Regions

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

Conditions vary across the region, but a persistent weak layer remains the common thread.

Be patient, assess continuously, and choose conservative terrain

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

No new avalanches have been reported.

Aerial observations in White Pass on Thursday included several recent natural persistent slabs to size 2.5, mainly on southeast to southwest aspects.

Snowpack Summary

Roughly 10 to 15 cm of snow has incrementally accumulated and redistributed by moderate wind building small wind slabs over various old surfaces:

  • In the high alpine a surface hoar layer may remain intact on sheltered northerly terrain.

  • Hard, pressed surfaces, wind slab, and sastrugi in exposed terrain.

  • A crust should be found on or near the surface of sun-exposed slopes and lower elevations.

The lower snowpack is faceted and generally weak, particularly in shallow areas.

Weather Summary

Monday Night
Cloudy. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -3 °C.

Tuesday
Mostly cloudy. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -5 °C.

Wednesday
Mostly cloudy. 1 to 4 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -6 °C.

Thursday
Mostly cloudy. 2 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Wind slabs are isolated, but may remain reactive.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
