Regions

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

There have been no reported avalanches in a week, but a weak layer is still reactive in tests.

Take extra care in areas with shallow snowpack.

Confidence

High

We are confident due to a stable weather pattern.
We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

January 16 to 24

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

Snowpack Summary

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

Below 1300 m and on south facing slopes a crust is present on or under the recent snow. This crust has a layer of surface hoar that is growing on it.

A weak layer of facets is buried 80 to 150 cm deep. In shallow snowpack areas, the bottom half of the snowpack is composed of weak depth hoar.

Weather Summary

Saturday Night
Clear skies. 20 km/h west ridgetop wind. Treeline temperature -7 °C.

Sunday
Sunny. 20 km/h west ridgetop wind. Treeline temperature -11 °C.

Monday
Mostly cloudy. 2 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Tuesday
Mostly cloudy. 5 to 15 cm of snow. 70 km/h ridgetop wind. Treeline temperature - 3°C.

Terrain and Travel Advice

Avoid areas with a thin or variable snowpack.
Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

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.
