Regions

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

We have uncertainty in this region, make assessments as you move through terrain

Up high small wind slabs may exist, lower down early season hazards could be just below the surface

Confidence

Low

Avalanche Summary

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

In general, observations are limited this time of year.

Snowpack Summary

Wind has varied in direction over the past couple 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

Thursday Night

Mix of clear sky and cloud. 10 to 25 km/h south alpine wind. Treeline temperature -5°C, potential for temperature inversion with colder temps at highway elevation.

Friday

Mostly cloudy with trace amounts of snow possible. 10 to 30 km/h southwest alpine wind. Treeline temperature -5°C, potential for temperature inversion with colder temps at highway elevation.

Saturday

Mostly sunny. 15 to 25 km/h southwest alpine wind . Treeline temperature -5°C, potential for temperature inversion with colder temps at highway elevation.

Sunday

Cloudy with 5 to 10 cm of snow. 10 to 30 km/h south alpine wind. Treeline temperature -7°C.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
  • Be careful as you transition into wind-affected terrain.

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.
