Regions

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

Seek out areas where the surface snow is soft and avoid areas where the surface snow is heavy and has been wind affected.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

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

Expect to find soft snow in sheltered areas, and wind slab on leeward slopes.

Wind has varied in direction over the past few days, expect exposed areas to be generally wind-affected.

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

Friday Night
Cloudy. 10 cm of snow. 20 km/h east ridgetop wind. Treeline temperature -15 °C.

Saturday
Cloudy. 10 to 15 cm of snow. 30 km/h northeast ridgetop wind. Treeline temperature -18 °C.

Sunday
Mostly cloudy. 5 to 8 cm of snow. 25 km/h northeast ridgetop wind. Treeline temperature -15 °C.

Monday

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Make observations and continually assess conditions as you travel.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.

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.
