Evaluate your line for windslab - gusty winds are quickly redistributing loose snow.
Steady winds will continue to impact snow in open terrain, variable winds may reverse-load features. Investigate for wind slab around ridges or lee features.
Early reports Thursday witnessed blowing snow and winds quickly redistributing fresh flurries to lee features.
On Tuesday, explosives triggered several thin wind slabs up to size 2 in open areas above treeline. In the Nigunsaw area, a skier triggered a 35 cm thick slab on a steep roll, failing on large surface hoar on a crust. Evidence of older avalanches to size 2, 20 to 30 cm deep were also reported, failing on either surface hoar or a crust.
Up to 20 cm of fresh flurries covered 10 to 30 cm older, wind-affected snow. Steady winds are quickly impacting any loose snow.
The crust from early December is now buried 20 to 40 cm. In some areas, large surface hoar crystals are found at this interface. We are trying to track this surface hoard distribution across the region - most recently, the layer was reactive to skiers in the Ningunsaw area.
Below, the lower snowpack has no layers of concern.
