Consider the consequences of any fall in steep terrain, and continue to use safe travel habits.
Rider triggered avalanches are still possible.
Moderate southwest through northwest winds have likely formed deeper, more reactive pockets of snow in leeward terrain near ridgetops. These slabs may not be bonding well to the hard surfaces or weak snow crystals that they cover.
On Tuesday a loose wet avalanche cycle was reported on all aspects, but confined to terrain below 1800m and on terrain steeper than 35 degrees.
On Monday, there were several small to large (up to size 2) rider triggered and natural avalanches reported, generally wind slabs in north or northeast facing high alpine terrain.
On Saturday, north of Revelstoke there was a large (size 3) persistent slab avalanche triggered by a helicopter landing at 2300 m on a northeast aspect.
A frozen crust has form on the surface, possibly as high as 2500 m. 5-15 cm of new snow may be on the surface at high elevations in the north end of the forecast area.
In general, 20 to 40 cm of settling snow snow sits on surface hoar crystals that were buried in late March. Under that is a hard melt freeze crust on all aspects and elevations other than north facing alpine.
Weak faceted grains above a hard crust that formed in early February are buried around 100 to 150 cm deep. This layer is generally getting stronger, and in most places it is shielded by crusts above, but it is still occasionally producing large avalanches.
