Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

Terrain sheltered from the wind will have the best and safest riding.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

On Friday, explosives control targeting buried weak layers with large explosives triggered one large (size 2.5) persistent slab near Pine Pass. This occurred on a south aspect at treeline.

On Thursday, there were several dry loose avalanches.

Snowpack Summary

Up to about 40 cm of snow since March 7 overlies wind-affected old surfaces in the alpine and a crust that extends to ridgetop. Wind slab formation from easterly winds occurred with the earlier storm, now buried by either low density snow or more westerly wind transport. The crust becomes supportive at lower elevations and is 5 cm thick below 1400 m.

Another crust with faceted snow above, buried at treeline and below in February, is found around 100 to 160 cm deep. It's becoming well bonded to the surrounding snow and at lower elevations will be capped by more recent crust.

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

Weather Summary

Saturday Night
Partly cloudy. 2 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -12 °C.

Sunday
Mostly cloudy. 2 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Monday
Mostly cloudy. 20 to 30 cm of snow above 1800 m, rain below. 70 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Tuesday
Mostly cloudy. 10 to 55 mm of rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature 2 °C.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
