15 to 30 cm of new snow and strong southwest wind will build touchy storm slabs. Avoid lee slopes at ridgeline.
Stick with a conservative trip plan and watch for signs of instability.
Touchy storm slabs are likely on Wednesday. Back off if you encounter signs of instability like whumpfing, shooting cracks or recent avalanches.
Dry loose sluffing is likely in steep terrain features.
No recent reports by Tuesday afternoon.
On Monday, explosive control produced one storm slab (size 1.5), and the AvCan field team observed one size 2 storm slab that they suspect was remotely triggered by a snowmobile.
New snow and strong to extreme southwest wind may form touchy storm and wind slabs on Wednesday.
New snow accompanied by strong to extreme southwest wind will likely form fresh wind slabs at upper elevations on Wednesday.
This brings 80 to 120 cm (deeper totals in leeward terrain) of recent storm snow, which sits above a crust and a mix of facets and surface hoar that formed earlier this month. The mid and lower snowpack is strong and dense with depths of near 400 cm at treeline elevations.
