Avalanche Forecast

Moderate

There was further evidence of deep persistent slab activity from the past week. Riders should continue to avoid steep, thin, rocky slopes, particularly near alpine ridgelines.

Looking forward, we anticipate that wind slabs will remain possible to be human triggered.

Strong northeast wind formed touchy wind slabs in lee terrain features in wind-exposed terrain. The wind will switch to southwest on Friday, possible forming new slabs. This means wind slabs may be found on all aspects. The frigid weather will slow the healing process, meaning these slabs could remain touchy for the coming days.

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, except in very steep alpine terrain that is inherently shallow. Riders should continue to avoid thin, rocky terrain where the likelihood of triggering this layer is increased.

Thursday Night

Clear skies with no precipitation, 20 km/h east wind, treeline temperature -26 °C.

Friday

Increasing clouds with afternoon snowfall, accumulation 1 to 3 cm, 40 km/h west wind, treeline temperature - 21 °C.

Cloudy with snowfall, accumulation 5 to 10 cm, 40 to 50 km/h southwest wind, treeline temperature -14 °C.

Cloudy with snowfall, accumulation 5 to 15 cm, 20 to 30 km/h southwest wind, treeline temperature -14 °C.

• Expect slab conditions to change drastically as you move into wind exposed terrain.
• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
