Regions

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

Be cautious in steep, wind-affected terrain where triggering slabs is most likely.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanches have been reported in the past few days.

If you head out in the backcountry, let us know what you're seeing by submitting a MIN report.

Snowpack Summary

Up to 10 cm of new snow overlies heavily wind-affected surfaces in open areas at all elevations. Up to 50 cm of soft snow can be found in sheltered areas.

A mid-February crust or facet layer sits 50 to 70 cm deep, and the late January crust/surface hoar layer is buried 50 to 100 cm deep. These layers have shown no recent reactivity.

Facets or depth hoar exist at the base of the snowpack and may be a concern in inland areas, where the snowpack is generally shallower.

Weather Summary

Monday Night
Mostly cloudy. 3 cm of snow. 10 km/h southeast ridgetop wind. Treeline temperature -15 °C.

Tuesday
Mostly cloudy. 3 to 5 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -16 °C.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -14 °C.

Thursday
Mix of sun and clouds. 3 to 5 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -11 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Wind slabs are isolated, but may remain reactive.

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.
