Regions: North Columbia.

Dry snow can be found on north-facing alpine slopes, but this is where triggering slab avalanches may still be possible.

Avalanche Summary

On Friday, a few large (size 2-3) skier triggered slab avalanches were reported on north-facing slopes above 2300 m. Some other smaller slabs have been reported in the same type of terrain over the past few days, highlighting the fact winter-like conditions can still be found in shaded alpine terrain. Small loose wet avalanches remain possible on sun-exposed slopes.

Snowpack Summary

Most slopes have entered a daily melt-freeze cycle, with the exception of north-facing terrain above roughly 2000 m. On these colder slopes, you may find 10-30 cm of dry powder or isolated wind slabs. These same slopes may also have a layer of faceted grains buried 50 to 70 cm below the surface. This layer has been responsible for a few large isolated avalanches over the past few days. Elsewhere, the surface has been melting each day and then freezing into a hard crust overnight. Snow is disappearing rapidly at lower elevations.

Avalanche Problems

Wind Slabs

Slab avalanches remain possible to trigger in shaded alpine terrain, particularly on large steep convex rolls.
Watch for signs of instability such as whumpfing, or cracking. Be careful around wind loaded pockets near ridge crests and roll-overs.Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

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