While wind and snow should ease through Thursday, dangerous avalanche conditions may persist. Avoid avalanche terrain during heavy snow or strong wind.

Moderate

• We are confident the likelihood of avalanches will increase with the forecast weather.
• We are uncertain about forecast snowfall amounts.

Several rider-triggered storm slab avalanches, up to size 1, were reported on Tuesday, generally failing within the top 20 cm of the snowpack.

With additional snow and wind in the forecast, these storm slabs will likely grow in size and become more reactive.

Unsettled weather continues to deliver variable snowfall across the region. Up to 50 cm of new snow may now bury a widespread crust up to 2000 m, formed during last weekend’s rain event. This crust is thin or absent at higher elevations. Strong southerly winds have redistributed the new snow in exposed terrain, while snow remains generally low-density in sheltered areas.

The mid and lower snowpack are generally well settled with no significant concerns at this time.

Wednesday Night
Cloudy. 20 to 30 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Thursday
Cloudy. 5 to 15 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Friday
Mostly cloudy. 5 to 10 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Saturday
Mostly sunny. 1 to 3 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -8 °C.

• Use increased caution at all elevations. Storm snow is forming touchy slabs.
• Avoid freshly wind-loaded terrain features.
• Keep in mind a buried crust offers an excellent bed surface for avalanches.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
