Regions

Yukon, Tutshi, Wheaton, White Pass East, White Pass West.

Human triggered wind slabs are still possible.

Take into account the cold temperatures, add extra buffer time and maintain a larger safety margin throughout the day.

Low

Avalanche Summary

No recent reports this week. Over the weekend, remotely triggered storm and wind slabs (up to size 2) were reported in the Fraser Chute East area and at Log Cabin.

In general, observations are limited this time of year. Be sure to verify conditions as you go.

If you are getting out in the backcountry, consider making a post on the MIN.

Snowpack Summary

Wind has varied in direction over the past few days, expect exposed areas to stiff wind-affected snow wind slab. The cold temperatures will likely promote faceting in the upper snowpack.

A crust is buried from 15 to 20 cm under the new snow.

Below ridgetops, there is an average snowpack depth of 110 cm. Snowpack depth gradually thins as elevation decreases to around 60 cm at the highway.

Many early-season hazards are just below the surface at this elevation.

Weather Summary

Tuesday Night
Clear skies. 30 km/h northeast ridgetop wind. Treeline temperature -30 °C.

Wednesday
Sunny. 30 km/h northeast ridgetop wind. Treeline temperature -30 °C.

Thursday
Sunny. 20 km/h northeast ridgetop wind. Treeline temperature -32 °C.

Friday
Sunny. 20 km/h west ridgetop wind. Treeline temperature -28 °C.

Terrain and Travel Advice

  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
  • Make observations and continually assess conditions as you travel.

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.
