Regions

North Rockies, McBride, Sugarbowl, Kakwa, McGregor, Renshaw, Robson.

Expect dangerous avalanche conditions. Avoid avalanche terrain during and after the storm.

Check out the Forecaster Blog on how to manage the changing conditions.

Confidence

Moderate

Avalanche Summary

A few small wind slabs were reported yesterday.

We expect avalanche activity to increase in frequency and size through the weekend.

Snowpack Summary

Up to 50 cm of new snow overlies a surface hoar layer, particularly around treeline elevations and below. In sun-exposed terrain, surface hoar may rest atop a thin crust, while elsewhere it sits atop a mix of old wind-affected surfaces and weak, faceted snow.

A widespread crust with facets and/or surface hoar, buried in mid-January, is approximately 30 to 70 cm below the surface.

The mid and lower snowpack is well-settled.

Weather Summary

Friday night

Cloudy with 10 to 15 cm of snow. 20 to 40 km/h south ridgetop wind. Treeline temperature - 15 °C.

Saturday

Mostly cloudy. 10 to 20 km/h south ridgetop wind. Treeline temperature -20 °C.

Sunday

Mostly cloudy with 0 to 5 cm of snow. 10 to 30 km/h south ridgetop wind. Treeline temperature -25 °C.

Monday

Mostly cloudy. 10 to 30 km/h east ridgetop wind. Treeline temperature -25 °C.

Terrain and Travel Advice

  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
  • Avoid avalanche terrain during periods of heavy snowfall.

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.
