Avalanche Summary

No new avalanches were observed in the region on Monday.

Snowpack Summary

Tuesday's storm brought around 5 to 10 cm of snow to the region, with associated strong west wind. This snow accumulated onto a variety of hard slabs, wind-pressed snow, sastrugi, sugary faceted snow, and melt-freeze crust. In sheltered areas at and below treeline, the new snow may have fallen onto pockets of feathery surface hoar crystals and soft, faceted snow.In the south of the region, the remainder of the snowpack is well-settled. In the north of the region, around 50 cm of snow may overly a weak layer of surface hoar or faceted grains.

Avalanche Problems

Wind Slabs

New wind slab avalanches may have formed in exposed terrain from recent snow and strong wind. Use caution in lee features near ridges.
Be careful around wind loaded pockets near ridge crests and roll-overs.Watch for patterns of wind loading if you venture into wind affected terrain.

Aspects: North, North East, East, South East, South, North West.
