Regions

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

New snow, strong winds and warm temperatures are keeping storm slabs reactive.

Stick to conservative terrain during this period of active weather.


Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

No new avalanches have been reported.

With up to 40 cm of new snow and strong winds in the forecast, the avalanche danger is elevated. This means large natural avalanches are possible and human-triggering is likely.

Observations are still limited, so be sure to post yours to the MIN if you get out!

Snowpack Summary

Up to 40 cm of new snow has accumulated since Monday, accompanied by strong southerly winds. Freezing levels have hovered around 1200 m. The snow surface will be moist and rain-saturated below this elevation. The highest snowfall amounts are in the White Pass area, with lesser amounts inland.

A crust buried on Jan 26th is being reported down 40 to 60 cm. On northern and eastern aspects, a layer of surface hoar exists over the crust in some places.

A layer of facets from December is buried down 90–280 cm. It remains a concern where the snowpack transitions from thin to thick in White Pass and is the layer of concern in inland areas with a lower snowpack.

Weather Summary

Wednesday Night
Mostly cloudy. 4 to 10 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1300 m.

Thursday
Cloudy. 1 to 4 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1200 m.

Friday
Mostly cloudy. 2 to 3 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 800 m.

Saturday
Mostly cloudy. 4 to 5 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.

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.
