Regions

Sugarbowl, Kakwa, McGregor, Pine Pass.

Recent snow will likely remain reactive to human triggers, especially in wind-loaded terrain at upper elevations.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Storm slabs have been reactive in recent days. There have been numerous reports of natural and skier-triggered size 1-2 storm slab avalanches on a variety of aspects, at all elevations, 20-40 cm deep.

Snowpack Summary

20 to 50 cm of recent snow has been redistributed by wind at upper elevations. Below 1500 m, expect moist or crusty surfaces.

A crust buried in February exists at variable depths, generally 50 to 120 cm below the surface. For the most part, it is well bonded to the surrounding snow but in isolated, wind-sheltered areas, weak surface hoar crystals may sit atop this crust.

The remainder of the snowpack is consolidated with no other significant layers of concern.

Weather Summary

Saturday Night
Mostly cloudy. 2 to 5 cm of snow. 80 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level dropping 1500 m to valley bottom.

Sunday
Mostly cloudy. 1 to 2 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -8 °C.

Monday
Mix of sun and clouds. 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -9 °C.

Tuesday
Mix of sun and clouds. 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Use careful route-finding and stick to moderate angled slopes with low consequences.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Be especially cautious as you transition into wind-affected terrain.

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.
