Human triggered avalanches are likely, use extra caution on lee slopes at ridgeline.
Careful snowpack evaluation, cautious route-finding, and conservative decision-making essential.
Storm slabs may continue to be reactive to human triggering. Back off if you encounter signs of instability like whumpfing, shooting cracks or recent avalanches.
No new reports by Tuesday afternoon. On Monday, observations noted a widespread natural and explosive control avalanche cycle up to size 3.
Reactive storm slabs are likely on Wednesday. Especially in areas at upper elevations that see more wind effect. Dry loose sluffing will exist in steep terrain features.
Up to 120 cm of settling storm snow sits above a crust on all aspects except high north facing slopes, where it sits on faceted snow that formed early March. Strong southwest winds have redistributed storm snow into toucy slabs on leeward slopes at the ridgeline. Below treeline the storm snow is settling out rapidly.
A layer of facets and surface hoar from mid February can be found down 100 to 140 cm.
Another layer of facets and surface hoar from late January can be found down 140 to 200 cm.
