Regions

Sugarbowl, Kakwa, McGregor, Pine Pass.

Wind slabs are the primary concern. Watch for soft pockets of fresh wind slab as well as old, stiff wind slabs in leeward terrain features at upper elevations.

Confidence

No Rating

  • We are uncertain whether the wind will be enough to form new wind slabs.

Avalanche Summary

During the storm on the weekend, a widespread natural avalanche cycle occurred, with wind slabs to size 3.5 on north to east aspects at upper elevations and loose wet up to size 2 below treeline.

Since then, the only report of avalanche activity was a size 1 loose dry ski cut running on the recent crust in steep terrain at treeline.

Snowpack Summary

10-20 cm of dry snow may form fresh pockets of wind slab over a firm wind-sculpted upper snowpack and crust below 1600m.

A crust buried in February exists at variable depths, generally 100 to 160 cm deep. 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

Tuesday Night
Mostly cloudy. 2 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Wednesday
Mostly cloudy. 2 to 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Thursday
Mostly cloudy. 2 to 3 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -12 °C.

Friday
Mostly sunny. 1 to 3 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • 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.
