Regions

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

We have uncertainty due to limited observations, make assessments as you move through terrain.

Up high wind slabs may exist, low down early season hazards are just below the surface.

Confidence

Low

Avalanche Summary

We haven't received any reports of avalanche activity since last weekend.

In general, observations are limited this time of year.

Snowpack Summary

Wind has varied in direction over the past few days, wind slabs could be found on all aspects.

Below ridgetops there is an above average snowpack depth of 100 cm. Snowpack depth tapers with elevation to around 60 cm at the highway. Many early season hazards are just below the surface at this elevation.

Currently there are no layers of concern but data is limited. Thanks to everyone who has already submitted Mountain Information Network reports.

Weather Summary

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be careful as you transition into wind-affected 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.
