Regions

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

The season is off to a great start in White Pass

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

Avalanche Summary

We have received a report of wind slab avalanches in steep terrain, but details are limited.

In general, observations are limited this time of year.

Snowpack Summary

The winter is off to a great start in the White Pass!

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

Wednesday Night

Mix of cloud and clear skies. 5 to 20 km/h east alpine wind. Treeline temperature -12°C, potential for temperature inversion with colder temps at highway elevation.

Thursday

Mix of sun and cloud with trace amounts of snow possible. 10 to 25 km/h east alpine wind. Treeline temperature -12°C, potential for temperature inversion with colder temps at highway elevation.

Friday

Mostly cloudy. 10 to 25 km/h east alpine wind in the morning and 15 to 30 km/h southwest alpine wind in the afternoon. Treeline temperature -8°C, potential for temperature inversion with colder temps at highway elevation.

Saturday

Mostly cloudy with trace amounts of snow. 15 to 30 km/h southwest alpine wind . Treeline temperature -6°C, potential for temperature inversion with colder temps at highway elevation.

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.
