Regions

Sugarbowl, Kakwa, McGregor, Pine Pass, Renshaw, Robson.

Continue to make conservative terrain choices.

Fresh wind and snow are keeping the avalanche problem alive.

Confidence

Low

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain due to a limited number of field observations.
  • We are uncertain due to how buried persistent weak layers will react with the forecast weather.

Avalanche Summary

On Sunday, a few large (up to size 3), explosive triggered wind slab avalanches were reported, along with one natural wind slab. These generally occurred in steep terrain below ridgetops.

Looking forward, with continued snowfall and strong winds, we expect that human triggered avalanches will remain likely.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

Most areas will get another dose of new snow and strong wind, forming fresh and reactive slabs. Expect to find, deeper, denser, reactive slabs on leeward slopes.

50-75 cm below the surface, a layer of weak, sugary facets buried in late February has been found in some areas. It has not produced many reported avalanches, but it is continuing to react in snowpack tests, and continuing snowfall is increasing the load on this layer.

80-120 cm below the surface is a frozen crust that was buried in earlier February.

The remainder of the snowpack is consolidated with no layers of concern.

Weather Summary

Monday Night

Mostly cloudy. 3 to 10 cm of snow. 25-60 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Tuesday

Mostly cloudy. 4 to 15 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Wednesday

Mostly cloudy. 5 to 25 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Thursday

Mostly cloudy. 3 to 10 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • In times of uncertainty, conservative terrain choices are our best defense.

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.
