of the snowpack. Depth and distribution of these weak surface hoar/facet layers varies within the terrain; although buried surface hoar has consistently been found in sheltered features at TL.
Avalanche Summary
Avalanche control on Parkers Ridge Friday produced 2 large avalanches, size 2 and 2.5 on a N aspect running as the the persistent slab. On the 18th of 18 shots placed, a large crown appeared up to 1.5m thick x 150m long x 300m wide - interesting display of the variability in sensitivity and spacial distribution of buried weaknesses.
Confidence
Intensity of incoming weather systems is uncertain
