Regions

Haines Pass, Chilkat Pass.

Stable, cool weather is reducing the likelihood of triggering deep weak layers. Continue to travel cautiously in shallow snowpack areas, rocky slopes and near cornices.

Confidence

Low

  • We are uncertain about how quickly persistent slabs are gaining strength.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanche activity has been reported.

We suspect small wind slab avalanches are possible to human trigger, especially at upper elevations in steep terrain features.

Snowpack Summary

Recent incremental accumulation of light snow is being redistributed by moderate west wind developing isolated wind slabs.

Below this most recent snow there are various old surfaces. Wind-pressed in exposed terrain. Settled soft snow and/or faceted in sheltered north aspect and sun crust on solar-facing slopes.

A persistent weak layer of facets and crust is buried 80 to 150 cm deep, extending up to about 1400 m. The greatest concern for triggering comes from large loads, such as cornice falls, or from human triggering in areas where the snowpack transitions from thin to thick.

Weather Summary

Wednesday Night
Cloudy. 20 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Thursday
Cloudy. 2 to 4 cm of snow. 10 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Friday
Mix of sun and clouds. 3 cm of snow. 30 km/h northeast ridgetop wind. Treeline temperature -3 °C.

Saturday
Sunny. 30 km/h north ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Be aware of the potential for large, destructive avalanches due to deeply 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.

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.

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.
