Avalanche Summary

Large explosives created avalanches to size 1.0 in the North of the region. Loose snow avalanches up to size 1.0 were reported across the region.

Snowpack Summary

Thin wind slabs continue to develop with each pulse of snow and wind. Most of the precipitation has been tracking along the U.S. border, so the southern parts of this region may have quite a bit more new snow than the North. Areas with sheltered terrain have been reporting no new shears in the recent storm snow. Unconsolidated snow with thin wind slabs in exposed terrain in the alpine and at treeline has been reported from most areas.
