Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

A widespread surface crust is creating stable avalanche conditions, but is making travel challenging.

Confidence

High

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Trace amounts of dry snow have begun to accumulate atop a widespread hard crust. In general, the crust is strong and supportive to travel on.

In the midpack, a weak facet layer persists, but has become unlikely to trigger with a supportive crust above.

Areas in the east of the region are largely characterized by a shallow and faceted snowpack.

Weather Summary

Monday Night

Mostly clear with no precipitation, southeast alpine winds 20 to 30 km/h, treeline temperature -8 °C.

Tuesday

Mix of sun and cloud with no precipitation, southwest alpine winds 20 to 30 km/h, treeline temperature -8 °C.

Wednesday

Mostly cloudy with no precipitation, southeast alpine winds 20 to 30 km/h, treeline temperature -8 °C.

Thursday

Mostly cloudy with no precipitation, southwest alpine winds 20 to 30 km/h, treeline temperature - 10 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Carefully evaluate big/extreme terrain features before committing to them, it's not full "go" time yet.
  • Expect shallow snow cover that barely covers ground roughness.

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.
