Lizard-Flathead, Flathead, Lizard.

Watch for signs of instability, like shooting cracks, as you move into steeper terrain.

Choose smaller test slopes before committing to large features.

Avalanche Summary

On Wednesday, a size 2 wind slab was skier-triggered on a SE aspect at 1950 m elevation. A large (size 2) storm slab avalanche was triggered utilizing explosives near Fernie. It was initiated on a NE aspect and ran 500 meters.

Several small (size 1-1.5) storm slab avalanches were triggered with explosives near Fernie on Tuesday.

Numerous explosive and rider-triggered large (size 2) storm slabs were reported near Fernie on Monday.

Snowpack Summary

20 to 30 cm of recent snow adds on top of the early February rain crust now buried 40 to 50 cm deep, which seems well-bonded at lower elevations but isn't bonding well at higher elevations.

There are crusts and facets in the mid and lower snowpack but have not produced any recent avalanches.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
