Thin wind slab avalanches may remain possible to trigger on leeward terrain features such as ridgecrests and roll-overs.
Be cautious of wind slabs in steep alpine terrain.
Thin wind slab avalanches may remain possible to trigger on leeward terrain features such as ridgecrests and roll-overs.
There were a few size 1-1.5 explosives triggered avalanches on east and southeast aspects in the alpine on Saturday.
30 to 60 cm of dry snow sits above a rain crust. The greatest amounts are likely around Fernie, but any leeward terrain could have deeper deposits due to the recent southwest wind. Reports suggest the snow is bonding well to the crust. You may also find a thin crust near the surface in some areas. The lower snowpack was rain-soaked and has slowly refrozen. Typical snowpack depths at treeline are 75 to 130 cm, and taper rapidly below treeline.
