Snowpack Discussion
Up to 80cm of new snow since Saturday with periods of strong to extreme SW winds has formed a widespread storm slab at all elevation bands. This slab is bonding poorly to our previous drought layer of old breakable crust & widespread surface hoar. This interface is reactive in snowpack testing & could easily be human triggered.
Twopersistent weak layers (PWL)from Jan/Feb are now buried well over a meter. Large triggers such as storm slab avalanches may step-down to this layer
Avalanche Activity
Natural activity is starting to tapper off but human triggering remains likely.
A large natural avalanche cycle (up to size 3.5) began overnight Saturday with numerous avalanches reaching the ends of their runouts.
Artillery control Sunday night produced avalanches up to size 4.
A group up the Asulkan Valley triggered a size 2 avalanche Sunday, which partially buried one of their party members.
