Avalanche Forecast

Many large (size 2 to 3) wind slabs were observed on southerly slopes on Tuesday. Most of the avalanches were naturally triggered from the rapid loading caused by strong northeast wind. Riders were also able to trigger a few storm slab avalanches within the recent storm snow.

Looking forward, we anticipate that wind slabs will be triggerable on south to west aspects. These slopes are atypical for a wind slab problem so use caution when in wind exposed terrain.

Strong northeast wind formed touchy wind slabs in lee terrain features in wind-exposed terrain. The slabs are on atypical south to west aspects. The frigid weather will slow the healing process, meaning these slabs could remain touchy for longer than is typical.

The middle of the snowpack is generally strong.

A weak layer of large and weak facets is found near the base of the snowpack. The layer is currently dormant. However, riders should continue to avoid thin, rocky terrain where the likelihood of triggering this layer is increased.

Wednesday Night

Mostly clear skies with no precipitation, 40 to 60 km/h northeast wind, treeline temperature -31 °C.

Thursday

Clear skies with no precipitation, 40 to 50 km/h northeast wind, treeline temperature -29 °C.

Increasing clouds with afternoon snowfall, trace accumulation, 40 km/h west wind, treeline temperature - 21 °C.

Cloudy with snowfall, accumulation 5 cm, 40 to 50 km/h southwest wind, treeline temperature -14 °C.

• Expect slab conditions to change drastically as you move into wind exposed terrain.
• Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
