Regions

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

Be cautious in thin snowpack or rocky areas where triggering a deeper layer may be possible.

Confidence

Moderate

  • Uncertainty is due to limitations in the field data.

Avalanche Summary

January 16 to 19

  • No new avalanches reported but observations are limited. Consider posting to the MIN if you are out in the mountains!

January 15

  • Large natural avalanches (size 3) where reported and may have been a day old.

  • A small (size 1) persistent slab was remotely triggered near log cabin.

January 14

  • A large (up to size 3.5) natural avalanche cycle occurred during periods of rapid loading and warming. Breaking mature timber and going through lake ice at Bryant lake.

Snowpack Summary

The upper 30 to 40 cm has been redistributed by extreme southerly wind with scoured south facing slopes and loaded, pressed and altered, north facing slopes.

Below 1200 m and on south facing slopes a crust is present on or under the recent snow.

A weak layer of facets is buried 70 to 100 cm deep. In shallow snowpack areas, the bottom half of the snowpack is composed of weak depth hoar.

Weather Summary

Monday Night
Partly cloudy. 10 km/h east ridgetop wind. Treeline temperature -7 °C with an above freezing layer between 1500 m to 2600 m.

Tuesday
Mostly cloudy. 10 km/h northwest ridgetop wind. Treeline temperature -6 °C.with an above freezing layer between 1500 m to 2600 m.


Wednesday
Mostly sunny. 20 km/h north ridgetop wind. Treeline temperature -9 °C. Freezing level 900 m.

Thursday
Mostly sunny. 20 km/h northeast ridgetop wind. Treeline temperature -12 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.

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.
