Avalanche Forecast

Moderate - Uncertainty is due to the limited number of field observations.

THURSDAY NIGHT: Partly cloudy with no precipitation, 10 to 20 km/h north wind, alpine temperature -22 C.

FRIDAY: Clear skies with no precipitation, 10 to 20 km/h north wind, alpine temperature -22 C.

SATURDAY: Cloudy with snowfall, accumulation 2 to 5 cm, 30 to 60 km/h southwest wind, alpine temperature -17 C.

SUNDAY: Cloudy with snowfall, accumulation 5 to 15 cm, 20 to 40 km/h southwest wind, alpine temperature -14 C.

A suspected persistent slab avalanche was observed in the region on Wednesday, that released naturally within the past couple of days. It likely started around 2200 m on a steep northwest aspect. Information on its release was not available due to poor visibility.

We'd appreciate if you submit your observations to the Mountain Information Network, even just a photo.

Thin wind slabs may have formed from Wednesday night's 5 cm of snow and wind from variable directions. These slabs could remain touchy to riders, as they sit on previously wind-affected snow, sugary faceted grains, and/or surface hoar in areas sheltered from the wind.

A weak layer of feathery surface hoar may be found around 20 to 50 cm deep. It is most likely found in sheltered terrain features in the lower alpine and treeline, or open features below treeline (e.g., cut blocks). Although we haven't received reports of this layer being a concern, it has been noted in neighbouring regions.

Sugary faceted grains may be found around the early-December melt-freeze crust 60 to 100 cm deep. The layer exists up to around 2000 m. This layer is spatially variable and may only be a problem in select parts of the region. Read more about it here. We haven't received reports of recent avalanche activity on this layer. 

• Carefully evaluate steep lines for wind slabs.
• Make observations and assess conditions continually as you travel.
